摘要: 通过离子交换色谱法,建立不同厂家阿胶及动物皮胶中Cl-、SO42-、NO3-、PO43- 4种阴离子的测定方法。结果表明,4种阴离子分离效果良好,Cl-、SO42-、NO3-、PO43-分别在0.000 922~0.023 1、0.001 09~0.027 3、0.000 167~0.004 18、0.000 314~0.007 86 mg/mL浓度范围内线性关系良好,平均加样回收率在98.7%~101.0%。该测定方法结果准确、灵敏、可靠,重现性较好,可用于阿胶及动物皮胶中4种阴离子含量的测定。

Abstract: To establish a method to determine the contents of Cl-,SO42-,NO3-,PO43- in animal skin gelatin and E jiao from different manufacturers by IEC. Results showed that Cl-,SO42-,NO3-,PO43- were well separated and showed good linearity at 0.000 922~0.023 1, 0.001 09~0.027 3, 0.000 167~0.004 18, and 0.000 314~0.007 86 mg/mL. The average recoveries were between 98.7%~101.1%. Result of this method was accurate, sensitive, credible and repeatable. It could be applied to the content determination of 4 kinds of inorganic anions in animal skin gelatin and E jiao from different manufacturers.
