| 摘 要： | 建立了一种简单、快速的用离子色谱法测定海产品中的三聚磷酸盐的方法。以碳酸钠和碳酸氢钠溶液为淋洗液,利用阴离子色谱系统等度洗脱,通过对色谱分析条件的优化,选择13 min内出峰的三聚磷酸盐进行定量分析。结果表明:迁移时间和峰面积的最大相对标准偏差(RSD)分别为1.42%和2.56%。标准曲线的线性相关系数R2=0.999 7,检出限为3.0μg.mL-1(S/N=3)。以建立的方法测定鱿鱼中的三聚磷酸盐,结果显示,三聚磷酸盐的平均回收率为98.4%。 |

| Abstract: | A simple, rapid method for determination of tripolyphosphate was developed. The quantitative determination of tripolyphosphate was accomplished by ion chromatography within 13 min with elution of sodium earbonate and sodium bicarbonate. The max relative standard deviation （RSD） was 1.42% for the migration time and 2.56% for the peak area. The eorrelation coefficients （R^2） was 0. 999 7. The detection limits calculated were 3.0 μg·mL^-1 （S/N=3）. The average recovery was 98.4%. The method was used to determine the concentration of tripolyphosphate in calamari. |
