The present investigation describes the use of bioadsorbent, ozonolysis, and integrated process (ozone integrated with bioadsorbent) treatment for leather industrial dye (Acid Yellow 2GL) removal from simulated wastewater. The morphological characterization of agriculturally based, chemically activated bioadsorbent was presented using SEM, FTIR, XRD, and BET analysis which suggested the high potential of the adsorbent for the removal from leather industry effluent. Maximum Acid Yellow 2GL removal of 98.3 ± 2.3% by integrated treatment was achieved at 30 min, bioadsorbent dose of 3 g/L and pH 7.5. Adsorption isotherms and kinetic models were measured for the validation of bioadsorption process for removal of dye. Langmuir’s isotherm was best fitted for Acid Yellow 2GL dye sorption in comparison to Freundlich isotherm. The phytotoxicity analysis of treated effluent ensured that the integrated process could be a prospective candidature for the treatment of dyeing effluent from the leather industry.

本研究描述了使用生物吸附剂、臭氧分解和集成工艺（臭氧与生物吸附剂集成）处理从模拟废水中去除皮革工业染料（酸性黄 2GL）。使用 SEM、FTIR、XRD 和 BET 分析展示了农用化学活化生物吸附剂的形态特征，表明该吸附剂具有从皮革工业废水中去除的巨大潜力。在 30 分钟、生物吸附剂剂量为 3 g/L 和 pH 值为 7.5 时，通过综合处理实现了 98.3 ± 2.3% 的最大酸性黄 2GL 去除率。测量吸附等温线和动力学模型，以验证去除染料的生物吸附过程。与 Freundlich 等温线相比，Langmuir 等温线最适合酸性黄 2GL 染料吸附。
