摘　　要：研究了碱处理笼形聚偕胺肟树脂（ＢＣＡＯ）对饱和一元脂肪酸、二元脂肪酸、不饱和脂肪酸、α一取代乙酸和羟基羧酸的吸附作用。发现ＢＣＡＯ对羧酸强烈吸附．一元羧酸在ＢＣＡＯ上以多分子层吸附占优势，二元和三元羧酸则以单分子层吸附为主要特征；后者作为阴离子聚体吸着在ＢＣＡＯ表面，形成了对外来的羧酸阴离子起排斥作用的离子场．The adsorption of carboxylic acids by alkali-treated 'cage' polyamidoxime adsorbent (BCAO) was investigated. The multilayer adsorption predominates the adsorption of monocarboxylic acids on BCAO, but the monolayer adsorption is the characteristics of the dibasic and tribasic acids. Possibly, the polybasic acids adsorbed onto BCAO give a negatively ionic field which repels the entering carboxylic anions.
