摘    要:本文提出了两种测定菱镁粉中游离MgO的方法。着重讨论了用醋酚甲酯—醋酸作为选择性溶剂,在适当条件下浸取菱镁粉,使有效游离MgO溶解完全并与不溶残渣分离后,用EDTA滴定法测定Mg~(2+),直接计算有效游离MgO%的方法。

关 键 词:菱镁粉  游离氧化镁  化学物相分析

Abstract:In this paper, there are two methods for determination of free-MgO in magnesitepowder. In suitable condition methyl acetate-acetic acid is used as a selective solvent, the effectivefree-MgO of magnesite powder can be immerged. After magnesia was dissolved completely, the so-lution was separated from undissolved remains, the Mg~(2+) could be titrated by EDTA. The percentageof effective free-MgO can be calculated directly.
Keywords:magnesite powder  free magnesunm oxide  hemical phase analysis
