摘要
采用重量分析法和络合滴定法测定了电厂湿法脱硫废弃物中主要成分硫酸根、亚硫酸根总含量及钙、镁离子总含量。并以乌拉山发电厂脱硫废弃物为例进行分析,所测结果允许差在规定范围之内,标准偏差较小,符合实验和工业要求。
In the paper,an improved gravimetry was provided to assay total content of sulfate and sulfite in desulphurized waste.Besides,total content of calcium and magnesium was determined by EDTA complexometric titration.The method provided was used to analyze desulphurized waste of Wula mountain power plant.The measured result of allowed tolerance is within the prescribed limit and standard deviation smaller,which is consistent with experimental and industrial requirements.
