Abstract��
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.
