大孔吸附树脂有机残留物测定方法

本研究以强极性、极性、弱极性和非极性4种吸附树脂为原料,采用气相色谱分别测定其在中性、酸性、碱性以及超声波提取条件下所含有机残留物的种类,共检测出了13种主要化合物杂质,同时发现经超声波处理后,有机残留物种类最多,其次是酸碱条件,在中性条件下有机残留物最少。该结果可以用于指导检测食品药品中所使用的大孔吸附树脂有机残留物的含量。

Determination of Organic Residues in Macroreticular Resin

Organic residues in macroporous adsorption resins were detected by gas chromatography. Four types of resins were selected to represent the strong polar resin,the polar resin,the weak polar resin and the nonpolar resin,respectively. The resins were extracted by alcohol under four different conditions,and then the extracted liquids were detected by gas chromatography. The influences of pH value and ultrasonic effect were investigated. The results showed that the contents of organic residues varied greatly in 4 kinds of conditions and totally 13 kinds of residues were found in this method. With ultrasonic extraction by alcohol,most organic residues were detected,which means it is an effective method to treat macro- porous adsorption resins before they are used in food and medicine product. This conclusion may be used to guide the determination of organic residues in macroreticular resin.
