Isolation of chlorophenoxy herbicides on columns of glass beads


, : Isolation of chlorophenoxy herbicides on columns of glass beads. Journal of Association of Official Analytical Chemists 60(6): 1324-1327

A method for the analysis of chlorophenoxy herbicide residues was developed based on the observed adsorptive affinity of chlorophenoxy acids for glass surfaces. Extracted residues of 2,4-D and 2,4,5-T were adsorbed onto a column of fine mesh glass beads, and subsequently esterified with diazomethane for GLC quantitation, using an electron capture detector. Prior to injection, the esterified sample is cleaned up by passing through a Florisil column.
