铅/氧化铝催化剂中是一种工业成品催化剂,广泛应用于工业生产中,具有良好的催化活性,而催化剂中铅的负载量,直接决定了催化剂的活性。本文研究了用EDTA容量法测定三氧化二铝基体催化剂中铅含量的方法,并对实验过程中的关键步骤做了详细剖析,对结果做了回收率试验,证明此方法数据准确可靠,操作简单易行。 Lead / alumina catalyst is an industrial finished catalyst, widely used in industrial production, has good catalytic activity, and the amount of lead in the catalyst directly determines the activity of the catalyst. In this paper, the method of measuring the lead content in the alumina matrix catalyst by EDTA volumetric method was studied. The key steps in the experiment were analyzed in detail. The recovery rate of the results was tested, which proved that the method was accurate and reliable, and the operation was simple Easy to do.
