| 摘 要： | 采用甘蔗残渣、丙烯酸(AA)、丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(MAETAC)为原料,通过接枝共聚反应制备出蔗渣基重金属离子吸附剂,对制备该吸附剂的影响因子如活化时间、蔗渣和单体的配比、引发剂用量、温度和时间等条件进行了分析研究,通过正交试验得到了合成吸附剂的优化工艺条件.优化条件下合成的蔗渣基吸附剂对Cu2+的吸附容量达到58.53mg/g,是蔗渣原料的12倍.

| Abstract: | The bagasse-based adsorbent was made from bagasse,acrylic acid(AA),acrylamide(AM),and[2-(methylacryloyloxy)ethyl]trimethylammonium chloride(MAETAC)through graft copolymerization.The factors affecting the absorption capacity,such as activated time,neutralization degree of AA,initiator dosage,initiator content were discussed in detail.The optimal preparation conditions were also obtained.The adsorption capacity for Cu2+of bagasse adsorbent made under optimized synthesis condition was 58.53 mg/g,which was 12 t... |
