Se estudia comparativamente varios procedimientos de extracción de plaguicidas 'en aguas, previo al análisis por cromatografia gaseosa y se concluye que para pequeñas cantidades de residuos de pesticidas organoclorados el procedimiento cuantitativo es la adsorción en columna de resina (Amberlita XAD-2).
Several techniques of extraction of pesticides from water, prior to the gas-chromatography analysis, have been studied. The results indlcate that for small quantities of residues of organochlorine pesUcides, the quantitative technique is the adsorption in column of Amberlite XAD-2 resin.
