Summary: A new type of composite material, biopolymer-silica materials, is proposed as selective and effective adsorbents. A new synthesis procedure using geometrical modification of silica and mechanosorption of chitosan is applied to create chitosan-nanosilica composites (ChNS) and chitosan-silica gel composites (ChSG). The adsorption efficiency of ChNS and ChSG towards anionic dyes was analyzed and the results showed that ChNS had faster adsorption kinetics due to the silica-type effect.

Summary: Given the large amount of harmful pharmaceuticals being released into the water stream, it is crucial to eradicate or reduce these chemicals to a minimum permissible limit. This study reports the fabrication of a magnetic guar gum graphene oxide nano-composite (mGG/GO NC) for the adsorption of ciprofloxacin from wastewater. Various techniques were used to characterize the guar gum and the nanocomposite, and it was found that the adsorption process followed the pseudo second order model and Langmuir isotherm model. The nanocomposite exhibited high adsorption capacity and recyclability, potentially due to a synergistic effect of multiple interactions in the adsorption mechanism.

Summary: The waste effluents of textiles and leather industries, which contain organic dyes as major contaminants, have been found to cause serious health problems. Adsorption techniques using mesoporous silica nanoparticles (MSNs) were investigated for the efficient removal of organic dyes from industrial wastewater. The MSNs were synthesized with selectively generated active inner/external surfaces by incorporating functional groups through co-condensation and post-grafting procedures. The study evaluated different grafting strategies and their effectiveness in removing cationic dye (methylene blue) from contaminated water samples. The results showed that nanomaterials containing sulfonic acid exhibited the highest adsorption performance, with an extraction efficiency of 98%. Increasing the salt concentration in the water samples improved the adsorption efficiency of all the nanomaterials.

Summary: The removal of reactive red M-2BE dye from aqueous solution using multi-walled carbon nanotubes and powdered activated carbon was studied. Machine learning algorithms were used to model the kinetic adsorption, and the SHapley Additive exPlanations (SHAP) were employed to interpret the effect of each feature on the adsorption capacity. The results showed that the ANFIS model had the best statistical metrics, and temperature had the least contribution in describing the adsorption capacity. This novel application provides important insights for adsorption research.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
