Removal of metal ions from water using oxygen plasma

Abstract Zinc ion dissolved in water is attempted to be removed by generating the oxides of zinc using oxygen gas dielectric barrier discharge (DBD) plasma system. The removal rate oxides’ production (ZnO and Zn(OH) 2 ) are measured at different treatment periods penetration water. deposit increases initially then decreases with period. maximum (29%) from achieved period 10 min, where pH lower (7.4). From FTIR generation properties oxide can recognized. Initially amount ozone due both ZnO . After that, 4 2- even when total decreases. Therefore, remove forming metal deposit, active oxygens must controlled keep than around 7.5. Because increasing treated depends on concentration
