摘要
研究了碳纳米球对水溶液中镉离子的去除性能。结果表明,水溶液中镉离子去除率随着振荡时间的增加、初始浓度的减小、碳纳米球用量和溶液初始p H值的增大而增加。吸附平衡时间为300min;去除率随着温度的升高而降低,表明此吸附过程为放热反应。
The adsorption property of carbon nanosphere for Cd2 ＋from aqueous solution was investigated in the paper. The experimental results showed that the removal rate of Cd2 ＋increased with rising agitating time,carbon nanosphere mass and p H,decreasing Cd2 ＋initial concentration. The adsorption equilibrium time is 300 min. The removal rate decreased with temperature increment,suggesting the adsorption is exothermic.
