JIANG Zhibin(Lian Yun -gang Technical College, Lian Yun-gang, Jiangsu 222006, China)
This paper proves that by determinating chromatopyrography, there is no difference in the remainder of pesticides between fresh tea and finished tea leaves containing eight isomers including hexachloran and DDT at the same place. The determination limit in this way is 1. 8ng/g, rate of return ranges from 78. 2% -99. 0%, and its relative standard windage is 10. 0%.
