用云南寻甸褐煤提取的腐植酸对Ni(Ⅱ )进行了吸附性能试验。试验研究了该腐植酸对Ni(Ⅱ )的吸附平衡时间 ,吸附速率 ,吸附量随pH值不同、初始浓度不同及吸附剂用量不同的变化情况。
The adsorption properties of Ni (Ⅱ) with humic acid extracted from Yunnan Xundian lignite were tested. The adsorption equilibrium time, adsorption rate, adsorption capacity of humic acid on Ni (Ⅱ) were studied experimentally with different pH value, initial concentration and amount of adsorbent.
