| Abstract: | The properties and mechanism of adsorption gallium from sulfuric acid solution by D2EHPA levextrel resin were studied. The resin showed a maximum distribution coefficient for Ga(III) adsorption at pH=2.8. The steady adsorption capacity was 42.4mg/g and the adsorption enthalpy was 43.2kJ/mol. The isothermal adsorption equation was Q=58.9C0.12 (298K). The adsorption mechanism has been investigated by IR measurement. |
