摘　　要：泥炭经硝化和磺化处理后对重金属离子Pb2+、Zn2+的单组分溶液进行了吸附实验,讨论了影响吸附的因素。研究结果表明;硝化泥炭、磺化泥炭对Pb2+、Zn2+重金属离子有好的吸附,以磺化泥炭效果较好,其吸附规律基本符合Langmuir方程。Nitrifying and sulphonated peat separately with solution containing Pb^2＋ were studied The factors affecting adsorption were determined. The results showed that nitrifying peat and sulphonated peat had a good adsorption effect on Pb^2＋ and Zn^2＋ , and the effect of sulphonated peat was better. Their adsorption law accords with the langmuir equation on the whole.
