摘要 目的:建立HPD系列大孔吸附树脂的预处理方法.方法:采用气相色谱法(GC)和紫外分光光度法比较了2%NaOH对HPD系列大孔吸附树脂预处理的影响.结果:树脂先用2%NaOH浸泡后再用乙醇洗脱,对有机残留物的洗脱效果较好.结论:HPD系列树脂预处理方法为:树脂经2%NaOH浸泡洗脱后,在60℃,用乙醇浸泡、洗脱,洗脱流速为2 BV·h-1,乙醇用量为3~4倍柱体积,洗脱液的紫外吸收值为0.2~0.5.预处理的树脂经GC检测,苯未检出,其他有机残留物均低于10 mg·L-1,达到药用要求. Objective: To develop a method for the pretreatment of the series of HPD macroporous adsorption resin(MAR). Method: The effect of 2% NaOH to pretreatment of the series of HPD MAR was studied by gas chromatography and UV spectrometery. Result: The eluting effect by ethanol was better after the MAR was marinated and eluted by 2% NaOH. Condutlon: The 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·h^-1 at 60℃ 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·L^-1 in elutedMAR by GC. And the MARs match to the standard of medicine.
