Notes : Adsorption Isotherms of Phenol and o-Cresol by Static Method

Yong Seok Choi

Abstract

Adsorption isotherm is the most fundamental information related to chromatography process. To find adsorption isotherms of phenol and o-cresol, static method was adopted in RP-HPLC. The concentrations of mobile and stationary phases were measured with different initial concentrations of phenol and o-cresol, 1, 5, 10, 20, 50, 100, 150, 200 mg/ml, respectively. The adsorption isotherms tested were Freundlich, Langmuir, Sips, and Ranke-Prausnitz equations. The experimental data were fitted by a regression analysis. Except the Freundlich equation, very good agreements were observed between experimental data and the calculated values.

단신 : 정적 방법에 의한 Phenol 과 o-Cresol 의 흡착 평형식

초록

흡착 평형식은 크로마토그래피공정에 관계되는 가장 기본자료이다. Phenol과 o-cresol의 흡착 평형식을 구하기 위해서 RP-HPLC(reversed-phase high performance liquid chromatography) 환경에서 정적 방법을 이용하였다. Phenol과 o-cresol을 초기에 각각 1, 5, 10, 20, 50, 100, 150, 200mg/ml 의 다른 농도를 실험하여 평형에 도달한 후 이동상과 고정상에서의 시료의 농도를 측정하였다. 측정된 데이터를 Freundlich, Langmuir, Sips 그리고 Ranke-Prausnitz식에 적용시켜 보았다. 실험된 데이터는 회귀분석을 통해 fitting 시켰다. Freundlich 식을 제외한 나머지 식은 실험값과 매우 흡사한 결과를 나타내었다.
