Abstract:A reversed phase HPLC was applied for determing the active ingredients of 30% Mefenacet-bensulfron-acetochlor mixed powder.Taking acetonitrile,methanol and water of 30∶40∶30 as the mobile phase at UV-230?nm ,SD and CV of the method for mefenacet, bensalfron and acetochlor are 0.038,0.15%,0.015,0.59% and 0.016,0.63%. The recovery is 98.1%~102.28%. |
Key words:HPLC; herbicide; mefenacet; bensulfron; acetochlor |
