Determination of Flufiprole and Its Metabolites in Samples From Paddy Field
摘要
Abstract
A method using solid-phase extraction and gas chromatograph-microelectron capture detector ( GC - ECD) was developed to detect flufilprole and its metabolites in plant, soil and water in paddy fields. Water samples were extracted with methylene chloride, soil samples first with acetone and then with ethyl acetate and plant samples first with acetonitrile and then with CarbonNH2 and at the end cleaned up with solid phase extraction (SPE) for analysis with GC - ECD. Results of the analysis show that the lowest content of pollutants detected was 0. 01 mg ? L-1 in the water and 0. 015 mg ? kg"' in the soil and the plant. When 0. 05 - 1. 0 mg ? L-1 (or mg ? kg-1) of the pollutants were added into the field, the recovery rate of using this method was in the range of 75. 1% - 109. 2% with variation coefficient being 1. 0% -7. 9%. This method is simple, accurate, and readily applicable in the analysis of paddy field samples.关键词
