▲ [11a-Z03-2] Effect of oxygen plasmas on the removal of zinc ion from water

Zinc ion dissolved in water is attempted to be removed by generating the zinc oxide (ZnO) using the ozone oxidation treatment system. The amount of ZnO production were measured at different treatment periods of the oxygen plasma irradiation on water. The amount of the deposit increases initially up to 3 min, and then decreases with the irradiation period. The maximum removal rate of zinc from water is achieved at the treatment period of 1 min.
