In this study, double dehydration of sorbitol into isosorbide using commercial sulfonic acid resin as a catalyst was carried out under vacuum conditions generated by water ejection. To improve the efficiency and selectivity process, optimum reaction prescribed temperature, loading, time were investigated Box-Behnken design (BBD) together with Response Surface Methodology (RSM). The results showed that ejection system could increase activity. Statistically, all parameters found to significantly affect response, including conversion, 1,4-sorbitant yield, yield. Furthermore, accurate predictive equations for responses displayed R2 > 95 %, no significant errors observed. optimized resulted in complete conversion 6.42 % yield 67.55 yielded predicted values minor variances being lower than 1 when compared experimental values. However, decreased steadily over recycling cycle due reduced active sites textural properties, likely caused structural collapse by-product accumulation. This work contributes biomass valorization optimizing effective process production via catalysts conditions.

The electrochlorination (E-Cl) process has attracted much attention as it is a highly efficient method for treating organic compounds in hypersaline wastewater. In this study, the E-Cl was utilized removal of antibiotics. optimal experimental conditions were determined to be NaCl concentration 100 mM, current density 1.5 mA/cm2, pH 7.0, and plate spacing 1 cm, with levofloxacin (LEV) degradation efficiency reaching high 99% using setup. effects presence other ions humic acid on investigated, found that LEV not significantly affected by coexisting substances. addition, free chlorine identified primary active species means quenching experiment. It demonstrated 3D EEM TOC completely mineralized intermediate products may present. order reveal pathways LEV, its also analyzed via LC-MS, some possible system proposed. successful an promising technique treatment pollutants high-salinity
