Abstract:The simultaneous analysis conditions of main elements (Si, Al, Ba and Ca) in silicon-aluminum-barium-calcium series alloy by inductively coupled plasma atomic emission spectrometry (ICP-AES) were discussed. The determination method was established. The silicon-aluminum-barium-calcium alloy sample was melted at high temperature with boric acid-anhydrous sodium carbonate mixed flux, and then leached and acidified with hydrochloric acid. The pretreatment time of sample was reduced from original 5-6 h to 45 min. By experiments, the optimal analytical lines were obtained as follows: Si 251.611 nm, Al 396.152 nm, Ba 233.527 nm and Ca 317.933 nm. Under the selected optimal instrumental parameters and experimental conditions, a group of standard sample was determined. The found results of four elements were consistent with the certified values. The relative standard deviations of Si, Al, Ba and Ca were in range of 0.12 %-0.63 %. The relative error was less than 3 %.
