| Abstract: | The coordination adsorption resins were prepared by loading different transition metal ions on macroporous sulphonic resin(D72) and acrylic acid resin(D152) respectively, and the coordination adsorption of VB 12 on the resins in various media has been investigated. The sulphonic resin loaded with Zn 2+ (D72Zn 2+ ) was found to possess the best adsorption and desorption properties. The adsorption isotherm of VB 12 on D72Zn 2+ resin in ethanol fits the Langmuir adsorption equation, and the saturated adsorption capacity from ethanol reaches 61 mg/g. The leakage capacity by column operation was 34 mg/g and water appeared an effective eluant with 94% desorption percentage. |
