Title: Analytical Method of Residues for 6% Ascorbic Acid WA on Tobacco and Soil
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 average 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 determinations pesticide residues.
