Determination of chlorinated pesticide residues in drinking water by liquid-solid extraction and vacuum manifold system

摘要: Objective: The aim of this study is to determine the chlorinated pesticide residues in drinking water using a vacuum manifold system. Method: liquid- solid extraction method and GC/ µECD were used for determination pesticides water. Results: Chlorinated analysis are extracted from 1 L sample by passing through cartridge with C 18 organic phase. passed system at 4 mmHg pressure. This extract concentrated further evaporation. It was found that recovery values increased 53.7% 95.6%. precision 4.1% 19.8%. In calculating limit quantitation, standard deviation's numerical value which calculated each parameter experimentally multiplied 10. Analyzing the, Regulation on Concerning Water Indended Human Consumption permitted maximum residue limits Aldrin, Dieldrin, Heptaklor Heptaklorepoksid 0.03 µg/L it's 0.1 other parameters. reporting tested between 0.01 0.07 µg/L.
