摘要: An Ion-exchange/derivatization procedure is described for the determination of C_1-C_5 volatile fatty acids in a range difficult aqueous matrices. The resulting p-bromophenacyl esters may be separated via either HPLC or GLC techniques depending on desired selectivity and sensitivity. Micromolar concentrations these can determined to better than ±0.20 μM within 95% confidence intervals. Sewage marine sediment pore water analyses performed small samples (<25 ml). Similarly, nanomolar determinations are possible 1-4 L rainwater samples. analytical method rapid, economical, lends itself routine applications involving parallel other soluble compounds.
