Study on the Method of ICP-AES Determinating Ca、Ba、Al in FeCaBaAl Alloy

Fang Yan-xia

Abstract

The method of measuring the Ca、Ba、Al in Fe Ca Ba Al by ICP-AES and the best measuring conditions were studied.The influence of acid for dissolution and coexisting ions in sample were studied,recovery rate,accuracy and precision of the experiment were measured.The result show that measure Ca、Ba、Al in FeCaBaAl by this method the RSD(%) was Al0.50,Ca0.15,Ba0.24,the recovery rate was between 97.0%～104.0%.
