Schiff base copper ion complex modified attapulgite (Cu2 -Sal-ATP) was prepared by post-grafting method. Acetamiprid loading into the pores of attapulgite(ATP) was performed by the immersion method. The modified Attapulgite were characterized by fourier transform infrared spectroscopy(FTIR), N2 adsorption-desorption, scanning electron microscopy(SEM), X-ray diffraction (XRD) and differential scanning calorimeter(DSC). The drug loading content and drug release kinetic were also systematically studied. The results showed that the loaded acetamiprid was apparently in amorphous form, and that the loading process did not change the structure of the carrier. The loading content of acetamiprid was increased with the organic modification of ATP, Cu2 -Sal-ATP has the highest loading content among the unmodified and organically modified ATP. The adsorption process for acetamiprid follows the pseudo-second-order kinetic model. The Cu2 -Sal-ATP/acetamiprid system exhibits better slow-release properties than schiff base modified ATP(Sal-ATP)/acetamiprid system, and their releasing curves could be described by Korsmeyer-Peppas equation.
