ABSTRACT
Objective To establish a method for simultaneous determination of kelthane and pyrethroid pesticide residues in water.Methods Kelthane and pyrethroid pesticide residues in the water were extracted by liquid-liquid,then analyzed with DB-1 capillary column.In the same time,they were determined with GC by controlling the temperature.Retention time of the peaks was used for qualitative analysis,while external standard method was used for quantitative analysis.Results The linear ranges of Kelthane,Bifenthrin,Fenpropanate,Lambda cyhalothrin,Permethrin,Beta cyfluthrin,Alphacypermethrin,Fenvalerate were 0.24-31.1,0.21-27.2,0.20-26.0,0.21-26.5,0.20-25.7,0.21-26.4,0.22-29.0 and 0.22-27.4 ?g/L,r≥0.999 0.The lowest determination limits were 0.20,0.33,0.30,0.13,0.36,0.26,0.33 and 0.30 ?g/L,the rate of recovery was 86.0%-111.7% and RSD was 3.8%-11.8%.Conclusion This method can separate efficiently and determine 8 kinds of pyrethroid pesticide residues in the water and only needs 23 minutes.It's simple,rapid and sensitive.
