| Abstract: | Analytical method of residues for 6% Ascorbic Acid WA was established on tobacco and soil. The minimal determined quantity is 2.0×10^-8g. The results showed that the recoveries were found to be in the aver- age range of 94.0% to 95.1% with the relative standard deviations （RSD） of variation from 5.0% to 9.0% for plant samples, when the additive amount was 0.1 mg/kg, 1.0 mg/kg, 10.0 mg/kg, and the recoveries were found to be in the range of 90.0% to 98.4% with RSD of variation from 2.3% to 7.4% for soil samples. The sensitivity, accuracy and precision of the determination method accords with the technological standard of deter- minations pesticide residues. |
