摘要
过氧化氢与二氧化钛两种试剂联合使用,取代原方法中剧毒试剂氰化钾来掩蔽干扰元素,络合滴定法测定耐硫变换催化剂中氧化镁的含量,并与原方法进行对比,测定结果与原方法相符合,回收率在97.60%～100.4%之间,相对平均偏差最大0.70%。
The hydrogen peroxide and titanium oxide were used to eliminate elemential interferences, by substituting for hypertoxicity reagent potassium cyanide used in original method of chelatometry for the determination of magnesium oxide content in sulfur tolerant shift catalyst. The recovery yield is 97.60% - 100.4%, relative deviation is less than 0.7%.
