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、用该硝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等温方程．
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.
