生物吸附法是一项处理重金属离子废水污染的新技术,在处理重金属污染废水和重金属回收方面有着广阔的应用前景,具有较好的经济价值和社会效益。本文主要研究改性笋壳为吸附剂去除废水中的铬离子,探讨振荡时间、吸附剂量、初始浓度、温度、pH对铬离子去除率的影响。结果表明：pH对铬离子去除率有很大影响,pH越低,吸附效果越好。当笋壳用量为0.5 g,、振荡时间为90 min,铬离子吸附率可达40%以上。

Biosorption is a new, cleaner technologies of heavy metal ions in wastewater treatment, in dealing with wastewater of heavy, metal and recovery of heavy metal pollution has a wide application prospect, and has good economic value and social benefits. This paper studies modified bamboo shell as an adsorbent of chromium ions removal from wastewater, discussing the effect of shaking time, adsorbent dosage, initial concentration, temperature and pH on the removal of chromium ion. The results shoved： pH has a great influence of the chromium ion removal, pH lower, the better the absorption effect. When the bamboo shell dosage O. 5 g, shock time was 90 min, the removal rate of chromium is 40%.
