Research Progress of Analysis Techniques for Strontium Solid Phase Extraction Disk Technique

The strontium solid phase extraction disk developed in recent years is a new method for analyzing radiostrentium. In comparison with traditional radiochemical analysis method, this method is faster and more effective, the disk allows the solution to pass through in high flow rate （50mL/min）. It makes the disk suitable to analyze the large volume water sample and money spent will be cut down greatly. In this paper, progresses on analysis techniques of 90St by strontium solid phase extraction disk technique were reviewed. Chemical recovery, radiometric interferences and application for water sample monitoring were evaluated along with variable sample-volume, flow-rate and acid concentration. The aim is to provid a periodic summary for this study, hope to play a certain role to the development of strontium solid phase extraction disk analysis technology in our country.
