Abstract:
OBJECTIVETo develop a method for the pretreatment of the series of HPD macroporous adsorption resin (MAR).
METHODThe effect of 2% NaOH to pretreatment of the series of HPD MAR was studied by gas chromatography and UV spectrometery.
RESULTThe eluting effect by ethanol was better after the MAR was marinated and eluted by 2% NaOH.
CONCLUSIONThe pretreatment of the series of HPD MAR was: after marinated and eluted by 2% NaOH, the series of HPD MAR were eluted by ethanol at 2 BV x h(-1) at 60 degrees C for 3-4 bed volumes (BV). At then the UV absorbance of eluate was 0.2-0.5. Benzene was not detected and the other residues less than 10 mg x L(-1) in eluted-MAR by GC. And the MARs match to the standard of medicine.
