Abstract:
Objective To establish a SPE-HPLC method for the determination of carbaryl and atrazine in water.Methods Carbaryl and atrazine in water were extracted with Oasis HLB and were eluted with CH3OH,CH3OH-H2O(55:45) was applied as mobile phase,the flow rate was 0.8 ml/min,detection wavelength was 220 nm,column was Symmetry Shield RP18(150 mm ? 3.9 mm,5 ?m),carbaryl and atrazine in water were determined by PDA detector.Results The linear range of the method was 0.05-10.0 mg/L(y=316 263x-350 9,r=0.999 9,for carbary;y=140 151x-258 6,r=0.999 9,for atrazine),The lowest detected concentration was 0.0002 mg/L for carbary and 0.000 5 mg/L for atrazine,respectively(S/N≥3).The recovery rates were 89.6%-97.0%,and the relative standard deviation was 4.0%-6.7%.Conclusion The method was sensitive,accurate and repeatable,which was applicable to the determination of carbaryl and atrazine in water.
