Summary: The study focuses on the adsorption efficiency of new carbon/CNT composites in removing Rhodamine B dye from dye-contaminated wastewater. The presence of carbon nanotubes increases the active sites for dye removal and improves the adsorption behavior. The Freundlich isotherm model is the best fit for the experimental data, and the mechanisms for dye removal using carbon composite are predicted.

Summary: A new porous organic polymer based on triazine and cyclohexanone rings was synthesized and investigated for its adsorption performance in removing Methyl Red dye from aqueous solution. The optimized adsorption conditions were determined to be pH 4, contact time of 80 min, adsorbent dose of 8 mg, initial dye concentration of 50 mg/L, and temperature of 45 degrees C. The adsorption process followed the Langmuir isotherm and pseudo-second-order kinetic, indicating monolayer adsorption and the importance of chemical interactions in dye removal. The maximum adsorption capacity achieved was 178.57 mg/g, and the adsorption process was found to be endothermic.

Summary: This study investigated the use of chemically synthesized apatite (CHAp) powder as an adsorbent for removing Cd2+ from water. The effects of time, initial Cd2+ concentration, amount of CHAp, temperature, and solution pH on the adsorption process were studied. Various analytical techniques were used to analyze the synthesized hydroxyapatite (HAp) powder and confirm its adsorption capacity. The results showed that CHAp performed well as an adsorbent for Cd2+ and could be used in bioremediation applications.

Summary: Adsorption of sulfonamides (SAs), specifically sulfamethoxazole (SMX) and sulfamethazine (SMZ), from aqueous solution using carbon nanotubes (CNTs) was investigated. The study examined the effects of contact time, solution pH, CNTs dosage, initial SA concentration, and temperature on the adsorption process. The kinetics was simulated using pseudo-first-order, pseudo-second-order, and intraparticle diffusion models, while the equilibrium behavior was modeled using Langmuir and Freundlich isotherms. The adsorption of SAs onto CNTs followed the pseudo-second-order and Langmuir models. The adsorption amount increased with increasing pH, CNTs dosage, and temperature, while it decreased with increasing initial SAs concentration. The study also provided insights into the hydrophobic and electrostatic interactions involved in the adsorption process, as well as the significance of octanol-water partitioning coefficient (Kow) and pH in these interactions. The thermodynamic analysis suggested that the adsorption of SMX and SMZ onto CNTs was a spontaneous physisorption process.

Summary: This review critically investigates the effect of using microwave heating technique on the morphology, surface chemistry, and pore structure of Carbon based, minerals and polymeric adsorbents, as well as the adsorption performance of water pollutants using microwave synthesized adsorbents. Competitive comparisons between adsorbents prepared by microwave and conventional heating techniques are discussed, along with suggestions for future development of microwave prepared adsorbents for water pollutants removal. Further development and investigation are still required for using microwave technology in adsorbents preparation.

Summary: In this study, the removal of dye ADMI from raw textile wastewater was investigated using magnetic multi-walled carbon nanotubes-loaded alginate. The key factors, including pH, adsorbent dose, and contact time, were optimized using response surface methodology-based central composite face-centred design. The adsorbents were characterized using various techniques. The developed model fit well with the experimental data, and under the optimized conditions, a high removal efficiency and ADMI adsorption capacity were achieved. The adsorption process was found to be monolayer and chemical in nature. The adsorption mechanism could be explained by the presence of negatively charged carboxyl and hydroxyl groups on the surface of the adsorbent.

The optimal conditions included solution pH in the range of 5-8, catalyst dose below 600 mg/L, diazinon initial concentration below 40 mg/L, and contact time of 20-140 min. Diazinon degradation followed a first-order kinetic model.

Summary: This study aimed to develop a rapid and cost-effective laboratory method for modeling and optimizing chlorine disinfection conditions. The results showed that optimization of disinfection factors had a significant effect on planktonic cells of P. aeruginosa but not on the biofilm. The concentration of NaOCl and CAT was more effective than pH in inactivating planktonic and biofilm cells. However, the use of chlorine compounds based on recommended levels did not prevent the formation of P. aeruginosa biofilm.

Summary: The cardiovascular benefits of particulate-filtering respirators (PFRs) remain unclear. A systematic review and meta-analysis of randomized studies were conducted to evaluate the effects of wearing PFRs on blood pressure and heart rate variability. The analysis showed modest or non-significant improvements in blood pressure and some heart rate variability parameters from wearing PFRs over short periods. However, these findings are limited by the small number of trials and variations in experimental designs and durations.

Summary: This systematic review investigates the relationship between exposure concentrations of organophosphate esters (OPEs) in outdoor air and health risks, as well as correlations between OPE compounds in emission sources. The review identified 46 relevant studies and found that TCIPP, TMPP, TiBP, TPHP, and TCEP had the highest concentrations of OPEs overall. Principal component analysis revealed that F1 and F2 accounted for 49.81% of the cumulative contribution. The EDI values showed that TCEP, TCIPP, and TMPP posed the highest non-carcinogenic risks, and TCEP and TMPP had the highest carcinogenic risk values.
