| 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 adsorbent dose) for removing of cadmium ions from wastewater. The SEM of nano-particles after treatment of wastewater revealed that surface texture of the blank adsorbents changed totally due to the adsorption of cadmium ions on the particles. At the optimum operating conditions, the removal efficiency of cadmium ions reached 98.88 %. 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. | ||||
