| 内容記述 | In order to clarify the adsorption equilibrium for the species of the extractant and the extraction complex, the interfacial tensions between the aqueous and the organic solutions were investigated, using equilibrated kerosene solution in the presence of 5-dodecylsalicylaldoxime （LIX® 860-IC） and aqueous solution in the presence and absence of nickel ion. The interfacial tensions decreased with increasing in the concentration of LIX® 860-IC. Experimental results of the interfacial tension were analyzed by Gibb’s adsorption isotherm. The adsorption equilibrium constant and the interfacial area for the extractant and the extraction complex were determined. The extraction rate of nickel from the aqueous ammonium sulfate solution with LIX® 860-IC in kerosene was investigated using a Lewis-type transfer cell. The concentration effects of extractant, nickel, and hydrogen ion on the extraction rate were examined. The extraction rate increased with increasing in the oncentrations of nickel and the extractant, and approached to constant values depending on the extractant concentration at a high concentration of nickel. The rate increased with decreasing in the concentration of hydrogen ion, and approached to constant values depending on the extractant concentration. These results were analysed based on an interfacial reaction model in which the reaction proceeds between an extractant species adsorbed at the interface and nickel ion in the aqueous solution. The extraction rate is interpreted based on the rate equation in which the interfacial reaction between a 1:1 nickel chelate complex species adsorbed at the interface and the extractant in the organic solution is the rate-determining step. The reaction rate constants and equilibrium constants were determined. |
