摘要
在试验温度为5~50℃的条件下测定了硫酸钠在3种不同氯化钠浓度溶液中的溶解度,确定了氯化钙和氧化钙＋盐酸为原料的钙法脱除硫酸根的适宜原料加入量,探讨了用某工厂含钙废渣代替氯化钙来脱除硫酸根的方法。
The solubility of sodium sulfate in three kinds of different oncentration of sodium chloride solution is tested in the range of 5~50 ℃.The suitable raw material addition for removing sulfate radical by calcium method which takes calcium chloride,calcium oxide and hydrochloric acid as raw material is determined.And the method of removing sulfate radical by waste residues containing calcium from certain factory is discussed instead of calcium chloride.Foundatim item：supported by national natural science fund program of China（20676101）
