摘　　要：研究甲醛改性的橙皮对Cr6+的吸附作用,并探讨溶液的pH值、Cr6+初始浓度、吸附时间及温度等因素对Cr6+吸附效果的影响。结果表明,经甲醛改性的橙皮对Cr6+有很好的吸附作用,在温度60℃,10 mg/L的Cr6+溶液50 mL,溶液pH值为1.0,甲醛改性的橙皮用量为12 g/L,振荡时间为100 min的条件下,Cr6+的吸附率达到了99.76%。Adsorption of Cr^6＋ by modified flavedo was studied.The effects of pH,initial Cr^6＋ concentration,contact time and temperature on adsorption were investigated.The results indicated that modified flavedo had good adsorption effitient to Cr^6＋.In condition of 60 ℃,12 g/L modified flavedo,50 mL 10 mg/L Cr^6＋ solution,the initial pH of 1.0,contacting 100 min,the adsorption rate of modified flavedo to Cr6＋ could be up to 99.76%.
