吸光光度法测定铸造铝合金中硅、镁含量

Determination of Si & Mg content in casting aluminium-alloy by absirptionphotometry

本文提出了一次溶样测硅、镁的方法。试样用碱溶解后 ,用硝酸酸化。取所制溶液采用吸光光度法分析硅、镁含量 ,该法准确、简便 。

This paper presents a method in which the content of silicon and magnesium all be measured with only one test specimen dissolution.Test specimen shall be dissolved with alkali,Then treated with nitric acid.The solution shall be used for analyzing silicon and magnesium.Both Si and Mg shall be measured by absorptiophotometry
