ActiveMethods for chemical analysis of sodium stannate - Part 7: Determination of alkali insoluble matter - Gravimetric analysis
锡酸钠化学分析方法 第7部分：碱不溶物的测定 重量法
Application Summary AI generated
This standard specifies a gravimetric method for determining the alkali insoluble matter content in sodium stannate, a chemical used primarily in electroplating and tin plating processes. It is applied in quality control laboratories within the chemical manufacturing industry to ensure the purity of sodium stannate by measuring residues that do not dissolve in alkaline solutions. The method is critical for verifying product specifications in industrial applications such as metal surface treatment and catalyst production.
