This Study focuses on the preparation of sustainable and efficient Chitosan catalyst for removal three organic pollutants, 17β-Estradiol (E2), 17α-ethynyl estradiol (EE2) triclosan (TCS) from water. The prepared nanocomposites were characterized by different techniques which confirmed presence key components Chitosan, Carica Papaya seed Kaolinite. optical characterization proved nanocomposite is photoactive with a band gap 1.81 eV 1.77 Chitosan/kaolinite biochar (CS/KBC) biochar/GO (CS/KBC/GO) respectively, confirming ability to be active in visible light region spectrum. degradation experiment using CS/KBC/GO was observed better 100% 5 mg/L E2 EE2 over 60 min 97.8% 120 10 TCS at optimum conditions (pH 3 E2, pH 7). It that superoxide radical played major role contaminants. Furthermore, four cycles without any decrease performance, rules out question deactivation proving sustainability catalyst. toxicity test shows water safe as it does not harm cerio daphnia silvestrii organism.; efficiently removed micropollutants real-life waste samples performance very good slight wastewater due complex matrix sample competes site.
