摘　　要：泥炭经硝化或磺化处理后对重金属离子Pb2 + 、Cu2 + 的单组分溶液进行吸附试验 ,讨论了影响吸附的因素。结果表明 ,硝化泥炭、磺化泥碳对Pb2 + 、Cu2 + 重金属离子有很好的吸附性 ,以磺化泥炭吸附效果较好 。A group of experiments have been done with nitrifying and sulphonated peat separately with solution containing Pb 2+ and that containing Cu 2+ ,and there is a discussion about the factors affecting absorption.The results showed that nitrifying peat and sulphonated peat have a good absorption effect on Pb 2+ and Cu 2+ ,and the effect of sulphonated peat was better.Their absorption law accords with the Langmuir equation on the whole.
