| 摘 要： | 利用硝酸与龙口褐煤反应制得硝化褐煤，使其有效吸附质腐植酸含量提高。用该湖化褐煤对铬离子进行吸附试验，研究吸附剂的吸附量、吸附动力学、吸附模型和溶液的pH值对吸附的影响。结果表明：硝化褐煤对铬离子具有良好的吸附特性，其静态等温吸附符合Langmuir等温议程。

| Abstract: | The nitrify lignite is prepared from Longkou lignite with nitric acid, so that the effective ad-sorption of humic acid is increased. A test for the adsorption of chromium-ion with the nitrify lignite has been carried out. The capacities of lignite, adsorption kinetics, adsorption models and the ef-fect of pH were studied. The results indicated that the nitrify lignite had good adsorption properties to chromium-ion and the adsorption isotherms were consistant with Langmuir equation. |
