Abstract:
A method for determining the concentration of a phenoxy herbicide in an aqueous sample, by simultaneously phase-transfer catalyst extracting and alkylating an aqueous sample comprising a phenoxy herbicide to form a sample composition, and measuring an amount of the alkylated phenoxy herbicide in the sample composition. The method includes controlling factors such as pH of the aqueous matrix, temperature, extraction duration, type and amount of derivation reagents, and type and amount of phase transfer catalyst.
