Abstract

A method for the determination of Al, Fe, Ca, Cr, Mn, Ni, Si and Ti elements in ferrum aluminum silicon alloy by inductively coupled plasma atomic emission spectrometry (ICP-AES) was described. The influence of ICP-AES operating conditions, sample dissolution methods and spectral lines were studied. The preferable experimental conditions were examined, and the influences of coexistent elements on the signals were investigated. The method was applied to the determination of elements in ferrum aluminum silicon alloy samples, and the measured results were in good agreement with the recommended values of the standard steel. The detection limits of the method were 0.029 microg x mL(-1) for Al, 0.004 microg x mL(-1) for Fe, 0.0075 microg x mL(-1) for Ca, 0.0015 microg x mL(-1) for Cr, 0.0009 microg x mL(-1) for Mn, 0.0027 microg x mL(-1) for Ni, 0.045 microg x mL(-1) for Si and 0.003 microg x mL(-1) for Ti. The relative standard deviation (n=6) of this method was between 0.3%-1.8%, and the recoveries by standard addition were in the range of 96.7%-102.9%. The method was used to determine the amount of silicon in alloy samples with satisfactory results, which agreed with those by the standard gravimetry. The method is characterized by good precision, easy operation and convenience to apply.
