Abstract:
Objective To develop an HPLC analytic method for determination of cyromazine residue in water.Methods Chromatographic column of YMC C18(150 mm?4.6 mm,5 ?m)was used,mobile phase was methanol+0.02 mol/L NH4Ac=15+85(V/V),flowing rate was 1.0 ml/min,DAD detection wavelength was 210 nm.Results Regression equation was y=243.8x-4.2,r=0.999 96.The minimal detectable concentration was 0.010 mg/L;the rate of recovery was 94%-100% and the relative standard deviation was less than 3.0%.Conclusion The method is satisfactory in precision,accuracy and sensitivity.
