Abstract
Nanomagnetic-hydroxyapatite (NMHAp) has been synthesized and characterized by means of FTIR and TEM analysis. The sample was tested for the removal of Cd2+ ions from their aqueous solutions using batch method. The presence of magnetic particles facilitates the recovery of adsorbent after adsorption process. The specific surface area of the prepared sample is about 58 m2/g. The uptake value obtained was 80.72 mg/g. Results showed that the Langmuir isotherm better fits sorption data than Freundlich model. Factors influencing the removal percent as pH, contact time, adsorbent dose and initial metal ion concentration have been discussed.
