摘要
采用吸附法去除水体中重金属锰,以NaOH对天然沸石改性,对含Mn的水体进行处理,通过单因素实验系统考察了改性沸石用量、吸附时间、初始浓度、温度对吸附效果的影响,研究结果表明在25℃,吸附剂用量为1.0 g,吸附时间120 min,对初始浓度为1.0 mg/L时,锰的去除率可达到99.3%,最大吸附容量达到9.93 mg/g。
The removal of heavy metal manganese from water with adsorption method was studied. NaOH was used to strengthen its absorption of natural zeolite, and treated with a body of water containing manganese. The use of single-factor experiments systematically investigated these fac- tors effect of adsorption, such as the amount of modified zeolite, adsorption time, initial concentration and temperature. The results showed that at 25 ℃, adsorbent dosage of 1.0 g, adsorption time 120 min, the initial concentration of 1.0 mg/L shoved removal rate reached 99.3%, the maximum adsorption capacity of 9.93 mg/g.
