摘要
硫酸亚锡的制备方法可分为化学法和电化学法．在化学制备法中，用ＮＨ４ＨＣＯ３作沉淀剂的氧化亚锡－硫酸合成法目前仍为制备硫酸亚锡的主要化学方法之一，其锡的转化率为８５．６％，产品纯度可达９８％．电化学方法可制备纯度高达９９％以上的产品．阴离子隔膜电解法电流效率达到了９９％，节能明显，基本无污染，是一种最有前景的制备方法．
The preparation of stannous sulfate can be classified as chemical method and electrochemical method currently , stannous oxide-sulfuric acid synthesis with NH4HCO3 as pre-cipitant is still one of the main chemical methods, with the conversion of tin being 85. 6% and the purity of product up to 98%. Products with a purity over 99% can be prepared with electrochemical methods. Anion-diaphragm electrolysis, featuring a current efficiency up to 99%, obvious energy saving and almost non-pollution, is one of the most promising prepara-tion methods.
