| 中文摘要 | in the present paper, the adsorption of thulium(ill) from chloride medium on an extraction resin containing bis(2,4,4-trimethylpentyl) monothiophosphinic acid (cl302, hl) has been studied. the results show that 1.5 h is enough for the adsorption equilibrium. the distribution coefficients are determined as a function of the acidity of the aqueous phase and the data are analyzed both graphically and numerically. the plots of log d versus ph give a straight line with a slope of about 3, indicating that 3 protons are released in the adsorption reaction of thulium(iii). the content of cyanex302 in the resin is determined to be 48.21%. the total amount of tm3+ adsorbed up to resin saturation is determined to be 82.46 mg tm3+/g resin. therefore, the sorption reactions of tm3+ from chloride medium with cl302 can be described as: tm3+ + 3hl((r)) <----> tml3(r) + 3h(+) the freundlich's isothermal adsorption equation is also determined as: log q = 0.73 log c + 3.05 the amounts (q) of tm3+ adsorbed with the resin have been studied at different temperatures (15-40degreesc) at fixed concentrations of tm3+, amounts of extraction resin, ion strength and acidities in the aqueous phase. |
