Composite Material of Clay-biochar for Cadmium Ion Removal from Water
A research study of the synthesis of nanocomposite of clay-biochar material acquired from normal clay and biomaterial of Prosopis Juliflora for cadmium ion removal from aqueous solutions is reported. Composite materials were prepared by heating of ordinary clay and biomaterial of Prosopis at 500°C temperature and the synthesis was established with XRF, EDX, FTIR, XRD and SEM characterization. The results of characterized material showed that clay minerals successfully permeated the surface of biochar materials to form composites. The effectiveness of the composites in removing cadmium metal was determined by a batch adsorption procedure. The composite material produced a removal efficiency of 99% of cadmium ions. Adsorption was investigated using the adsorption isotherms of Freundlich and Langmuir which showed correlation r2 values of 0.924 and 0.932 respectively for the removal of cadmium ions from water. The results also revealed a pseudo second-order reaction for cadmium ions removal.
