| Abstract: | An RP-HPLC method for the qualitative determination of herbicide difenzoquat was developed. Operating conditions were UV-254 nm detection, Selectosil 5 C18 column 250 mm x 4.6 mm i.d., and V(methanol):V(water) = 60:40 (pH3, adjusted by H3PO4) as mobile phase. The coefficient of variation of this method was 0.41% with recoveries from 98.71% to 100.36%. The retention time was about 6.6 min. The coefficient of linear correlation was 0.9999. The method is very effective for the quality control of SP (water soluble power) products of this pesticide. |
