| Abstract: | Ion exclusion chromatographic was adopted for determination of C 2 C 5 carboxylic acids in this study. 4% 1 butanol in water with very lower condictivity was selected as eluent. C 2 C 5 acids were seperated well and their sensibility are higher. So the method was used to determine C 2 C 5 carboxylic acid in environmental samples. |
