ABSTRACT
Objective:
To establish a method for the determination of organic residues ( hexane, benzene, toluene, xylene and sty-rene) in macroporous adsorption resins.Methods:
Headspace-GC with a DB-624 column was used to determine the residues in macro-porous resins. The inlet temperature was 200℃ and the FID detector temperature was 240℃. The column temperature programming was as followsthe initial temperature was 40℃, maintained for 3 min, and then raised to 200℃ with the rate of 14℃/min and kept for 2 min. The solvent was methyl alcohol and the carrier gas was nitrogen. HPLC was applied to determine the contents of the five resi-dues.Results:
The contents of the five organic residues were all below 20‰ in five macroporous resins in common use including D101, HPD100, AB-8, DM301 and NKA-9.Conclusion:
The method is simple,accurate and reproducible. It can be used in the res-idue determination of macroporous resins.
