Speciffic Adsorption of Metal Complexes of Tetraphenylporphyrin at Dodecane-Water Interface
Interfacial adsorption of the metal complexes of tetraphenylporphyrin (TTP) was found out in the dodecane-water system by a high-speed stirring method. Among metalloporphyrins of five metals examined, ZnTPP and VOTPP showed appreciable adsorptivity at dodecane-water interface and adsorption constants were determined by applying Langmuir isotherm. The interfacial adsorptivity of complexes decreased in the order, ZnTPP > VOTPP > CoTPP, NiTPP, CuTPP.
