Abstract

Rohm & Haas사에 의해 제조된 합성수지 흡착제, Amberlite XAD-4, XAD-7 및 XAD-1180을 사용하여 수용액상의 파라클로로페놀(p-chlorophenol) 및 2,4-디클로로페놀(2,4-dichlorophenol)의 흡착평형에 대한 특성들이 연구되었다. 흡착평형에 대한 실험결과들은 8가지 흡착등온식에 대한 비선형 회귀분석을 통해 이론적으로 고찰되었다. 실험 자료에 대한 회귀분석 결과, 각 합성수지 흡착제에 대한 파라클로로페놀 및 2,4-디클로로페놀의 흡착거동은 BET 등온식, Four-parameter 등온식, Freundlich 등온식, Redlich-Petersen 등온식 및 Sips 등온식을 통해 4.31%의 오차범위 내에서 성공적으로 재현되었으나 Langmuir 등온식 및 Toth 등온식에 의해서는 최대 8.49%의 오차로서 다른 등온식들에 비하여 비교적 높은 오차분포를 갖는 결과를 보였다.
