摘要：

A differential pulse polarographic method has been developed for determination of acrolein from 0.05 to at least 0.50 mg/l in natural water samples. Acrolein is measured at about -1.2 V vs. SCE (NaCl) at pH 7.2 in phosphate buffer solution (0.09 M) with ethylenediaminetetraacetic acid added (0.09%) to prevent interference from zinc. The pH in the 6.8-7.6 range and zinc at 2.0 mg/l do not affect the recovery of acrolein. Seven replicate analyses of standard solutions containing 0.10 and 0.30 mg/l of acrolein give relative standard deviations of 7.6 and 4.3% and percentage accuracies of -2.9 and -3.3.
