摘要

This study reports the optimized production of zeolite from a cheap agricultural waste material (sugarcane bagasse) using alkali fusion method, thereby studying four key variables: contact time, temperature, particle size and reagent ratio in full factorial design matrix. Following a thorough characterization of the produced zeolite, the adsorption of 2-chlorophenol in an aqueous matrix by the zeolite was also optimized using four variables: pH (6–8), contact time (90–150 min), sorbent dosage (1–4 g), and temperature (30–60 °C). At pH 8, temperature 60 °C, contact time 90 min, and 1 g adsorbent dosage, the optimal adsorption of 78.2 mg/g of 2-chlorophenol was accomplished. The kinetic and equilibrium data were best described by pseudo-second-order and Freundlich models respectively. Additionally, the optimized zeolite demonstrated stability during three regenerative cycles. These results highlight the potential of the optimized zeolite produced from sugarcane bagasse as an excellent material for 2-chlorophenol removal from wastewater. This study, therefore, provides an economically sustainable remedy for water contamination by producing zeolite from cost effective sugarcane bagasse. It helps environmental cleanup and enhances industrial sustainability via its applications in water treatment and chlorophenol removal, which promote waste recycling and environmental preservation.
