A customized design based on response surface methodology (RSM) was used to build predictive models and optimize heavy metal reduction. Twenty experiments were conducted to evaluate the impact of variables on the adsorption removal process of both heavy metals, including the initial concentration (IC) (A), adsorbent dose (B), and pH (C), as well as their interactions. The results indicate that increasing the pH and adsorbent dose leads to a higher removal rate for both metals, whereas increasing the initial concentration of the metals results in a lower removal rate. The interaction between variables was found to be insignificant. The statistical analysis demonstrates that both heavy metal models are highly significant with very low probability values (<i>p</i> &lt; 0.0001) and excellent predictability, with R² values exceeding 0.91 for the two metals. The optimal values for initial concentration, adsorbent dose, and pH for cadmium and lead were determined to be 10.29-10 ppm, 0.063 –0.026 g, and 4.49-5, respectively. Under these optimal conditions, the removal efficiency for cadmium and lead was found to be between 99% and 99.33%, respectively. The Langmuir model described best the equilibrium adsorption behavior, indicating a monolayer adsorption with maximum adsorption capacities of 418.04 mg/g for Pb²⁺ and 236.48 mg/g for Cd²⁺, while the pseudo-second-order model provided the best fit for analyzing the kinetics of adsorption. These findings highlight APAM as a highly effective and promising adsorbent for heavy metals remediation, which offer a viable solution for water treatment.</p></div>","PeriodicalId":676,"journal":{"name":"Journal of the Iranian Chemical Society","volume":"23 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147342052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive assessment of the serum ion profile can provide valuable insights into pathophysiological processes. Capillary zone electrophoresis (CZE) offers a promising alternative to traditional methods like ion chromatography, owing to its high speed, separation efficiency, small sample volume, and simplified sample preparation. The aim of the study is to evaluate the content of major inorganic cations (K⁺, Na⁺, Mg²⁺, Ca²⁺), anions (Cl⁻, SO₄²⁻, HPO₄²⁻, citrate, lactate), and their ratios in the blood serum of patients with lymphoproliferative diseases (LPDs) compared to healthy donors using CZE. The study involved 85 participants: 31 patients diagnosed with Hodgkin lymphoma (HL) and non-Hodgkin lymphomas (NHL), and 54 healthy donors. Analyte concentrations in serum samples were determined by CZE. Statistical analysis was performed to identify significant differences between groups. Patients with LPDs exhibited statistically significant alterations in their ion profile compared to healthy donors. Elevated concentrations of potassium (p &lt; 0.0001), sulphates(p = 0.0167), and lactate (p &lt; 0.00001) were observed, alongside a decrease in ionized calcium levels (p = 0.0253). Consequently, a significant reduction in the Na/K (p = 0.0013) and Ca/Mg (p = 0.0315) ratios was noted in the patient group. Comparison of patient subgroups showed that there were no statistically significant differences in the content of the studied analytes in patients with NHL and HL. The findings indicate a profound and complex dysregulation of electrolyte and metabolic homeostasis in patients with lymphoproliferative diseases. The identified changes, particularly elevated lactate and potassium levels, and altered ion ratios, can serve as additional biochemical markers for assessing disease severity and monitoring patient status. The CZE method demonstrated its effectiveness for rapid and accurate multicomponent analysis of blood serum.</p>\u0000 </div>","PeriodicalId":676,"journal":{"name":"Journal of the Iranian Chemical Society","volume":"23 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147341336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organophosphorus pesticides are one of the most commonly used classes of pesticides. The constant use of these pesticides has contaminated the environment, and possibly put human health at risk. However, pesticide levels in different matrices are generally below the limits of detection for many analytical instruments and have high matrix interference, making them impossible to analyze directly from samples. In order to maximize the analytical performance of highly sensitive and sophisticated instruments and to obtain trustworthy analytical results, sample preparation is a critical step in the development of pesticide residue analysis. This review describes the sample preparation techniques of two broad category namely solvent extraction techniques and sorbent extraction techniques that have been proposed since 2016 for the extraction of globally used organophosphorus pesticides. The key features of various sample preparation techniques are discussed with an emphasis on optimal parameters and notable advantages-disadvantages. Based on the present review, QuEChERS and LPME emerge as the most widely employed sample preparation techniques for the analysis of organophosphorus pesticides. QuEChERS is predominantly preferred for food matrices due to its high throughput, simplicity and efficiency. SBSE is the choice of approach for environmental samples while LLE and its miniaturization techniques have been successfully utilized for the extraction of OPPs from lipid-rich matrices. Furthermore, the development of novel functionalized sorbent materials has expanded the applicability of various solid-phase extraction formats, making them increasingly attractive within the framework of green analytical chemistry. It seems possible to extend these approaches to extract and cleanup the compounds of interest in other similar matrices as well.

The models were trained using features extracted from visible and near-infrared (VIS–NIR) hyperspectral data. Prior to classification, robust principal component analysis (rPCA) was applied for dimensionality reduction. Six principal component scores, which collectively accounted for 99% of the explained variance, served as the input features for the algorithms. By comparing the models using the sum of ranking differences (SRD), we aim to identify the most accurate approach for classifying wastewater based on BOD values. After comparing the results of the output models with preprocessed data, the performance on wastewater samples was deemed acceptable. The Logistic Model Tree (LMT) and Random Forest (RF) models (SRD = 0) delivered the best performance, with overall classification accuracy (CCI) of 95.3% and 96.51%, respectively. Both models also exhibited excellent ROC areas (0.99), low error rates (MAE: 0.04 for LMT, 0.09 for RF), and strong balance between TP and FP rates, confirming their superior reliability. Additionally, BN, SMO–SVM, and DT, with SRD = 4, 8, and 12 respectively, and a probability of randomness falling between 3.32 × 10⁻⁶% and 9.12 × 10⁻⁵%, exhibit acceptable performance.

These unique electrode catalyses the HER in addition to OER shows remarkable stability and efficient functioning in alkaline conditions. In contrast to the conventional reversible hydrogen electrode, the Cu₃Mo₂O₉/CdS nanoarray configuration greatly enhances the electrode’s ability to discharge hydrogen gas.

The high cost and operational complexity of gas sensors have led to the development of alternative materials. The ionic polymer metal composites, due to their unique sensing and biocompatibility properties, are evolving as important alternatives for the sensor materials. Nafion 117 is a type of IPMC, and the cost of Nafion 117-based E-sensors is relatively cheaper compared to other materials. The critical property of Nafion 117 for overall sensory performance coated with the neutral material makes it suitable to be used as a chemical sensor material for the investigation of food quality.
