| Abstract: | The polyphosphates in aquatic products was determined by ion chromatography with inline dialysis. Within the concentration range of 0 - 10. 0 mg.L-1, the linear correlation coefficient is 0. 999; the limit of determination is 3.0 - 10 μg.L-1 ; the recovery is 95.8% - 104% ; the RSD is less than 10%. The method, which is sensitive, accurate, simple, rapid and has a good efficiency of separation, is suitable for determining polyphosphates in aquatic products. |
