采用温度滴定法检测脱硫浆液中硫酸根含量
摘要
采用温度滴定法对火电厂脱硫浆液中的硫酸根进行了定量分析。与传统方法相比
温度滴定法测定硫酸根操作简单、快速、准确度高
适合大批量样品的连续分析。对硫酸根含量在50~175mmol/L样品的测试结果表明
测试结果的相对标准偏差在0.3%~1.1%之间
加标回收率在97.1%~99.5%之间
能够满足脱硫系统分析测试的要求。
Abstract
By thermometric titration method
sulfate ion in FGD equipment of a fossil fuel power plant was determined.Compared with the conventional method
this new method is easy to follow
and has fast speed and high accuracy
which is suitable for continuous analysis of large scale samples.Detection for samples with sulfate iron concentration ranging from 50mmol/L to 175mmol/L shows that
the relative standard difference(RSD)of the results is between 0.3% and 1.1%
and the recovery rate is between 97.1% and99.5%
indicating this method can meet the requirements of analysis in desulfurization system.
