UF-resin was used to encapsulate chlorpyrifos via in-situ polymerization.The factors affecting the morphology and the encapsulation efficiency of the microcapsules were investigated,and the drug loading was also determined.The results show that at a heating rate of 0.5℃/min,a stirring speed of 20 r/min and with 0.4% sodium chloride added in the solidifying period,microcapsules with good shape could be prepared.Different core/wall ratios did not significantly affect the encapsulation ratio,and the encapsulation ratios for 12,15,18,21 and 24 g UF-prepolymer solutions were 98.56%,98.89%,99.34%,98.25% and 98.21%,respectively.However,acidification and solidifying time could affect encapsulation ratio evidently,and the optimum periods of acidification and solidifying were 60 min and 100 min respectively.The drug loading ratio of the microcapsules was as high as 0.642 g/g.
