description | The adsorption behavior of aromatic acids on Amberlite XAD-4 resin was investigated by measuring the distribution coefficient by batch method. The adsorption of solutes on XAD-4 was affected by the several factors such as, analyte concentration, the pH of solution and concentration of pairing ion. The enhanced adsorption of solutes on XAD-4 in the presence of tetraalkylammonium salt as an ion pairing reagent, referred to as ion interaction, was suggested to follow a double layer model where the pairing ion occupies a primary layer at the adsorbent while the solute anion and other anions in the system comlpete for the secondary layer. Therefore, the ability of an ion pairing reagent to enhance solute adsorption depended significantly on the type and concentration of counter-ion and co-anion accompanying the ion pairing reagent or salt used for ionic strength control. In addition, a good linear relationship between the logarithm of capacity factors measured by batch and elution method as a function of the concentration of ion pairing reagent and methanol can be used to predict the retention in elution method on the basis of capacity factors measured by batch method. 이온쌍크로마토그래피에서 방향족 유기산들의 머무름을 연구하기 위하여 Amberlite XAD-4 수지에 대한 분배계수 값을 측정하였다. 유기산들의 XAD-4 수지에 대한 흡착은 시료의 농도, 용액의 pH 그리고 이온쌍 형성시약의 농도에 따라 영향을 받는다. Tetraalkylammonium염과 같은 이온쌍 형성 시약에 의한 유기산의 XAD-4 수지에 대한 흡착 증가는 전기적 이중층에 의한 이온 상호작용에 기인됨을 알았으며, 유기산과 이온쌍 형성 시약과의 상호작용은 공존이온과 상대이온의 종류와 농도에 따라 영향을 받음을 알았다. 한편, 이온쌍 형성시약과 메탄올의 농도 변화에 따른 XAD-4수지에 대한 유기산의 뱃치법과 용리법에서 얻은 용량인자의 관계는 좋은 직선관계를 보여주었다. 따라서 뱃치법의 실험으로써 용리법의 머무름을 예측할 수 있는 가능성을 제시하였다. |
