摘要
研究了以稀盐酸溶液溶解样品，EDTA标准溶液配位，硫酸镁标准溶液返滴定，测定食品级磷酸镁中氧化镁的分析方法。该方法的回收率为97％-103％，RSD〈0．21％。
Determination of magnesium oxide from food grade magnesium phosphate was studied by dissolution of samples with dilute hydrochloric acid, coordination with EDTA standard solution and back titration with magnesium sulfate standard solution. The recovery and relative standard deviation were 97 - 103% and less than 0.21% respectively.
