英文摘要	Phosphate anion (PO43-) -responsive controlled release pesticide based on hydrogel (PCRPH) was developed based on crosslinking effect between ferric ion (Fe3+) and sodium carboxymethylcellulose (CMC). In PCRPH, attapulgite ( ATP) was served as carrier for loading imidacloprid (IM). The scanning electron microscope ( SEM) and X-ray diffraction (XRD) results demonstrated that PCRPH in PO43-- solution might swell and disaggregate, which could be enhanced as the PO43- contents in solution increase. As a result, the controlled-release of IM inside hydrogel could occur so that the utilization rate of pesticide was improved. According to the release kinetics analysis, the release mechanism of IM from PCRPH was consistent with the Fickian diffusion law. The release amount of IM from PCRPH remained stable against the coexisting Cl- and different pH, whereas temperature displayed positive relation with the release rate of IM.
