Abstract
암모니아와 팽창흑연에 함침된 금속염화물계의 흡착평형을 실험적으로 연구하였다. 이 평형을 두 종류의 균질표면으로 구성된 비균질표면으로 모델링하였다 각 균질표면을 Fowler-Guggenheim 등온흡착식으로 표현하고 평형과 흡착엔탈피 계산을 위한 방법을 제안하였다. 암모니아-염화망간과 암모니아-염화니켈계의 계산된 평형과 흡착엔탈피를 실험값과 비교하여 모델이 근사적으로 현상을 설명하는 것을 확인하였다.
Adsorption equilibria for ammonia-expanded graphite impregnated with manganese chloride and nickel chloride systems were experimentally studied. The equilibria were modelled by a two-patch heterogeneous system in which each homogeneous patch was described by the Fowler-Guggenheim adsorption isotherm. A method was also developed for calculation of adsorption enthalpy from the isotherm information. The model was found to approximately describe the adsorption isotherm and enthalpy.
