摘要
研究了镁及镁合金中钇含量的测定方法。该方法分析相对标准偏差：0.47%~1.09%,加标回收率：96%~98.8%。该方法简便快捷、定值准确。
The measuring methods for Y in Mg and Mg alloy were described in the paper.A measuring method for Y in Mg and Mg alloy by arsenazo Ⅲ photometric method was put forward.The relative standard deviation of the method is 0.47%～1.09%,and the standardized recovery is 96%～98.8%.This method is simple,convenient,rapid and accurate.
