摘  要:
研究了橘皮作为吸附材料对含Cr(Ⅵ)废水的处理效果,对吸附剂用量、吸附时间、Cr(Ⅵ)溶液初始浓度及pH进行了优化。结果表明,在常温条件下,吸附时间为20 min、酸改性橘皮用量为6 g/L、Cr(Ⅵ)溶液初始浓度为7 mg/L、pH为2.0时,酸改性橘皮吸附效果更好,此时Cr(Ⅵ)的去除率可达98.14%。

摘  要:
Absorption effect of Cr6+ in wastewater by orange peel was studied.The absorption conditions including adsorption time,amount of modified orange peel,pH and initial concentration were optimized.The results showed that the best adsorption conditions were adsorption time,20 min;dosage of modified orange peel,6 g/L;pH 2.0;initial concentration of Cr6+ solution,7 mg/L;and room temperature.In this conditions the adsorption rate of Cr6+ could be up to 98.14%.
