摘　　要：采用ZnCl_(2)改性茶枝以改变其原有的结构增加其吸附性能,并探讨改性剂浓度、时间、温度等对改性茶枝活性炭吸附性能的影响。结果表明,改性茶枝对水中的NH_(4)-N模拟废水吸附效果好。当改性茶枝0.10 g,质量浓度40 mg/L的氨氮溶液100 mL,温度40℃、pH为8时,振荡40 min的条件下,去除效率最好。Tea bar carbon was modified by ZnCl_(2) to change its structure for increasing adsorption capability.The influences of the initial concentration,adsorption time and temperature on modified tea bar carbon were studied.The results showed that the removal effect of NH4-N was the best under the following conditions:adsorbent dosage:0.10g;NH4-N concentration:40 mg/L;temperature:40℃;pH:8;adsorption time:40 min.
