Wollastonite ceramic/CuO nano-composite for cadmium ions removal from waste water

Abstract

NANO-PARTICLES, within 29-45 nano-meters, based on wollastonite were prepared with/ without CuO through wet method. The adsorption process was occurred on nano-particles powder ceramic at different conditions (pH, contact time and dose) for removing of cadmium ions from waste water. The SEM of nano-particles after treatment of waste water revealed that, surface texture of the blank adsorbents changes totally due to the adsorption of cadmium ions on the particles. At optimum operating conditions (at pH 9) cadmium ions removal reached 98.88% after measurement by ICP and EDX techniques. The obtained results showed that the produced ceramic nano-particles could be used efficiently for removal of cadmium ions with reasonable simple and low cost technique.
