It was found that the efficiency of batch extraction method for the studied elements is almost similar for trioctyl phosphine oxide and trioctyl amine, both at low and higher acidity. This method was applied to the analysis of the elements in wastewaters. In addition, the back-extractions for iron, antimony and cadmium were studied. The interfering effects of sodium, potassium, magnesium, calcium, lead and cobalt were investigated. Blank values were low and recoveries were 100%, 100% and 88.3% for iron, antimony and cadmium, respectively, at 95% confidence level. The relative standard deviations for the determinations were found to be 1.0-6.0%. Detection limits (3 sigma) were 0.5 mu g L-1 for iron, 0.6 mu g L-1 for antimony and 2.9 mu g L-1 for cadmium.eninfo:eu-repo/semantics/closedAccessExtractionTrioctyl Phosphine OxideTrioctyl AmineIsoamyl AcetateBatch MethodAtomic Absorption SpectrometryLiquid-Liquid-ExtractionAtomic-Absorption SpectrometryPreconcentrationKetoneCdArticle162118121Q4WOS:0002449373000022-s2.0-33947144650N/A
