dc.description.abstract |
Manganese oxide as cryptomelane type was synthesized by citric acid sol gel. The effect of doping method between Co-MnO2 has been studied. The purpose of this research is to determine the catalitic activity of Co-MnO2 in methylene blue degradation. The characterization of Co-MnO2 catalyst was evaluated using X-ray Diffraction (XRD), Scanning Electron Microscopy-Energy (SEM) and Atomic Absorption Spectrophotometer (SSA). The morphology of Co-MnO2 catalyst was irregular. Catalitic activity Co-MnO2 type cryptomelane which doping with Co metal ion using method A was 76.839 % at 120 minutes and using method B was 78.173% at 120 minutes. The conclusion of this research that method A more effective than method B. |
