摘要：
Ion exchange chromatography was applied to simultaneous quantitative analysis of fluoride, chloride, bromide, nitrate, sulfate and phosphate anions in commercial waste-oil biodiesel. The extraction of the anions was carried out with deionized water using separation funnel. The observed limits of detection in mu g.mL(-1) were, respectively: fluoride 0.0012; chloride 0.0029; bromide 0.0116; nitrate 0.0089; sulfate 0.0094 and phosphate 0.0267. The observed amounts in mg.Kg(-1)were, respectively: fluoride 1.714; chloride 8; phosphate 0.594; sulfate 1.773. The amounts of bromide and nitrate anions were lower than the limits of detection in all the studied samples and not detected. The method can be considered to be green because it uses small volumes of water, is simple, with fine recovery rates. Anions in biodiesel can be analyzed simultaneously by ion chromatography.
