Résumé

Dyes are responsible for major environmental issues globally due to their toxicity, large-scale production, and extensive use in various industrial sectors. Pollution caused by hazardous dyes is mainly textile waste, which constantly discharged into the aquatic system, often causing harm humans affecting water quality. In recent years, removal of from wastewater has been a challenge. Numerous technologies methods have developed remove meet clean requirements. this study, effectiveness activated carbon prepared chemical activation jujube stones treatment was investigated. The effects concentration H3PO4 carbonization temperature on carbon’s properties were studied. Several physicochemical methods, including Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction, methylene blue index, Boehm titration, iodine index pH point zero charge, considered characterize produced adsorbents. To assess quality two studied effluents (Mustard Violet), following parameters used: biological oxygen demand (BOD), (COD), turbidity, suspended particles dissolved solids, before after with carbon. Untreated analysis revealed high values almost all parameters: andgt
