Title: Determination of Organic Acids in Fermentation Broth of Anerobic Fermentation using Combined Sludge and Food Waste by Ion Chromatography
Abstract: Ion chromatography was applied to the simultaneous determination of seven organic acids in fermentation broth of anerobic fermentation using combined sludge and food waste,including lactic acid,acetic acid,propanoic acid,n-butanoic acid,iso-butanoic acid,n-pentanoic acid and iso-pentanoic acid.An optimal elution program was established through experiment.Linear relationships of the seven kinds of organic aicds were good in the range of 2.00 mg/L-60.0 mg/L.The experiment showed that the detection limits were in the range of 0.250 mg/L- 0.580 mg/L,and the relative standard derivations of the eight determination results were3.7%-7.1%,and the recoveries of standard organic acids and fermentation broth samples were in the ranges of93.0%-108%and 90.6%-109%,respectively.
