Beschreibung
Zusammenfassung:	The present invention relates to a method for regenerating waste silica resin for chromatography without removing the resin from the chromatography column. The method comprises three steps, i.e., contacting the chromatography resin with a regeneration solution, neutralizing the regenerated chromatography resin with a neutralizing solution, and washing the neutralized chromatography resin with a washing solution. 本发明涉及一种在不从色谱柱中拆卸树脂的情况下使用于色谱法的废二氧化硅树脂再生的方法。该方法包括3步，即：使色谱树脂与再生溶液接触，用中和溶液中和再生后的色谱树脂，以及用洗涤溶液洗涤中和后的色谱树脂。
