Abstract:
Alginate encapsulated nano-hydroxyapatite beads were synthesized and characterized by Fourier transform infrared spectroscopy, Brunauer Emmett Teller surface analysis, and X-ray diffraction. Their adsorptive potential for Ni2C and rhodamine B was explored in batch mode and by fixed-bed column passage. In the batch system, maximum uptake capacity for Ni2C was 360 mg g¡1 and 480 mg g¡1 for rhodamine B. In the presence of humic acid, sorption was enhanced. For the continuous-flow system, adsorption was effective at low flow rate. For both pollutants, mass transport resistance increased during adsorption. The overall rates of rhodamine B and Ni2C uptake were found to be controlled by external mass transfer.
