Summary: In this study, halloysite nanotube (HNT) was used for efficient adsorption of malachite green and methyl violet 2B dyes from industrial wastewater. Various parameters affecting adsorption were optimized using batch adsorption experiments and response surface method. The results indicated that temperature had no significant effect on the adsorption process. Langmuir, Freundlich, Dubinin-Radushkevich, and Temkin isotherms well described the adsorption equilibrium data. The adsorption process followed pseudo-second-order kinetic model, and both intra-particle diffusion and film diffusion were important rate-determining steps. The adsorption was found to be exothermic and spontaneous thermodynamically. The regeneration of HNT was confirmed in five cycles. The Box-Behnken response surface method provided mathematical modeling of the adsorption process, enabling the determination of optimum operating parameters.

Summary: This study investigates the use of a new eco-friendly adsorbent made from motherwort biomass for the removal of crystal violet dye from aqueous solutions. The adsorbent exhibits high adsorption capacity and is influenced by various factors such as initial dye concentration, contact time, temperature, pH, adsorbent dose, and ionic strength. The adsorption process follows a general order kinetic model and is found to be endothermic, spontaneous, and favorable. pH is identified as the most influential parameter, contributing to 61.64% of the adsorption process. The findings demonstrate that motherwort biomass powder is a cost-effective, readily available, and effective adsorbent for crystal violet dye removal.

Summary: The study investigated the adsorption of U(VI) from natural mine water using sorbents modified by NH2 organic moieties in packed columns, finding that amine-functionalized SBA-15 was effective for U(VI) removal. Results showed that mesostructuration did not play a significant role in adsorption capacity, and the density of amine functional groups was crucial. Additionally, competitor ions such as Ca2+ and HCO3- were found to have a negative impact on U(VI) species adsorption on amino modified silica.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

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.
