摘　　要：采用FeSO_(4)改性综合开发后的柚皮残渣,开展水体六价铬Cr(Ⅵ)吸附研究,探讨吸附剂添加量、吸附时间、吸附温度、废水pH值及废水Cr(Ⅵ)初始浓度对吸附效果的影响。静态吸附实验结果表明,当废水Cr(Ⅵ)含量为50 mg/L时,综合考虑成本及GB 8978—2002污水综合排放标准,最佳吸附条件为:吸附温度为20℃,废水pH值为2,吸附剂添加量为10 g/1 L,吸附时间为60 min,此时Cr(Ⅵ)的去除率和吸附量可分别达99.05%和4.95 mg/g。The pomelo peel were comprehensively utilized and the residue modified by FeSO_(4) were used to carry on the research on the Cr(Ⅵ) in water.Affecting factors on the adsorption including adsorbent dosage,adsorption time,pH value,reaction temperature and initial concentration of Cr(Ⅵ) were investigated.The result of static adsorption experiment showed that under the optimum conditions,reaction temperature of 40 ℃,pH of 2,adsorbent dosage of 10 g/L and adsorption time of 60 min,the removal rate and adsorption capacity of Cr(Ⅵ) were 99.05% and 4.95 mg/g respectively,considering the economic cost and relevant standards.
