Abstract

Abstract:

The physicochemical properties of peat, a natural and cheap mineral, are introduced. The modifying methods of peat and its adsorption capacity for various heavy metals are reviewed. The influences of pH, modifying method, and concentrations of competing metals on peat adsorption are discussed. The adsorption mechanisms and rules of peat are summarized. The mechanisms of heavy metal ions binding to peat includes ion exchange, complexation, surface adsorption, and chemisorption. The sorption usually conforms to Langmuir isotherm or Freundlich isotherm. At the end, the application prospects of peat on the treatment of wastewater containing heavy metals are forecast, and some suggestions are proposed.

Key words: peat, heavy metals, wastewater

摘要：

介绍了天然廉价矿物泥炭的物理化学性质,综述了泥炭的改性方法及其对多种重金属离子的吸附容量,分析了pH、改性方法、竞争离子浓度等因素的影响。并对泥炭吸附重金属离子的机理和规律进行了总结,其吸附机理有离子交换、络合、表面吸附、化学吸附等四种,吸附一般符合Langmuir吸附等温式或Freundlich吸附等温式。最后展望了泥炭在重金属废水处理中的应用前景,提出了一些建议。
