农药在土壤－水环境中归宿的主要支配因素──吸附和脱附

One of the most important factos affecting the fate of pesticide in soil-water environmental:sorption and desorption

综述了近年来农药在土壤－水环境中吸附－脱附研究的实验方法、影响因素、数学描述、作用机理等方面的工作。重点讨论了农药与土壤粘土矿物、有机物（腐殖酸、富菲酸等）的物理化学键合机理。

This paper reviews on the the most important factors affecting the fate and behaviour of pesticide in soil-water environmental(sorption and desorption).The experimental methods,methematical modelsand interaction mechanisms,involing ionic,hydrogen and covalent bonding, chargetransfer or electron donor-acceptor mechanisms,Van der waals forces,ligand exchange and hydrophobic or partitioning are included.
