Research on Different Detection Methods for SO3 Content in Phosphogypsum
To explore a detection method with high accuracy and fast detection speed for detecting SO3 content in phosphogypsum.This study focuses on the analysis of SO3 content in filter gypsum using weight method,inductively coupled plasma emission spectroscopy,crystal water exchange algorithm,X-ray fluorescence analysis,and fully automated analysis system method.The precision,accuracy,spiked recovery,and analysis time of each method are used as the evaluation indicators.The key findings are as follows:① The weight method,as the SO3 benchmark method,has the best precision,followed by the fully automated analysis method,and the ICP detection method is the worst;②The accuracy of the fully automated analysis method is the best,the weight method is slightly lower,and the ICP method is the worst;③The weight method showed the best results in the spiked recovery experiment,while the ICP method had the worst results;④The fully automated analysis method has the fastest detection speed and the highest degree of automation.In summary,The fully automatic analysis method is used to analyze the SO3 content in phosphogypsum,which has accurate and reliable analysis data,the shortest analysis time,and the highest degree of automation.This method provides a new idea for detecting the SO3 content in phosphogypsum,and can also better meet the needs of rapid detection of sulfur trioxide content in phosphogypsum samples.
