Preparation and Characterization of Bifenthrin Nanoemulsions
摘要
Abstract
[ Objective] The paper was to prepare bifenthrin nanoemulsions, and to characterize its property. [ Method] Oil in water type of ffenthrin nanoemulsions was prepared using emulsion phase inversion method at constant temperature of 25 ℃. The formation mechanism of nanoemulsions was investigated, and the property of bifenthrin nanoemulsions was characterized by dynamic light scattering(DIS), transmission electron microscopy (TEM), contact angle instrument, interffacial tension instrument and high performance liquid chromatography (HPLC). [ Result ] Phase inversion occurred during the formation progress of bffenthrin nanoemulsions; the particles of nanoemulsions system was sphere, and the particle size was mainly distributed in a range of 25 -30 nm; the contact angle on paraffin was less than 90° with good moist effect; the inteffacial tension was less than 40 mN/m, and the emulsification effect was also good, so the utilization efficiency of bifenthrin nanoemulsions was improved. HPLC results showed that bifenthrin was not easy to decompose or precipitate with good stability.[ Conclusion] The result provided basis for the preparation of new type of insecticides.关键词
