Design of an Eco-Friendly Ag₂O/AC New composite for Wastewater Remediation via Dual Adsorption and Oxidation to Maximize Organic Pollutant Degradation in Industrial Effluents
Main Article Content
Abstract
This work prepared new composite (Ag2O/AC) used as adsorbent and oxidation from activated carbon (AC) prepared from Upholstery waste (UW) by carbonization and precipitation methods by hydrated 5% silver nitrate (AgNO3) by Photo Oxidation Batch Reactor (POBR) to organic elimination from refinery wastewater (RWW) through a batch technique and compared between them on activated carbon. The FTIR, FE-SEM, EDX and BET analyses were used to characterize the physicochemical properties of the AC and Ag2O/AC samples. The removal efficiency of organic contaminants was inspected under four working conditions: dose (0.2-1 g), pH (3-9), agitation speed (100-300 rpm), and contact time (30-120 min). The removal efficiency under various working conditions was studied to assess the surface efficiency of organic removal on prepared activated carbon and new composite and compare them with the largest organic removal efficiency were 99.6 % and 74.6 % of Ag2O/AC and AC at 1 g, pH 3, 300 rpm and 120 min respectively, obtained with Ag2O/AC, which presented a superior adsorption efficiency for organic removal in refinery wastewater.
