摘　　要：文章采用离子色谱法,结合在线渗析技术对水产品中多聚磷酸盐的质量分数进行了测定。该方法测定多聚磷酸盐离子在质量浓度0～10.0 mg.L-1线性关系良好,相关系数达到0.999。检出限为3.0～10μg.L-1,回收率为95.8%～104%,连续进样检测值相对标准偏差小于10%。试验结果显示该法分离度好,灵敏度高,检测结果准确,操作方便快速,适合水产品中多聚磷酸盐的测定。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.
