|
|
The simultaneous determination method which simply determined regulated pesticides was investigated. Sample was extracted with acetone-methanol and partitioned with methylene chloride after addition of saturated NaCl solution. Entract was purified by Bio-Beads S-X3 column using cyclohexane-methylene chloride (1 : 1) as eluate. The determination of pesticides was performed by BP-1 capillary column gas chromatography using ECD and NPD. The average recoveries of pesticides in rice and soy fbean were over 83% and 81%, respectively. It was possible to detect pesticides in rice up to 0.002 ppm by α-BHC and up to 0.05 ppm by carbaryl and in soy bean up to 0.01 ppm by α-BHC and up to 0.3 ppm by carbaryl.
