Abstract
Abstract A quantitative, rapid, sensitive, and isomer-specific method for the analysis of chlorophenols in natural water by in situ chloroacetylation is presented. Without pre-extraction, phenols in water are chloroacetylated by chloroacetic anhydride in the presence of K2CO3. Because of differences in reaction kinetics and stability, various chloroacetates were removed from the reaction mixture at different intervals. If analysis of other classes of neutral organic compounds is also required, a more elaborate procedure involving solvent extraction of organic compounds and back-extraction of phenols into K2CO3 solution followed by chloroacetylation is proposed. When a 12 m OV-1 fused silica capillary column was used, 22 phenol chloroacetates were easily resolved in a single run. Using distilled and natural water samples, this method has been validated and shown to be applicable over a concentration range of 0.1 to 100 μg/L of the phenols studied.
