| 摘 要： | 褐煤经磺化和碱化处理对褐煤吸附重金属的性能影响显著，通过对金属离子Ｃｕ＾２＋，Ｐｂ＾２＋，Ｚｎ＾２＋，Ｃｄ＾２＋，Ｎｉ＾２＋的单组分或多组分溶液进行吸附研究，对比了吸附速率、吸附容量、吸附选择性、耐酸性以及抗干扰能力等方面的差异，探讨了磺化褐煤和碱化褐煤对重金属离子的吸附机理，指出了今后的研究方向。

| Abstract: | The lignite was activated by sulphonation or alkalization. The adsorption characteristics of Cu2+ , Pb2 + , Zn2 + , Cd2+ , Ni2+ ions on the activated lignite were studied. The adsorption rate, isotherms, capacity and the effects of some factors such as pH, Ca2 + ion and EDTA were characterized separately. Results showed alkalization for lignite was a simple and effective method for preparing adsorbent of heavy metal ions. |
