The synthesized adsorbent was characterized and identified using techniques like Transmission electron microscopy (TEM) and Brunauer–Emmett–Teller (BET). The effective parameters of the removal process were investigated and optimized by experimental design methodology (EDM) based on response surface methodology (RSM) as a powerful optimization method. EDM is a unique method for following the effects of different factors on the removal process simultaneously. Analysis of variance (ANOVA) was used based on p-values and F-tests to investigate the accuracy and reliability of the used method. The optimized parameters were obtained as BPB concentration of 15 mg L<sup>-1</sup>, ultrasonic irradiation time of 14 min, adsorbent dosage of 0.018 g and pH= 5.5 under the desirability function. To evaluate the adsorption mechanism and calculation of maximum adsorption capacity, different adsorption isotherms were studied and according to the results, the Langmuir isotherm model showed the highest compatibility due to its higher R<sup>2</sup> (0.9905). Also, the proposed adsorbent represented good adsorption capacity (123.45 mg g<sup>-1</sup>).&nbsp;</p> saeid Khodadoust, Corresponding Author,, Raana Ghadri, Fatemeh Zeraatpisheh (Author) ##submission.copyrightStatement## Thu, 28 Mar 2024 00:00:00 +0000 Determine methylene blue based on carbon paste electrode modified with nanoparticles of nickel oxide-nitrogen carbon quantum dots and carbon structures by cyclic voltammetry <p>This paper deals with an electrochemical method for the determination of methylene blue (MB) by fabrication of an electrode based on a carbon paste modified with nano-nickel oxide and nitrogen carbon quantum dots (NiO-NCQD), graphene-carbon nitride (g-C<sub>3</sub>N<sub>4</sub>), reduced graphene oxide (rGO), and graphite powder and paraffin oil are as a plasticizer. This electrode is used as a working electrode. &nbsp;The analytical method used is cyclic voltammetry (CV), The oxidation-reduction curve of methylene blue was shown using this electrode. It is a quasi-reversible curve, and it works at (pH =1) and the best acid used is HCl a concentration of (0.1M). It was also found that the linear range is within the range of (7.99-31.98 mg L<sup>-1</sup>). The standard deviation (SD) and relative standard deviation (RSD%) were obtained at (0.361 mg L<sup>-1</sup> and 0.294 mg L<sup>-1</sup>) and (4.52% and 3.68%) for both oxidation and reduction respectively. Retrospective, the limit of quantitative (LOQ) and limit of detection (LOD) were achieved at (99.65%; 99.70%), (0.24 mg L<sup>-1</sup>; 0.13 mg L<sup>-1</sup>), and (0.071 mg L<sup>-1</sup>; 0.039 mg L<sup>-1</sup>) for both oxidation and reduction respectively.

The prepared material was characterized by modern spectroscopic methods for confirming the successful embedding. The adsorption experiments were conducted in batch systems. The experimental data showed robust removal of chromium supported by kinetic and equilibrium studies. The sorption data exhibited a strong agreement with the pseudo-second-order kinetics model, further confirming conformity with the Langmuir isotherm model. Adsorption studies were taken to find the effects of pH and time, reusability, ionic strength and presence of coexisting ions. The maximum sorption capacity was achieved as 14.28 mg g<sup>-1</sup> at pH 4 and the optimum contact time was 40 minutes. The background electrolytes have much less effect on uptake efficiency and this green adsorbent can be utilized for up to four cycles. &nbsp;Additionally, a systematic approach was employed to ensure the precision and accuracy of the spectroscopic method. Calibration was linear in the range from 0.5 to 6.0 μg L<sup>-1 </sup>&nbsp;(R<sup>2</sup> &gt; 0.99). The limits of detection (LOD) and quantification (LOQ) were 0.65 μg L<sup>-1&nbsp; </sup>and 2.16 μg L<sup>-1</sup>, respectively. The relative standard deviation (RSD) was 7.62 % (n=7).