摘要
利用NaClO对多壁碳纳米管进行化学改性处理,考察了改性剂加入量、改性温度、改性反应时间等因素对改性效果的影响。利用改性后的多壁碳纳米管为吸附剂处理含苏丹红Ⅰ的废水,考察了苏丹红Ⅰ初始浓度、吸附剂加入量、吸附反应温度及吸附反应时间对苏丹红Ⅰ去除效果的影响。结果表明:改性后的多壁碳纳米管对苏丹红Ⅰ显现出了良好的去除效果,去除率最高达到了92.4%。
The multi-walled carbon nanotubes were chemically modified by NaClO.The effects of modifier addition,modification temperature and modification reaction time on the modification are investigated.The modified multi-walled carbon nanotubes are used as absorbent to treat Sudan Red I containing wastewater.The effects of initial concentration of Sudan red I,absorbent addition amount,absorption reaction temperature and absorption reaction time on the removal of Sudan Red are investigated.The results show that modified multi-walled carbon nanotubes show good removal effect on Sudan Red I,and the removal rate reaches 92.4%.
