【Abstract】 In this study the coacervation-phase separation procedure using aqueous vehicles was applied in the microencapsulation of fenitrothion successfully. The result showed that an excellent microencapsulation state could be achieved when pH value was adjusted gradually, the releasing process of fenitrothion from microcapsules would be slowed down when more wall-harding agent was added; the surface average diameter (Ds) would be reduced when more emulsifier was added; and the shoot phenomenon would be prevented sucessfully with the addition of CMC (Carboxy Methyl Cellulose).更多还原