</p> Anurag Choudhary, Corresponding Author,, Sardar Singh Poonia (Author) ##submission.copyrightStatement## Fri, 29 Mar 2024 00:00:00 +0000 Solid phase-fabrication of multi-walled carbon nanotubes and their derivatives for efficient extraction and analysis of Bismarck Brown-Y Dye from aqueous solution <p>This investigation used efficientMWCNTs and their derivatives; MWCNT-Tris, MWCNT-H, MWCNT-Tetra and MWCNT-G, for extraction and removing the Bismarck Brown-Y (BB-Y) by solid phase extraction (SPE). The concentration of BB-Y was measured by UV-Vis spectrophotometer after the SPE technique. The solid phases were analyzed and characterized by utilizing several techniques, including Fourier Transform Infrared Spectroscopy (FTIR), FE-SEM, zeta potential measurement, and X-ray Diffraction (XRD). At&nbsp;optimization conditions, the optimum concentration of the BB-y&nbsp;was obtained at 200 mgL<sup>-1</sup> and 300 mg L<sup>-1</sup> for MWCNT and MWCNT-Tris, whereas 400 mg L<sup>-1</sup> for MWCNT-H, MWCNT-Tetra, and MWCNT-G. Additionally, the optimal pH value was 6.0 for MWCNT-Tris, and it was 10 for MWCNT, MWCNT-H, MWCNT-Tetra, and MWCNT-G. However, the volume of samples was achieved at 25 mL. Furthermore, it was found that the most effective flow rate for the eluting solvent was 0.5 ml min<sup>-1</sup>. Besides the type and volume of eluents were examined and evaluated. Finally, the present work involved the determination of adsorption capacity using Langmuir and Freundlich isotherm models under ideal conditions. The Langmuir model revealed that the <em>q<sub>max</sub></em> for the MWCNT, MWCNT-tris, MWCNT-H, MWCNT-Tetra, and MWCNT-G was obtained 862.07, 1075.27, 1282.05, 1298.70, and 1333.33 mg g<sup>-1</sup>, respectively.</p> Salah Mahdi Saleh, Ali Abdulrazzaq Abdulwahid, Corresponding Author,, Zaki Nassir Kadhim (Author) ##submission.copyrightStatement## Fri, 29 Mar 2024 00:00:00 +0000 Analytical Method: Determination of famotidine drug using chemiluminescence method <p>This study involved the development of a novel, cost-effective, fast, and highly sensitive analytical technique for quantifying minimal amounts of the drug famotidine through chemiluminescence. The method is centred around the measurement of energy emitted as a result of the interaction between the drug and Luminol in an alkaline solution; this interaction generates an electronically excited intermediate state, releasing a portion of the system’s energy as photons. The method was sensitive for the analysis of famotidine. The linear calibration curve (LR) is obtained in the range 2-12 mg mL<sup>-1</sup>, with a high correlation coefficient (R<sup>2</sup>) of 0.9929. The molecular absorption coefficient &nbsp;(ε) was calculated at 2621×10<sup>4</sup> L mol<sup>-1</sup> cm<sup>-1</sup>. The method displayed excellent sensitivity with a Sandell’s sensitivity of 1.287×10<sup>-5</sup> mg cm<sup>-2</sup>, the detection limit (LOD) was found to be 0.0314 mg mL<sup>-1</sup><sup>, </sup>and the limit of quantification (LOQ) was 0.0952 mg mL<sup>-1.</sup> This study found that recovery was obtained at 104 - 96.5 %, and the relative standard deviation (RSD%) was below 1.981%.

The study involved 50 male blood radiography workers from the medical imaging field at Al-Shatrah General Hospital in Thi-Qar City, Iraq. All workers were aged between 35-50 years and had worked for less than 10 years. The study compared these workers with 50 healthy men. The study found a significant increase in the levels of Cu, Pb, Cd, and Ca among radiography workers compared to the healthy control group, while Zn and Se levels decreased significantly. Moreover, Specificity and confidence interval (95%) were estimated via the receiver operating characteristic curve (ROC). The study provided conclusive evidence of disturbances in the levels of trace elements in the blood of radiographer workers, which makes them more susceptible to many diseases because of their radiation exposure. which portends the more preventive measures of radiation. The linear range of Cd, Cu, Zn, Se and Pb in human serum were obtained 0.2-6.0 µg dL<sup>-1</sup>, 6.0-200 µg dL<sup>-1</sup>, 8.0-200 µg dL<sup>-1</sup>, 10-250 µg dL<sup>-1</sup>, 4-120 µg dL<sup>-1 </sup>by GF-AAS after dilution samples with DW up to 20 (n=10, RSD&lt; 5%)<sup>.</sup></p> ahmed jaber ibrahim, Corresponding Author, (Author) ##submission.copyrightStatement## Sat, 30 Mar 2024 00:00:00 +0000 A review: Exploratory analysis of recent advancement in green analytical chemistry application <p>It is always a concern to ensure personnel and environment safety in the field of chemistry which has caused to development of green analytical chemistry methods.
