Abstract：The aluminium alloy sample was dissolved with sodium hydroxide solution followed by acidification with dilute sulfuric acid. The solution was transferred into separating funnel. The boric acid in solution could react with certain amount of mandelic acid and malachite green to form ternary complex, which could be quantitatively extracted with benzene. The extract liquor was directly injected into the organic sampling system of inductively coupled plasma atomic emission spectrometer (ICP-AES). The content of boron in ammonium alloy was determined using B 249.678 nm as analytical line. The sample dissolution method, the extracting reagent, the extraction method and conditions (time and acidity) were selected. The physical interference was eliminated by matrix matching method. The mass fraction of boron below 1.00 mg/L was linear to the emission intensity. The linear correlation coefficient of calibration curve was r=0.999 3. The detection limit of boron was 0.001 mg/L. The standard sample and owned sample were determined according to the experimental method. The found results of standard sample were consistent with the certified values. The relative standard deviation (RSD, n=10) of determination results of owned sample was less than 5%. The recoveries were between 80% and 100%. The proposed method was applicable for the detection of boron in aluminium alloy with minimum mass fraction of 0.000 1%.
