以土壤微团聚体为对象研究重金属吸附的结果更接近田间实际状况,其结果作为预防和修复土壤的重金属污染的依据更有实际意义。对土壤微团聚体分组方法、分配比例以及微团聚体中有机质、铁铝氧化物的含量和表面电荷等基本性质进行了简要的综述,分别对微团聚体基本性质、pH和磷处理等因素对金属离子吸附的影响作了论述,进一步描述了微团聚体吸附重金属的动力学的研究进展,并对今后研究方向进行了探讨。
The study of the adsorption of heavy metals by soil micro-aggregates is closer to the actual situation in the field, and the results are more practical as a basis for prevention and remediation of heavy metal pollution in soils. The methods of soil microaggregate grouping, the proportion of soil microalgae, the contents of organic matter, iron and aluminum oxide and surface charge of microaggregate were briefly reviewed. The basic properties of microaggregate, pH and phosphorus treatment, The adsorption of metal ions is discussed. The progress of the study on the kinetics of the adsorption of heavy metals by microaggregates is further described. The future research directions are also discussed.
