摘要
提出了脱硫石膏中亚硫酸钙和碳酸钙含量的分析方法 ,其主要原理是将一份试样分为两部分 ,先取一份 ,用碘量法测量其中亚硫酸钙的含量 ;另一份试样用盐酸溶解后 ,用氢氧化钠反滴定的方法测量出碳酸钙和亚硫酸钙的总含量 ,然后由差减法得到碳酸钙的量。
A method of analyzing the content of calcium sulfite and of calcium carbonate in the product from wet flue gas desulfuration has been proposed. The main principle of the said method is to divide a sample into two parts, and the persentage composition of calcium sulfite in the first part of sample is measured by using the iodometric method, and then the other part of the sample is disolved in hydrochloric acid, and the total content of calcium sulfite and calcium carbonate being measured by using sodium hydroxide for reverse titration. Finally, the content of calcuim carbonate can be obtained from the difference of substraction method.
