以改性有机肥为吸附剂吸附水中Cu(Ⅱ),探究了Cu(Ⅱ)初始浓度、吸附时间、吸附温度、吸附剂用量、转速和溶液初始pH值等因素的影响。结果表明,pH=5、温度30 ℃、转速150 r /min时,改性吸附剂吸附Cu(Ⅱ)在2 h达到吸附平衡;吸附剂用量为8 g /L时,吸附量最大;吸附过程符合准二级动力学方程,等温吸附曲线符合Langmuir方程,说明其吸附为单层吸附。

Test on removal of Cu(Ⅱ) in the water by using a modified organic fertilizer as a adsorbent was performed,and influences of initial concentration of Cu(Ⅱ),adsorption time and temperature,adsorbent dosage,rotating speed of agitator,as well as initial pH value of solution,on the removal effect were investigated.Results showed that with pH at 5,rotating speed at 150 r /min for the agitator,the adsorption of Cu(Ⅱ) by such modified adsorbent at a temperature of 30 ℃ reached an equilibrium after 2 h.And the adsorption reached the maximum with the...
