RESEARCH FABRICATION AND APPLICATION OF MnO2 FOR WATER TREATMENT
In this work, MnO2 were prepared successfully by chemical and electrochemical methods. The adsorption of the MnO2 oxides were investigated by using the changes in COD index and PZCpH. The Structural mophology and size of the MnO2 oxide particles were study by SEM. It was revealed that the adsorption is reached to the quasi saturated state after only 1 hour, of about 95% the pH value at point of zero charge( PZCpH value) of the obtained MnO2 for the invesetigated solution, is considered as equal of about 5.4 ÷ 5.5.
