Thorium removal from weakly acidic solutions using titan yellow-impregnated XAD-7 resin beads: kinetics, equilibrium and thermodynamic studies

To remove Th(IV) ion from acidic solutions (pH 2.5–2.7), an extractant-impregnated resin (EIR) was fabricated by impregnation of Ambelite XAD-7 resin beads with titan yellow as extractant. Various physicochemical factors such as pH, contact time, temperature, sorbent dose and initial concentration o...

Description
Summary:To remove Th(IV) ion from acidic solutions (pH 2.5–2.7), an extractant-impregnated resin (EIR) was fabricated by impregnation of Ambelite XAD-7 resin beads with titan yellow as extractant. Various physicochemical factors such as pH, contact time, temperature, sorbent dose and initial concentration of thorium were investigated. The isotherm data was well interpreted by the Langmuir model. Kinetic experiments data showed that the sorption process could be described by Weber–Morris kinetic model. Thermodynamic studies revealed the feasibility, spontaneity and endothermic nature of sorption process. Desorption experiments showed that the EIR could be reused without significant losses of its initial capacity.
