Abstract
Adsorption of Ce(III) from aqueous solution by amino phosphate
modified nano TiO2 was investigated. Effects of pH of solution,
adsorbent dose, contact time, initial metal concentration and
temperature were examined. Experimental data were fitted well by
the pseudo second order model. Adsorption was well described by
Freundlich isotherm model with a maximum adsorption capacity of
25 mg/g. According to the obtained thermodynamic parameters, the
adsorption was a spontaneous and endothermic process. Effect of
interfering cations was studied. Distribution coefficient value for
Ce(III) was higher than La(III). Regeneration of adsorbent was
performed using HNO3 with efficiency greater than 84%.
