| Abstract: | A method was established for determination of carbofuran,carbaryl and atrazine in water samples by solid phase extraction（SPE） and high performance liquid chromatograph（HPLC） using methanol-water as the mobile phase with gradient elution.The detection was made on a diode array detector at 220 nm.Dichloromethane was selected as eluting solvent.The results indicated that the good linear ranges were 0.200 mg/L～5.00 mg/L for carbofuran,and 0.020 mg/L～5.00 mg/L for carbaryl and atrazine.The detection limits of the method were 0.24 μg/L,0.019 μg/L and 0.035 μg/L for carbofuran,carbaryl and atrazine,respectively.The average recoveries of spiked standard materials at two quantity levels were from 84.0 % to 103%,and RSD was from 1.6% to 8.5%. |
