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 50 mmol/L to 175 mmol/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% and 9 9 .5%,indicating this method can meet the requirements of analysis in desulfurization system.
