چکیده
|
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%.
