An improved extraction method for the quantitative analysis of pesticides in water.
An improved method for enrichment and analysis of chloropesticides (5), triazines (1, 4, 6), phosphoric acid esters and other compounds by a rotation perforator according to Ludwig (2, 3) is presented. Water fortified with pesticides was analysed according to this procedure. The organic extract was quantified by gas chromatography. The recovery rates ranged from 80% to more than 110%, whereas those compounds sensitive to hydrolysis and oxidation were insufficient. The above described method was applied to surface water and groundwater analysis.
