摘要
分析了库仑滴定法测定煤灰中三氧化硫的过程,同时针对该法对少数硫酸钙含量特别高的煤灰样测试结果不理想的情况进行了相应的实验探讨。实验结果表明,在煤灰中加入活性炭可明显提高测试的速度和准确性。
The determination of the sulphur trioxide in coal ash with coulometric titration method is analyzed in this paper. For a few ash samples with ultra-high calcium sulfate content, the results of determination are not good. And the corresponding tests show that the addition of activated carbon in coal ash can improve the speed and accuracy of tests obviously.
