摘  要：
粘土可与多种阳离子发生离子交换,制备具有不同吸附性能的改性粘土。后者作为农药控制释放载体,可适用于各类性质和用途不同的农药,从而提高农药利用率,控制农药污染。通常,改性粘土对农药的吸附作用越强,农药释放越慢。将改性粘土与天然水溶性高分子一起制备复合农药载体,有利于提高载药能力,进一步拓展应用范围,强化对农药释放过程的调控作用。

摘  要：
Modified clays with various adsorption capacities to pesticides were prepared by ion exchange with various cations.They had been used for the controlled release of pesticides with various properties and applications,so as to improve their utilization efficiency and to control their potential pollution to environment.The modified clays with higher adsorption capacity generally resulted in the slower release of pesticides.The modified clays were also used with natural water-soluble polymers together for the preparation of composite carriers.In this way,the loading capacity of pesticides onto the carriers was improved,the carriers' applications were extended,and the release of pesticides was better regulated.
