    PENGARUH KONSENTRASI HIDROGEN PEROKSIDA PADA DEGRADASI METHYLENE BLUE MENGGUNAKAN MANGAN OKSIDA YANG DISINTESIS DENGAN METODE SOL-GEL

    The manganosite type manganese oxide has been used for degradation of methylene blue using hydrogen peroxide (H2O2) on an oxidant. The manganese oxide has been synthetis using sol-gel method with KMnO4 and glucose as an reducted. The XRD result was the type manganosite (MnO) with the high level of crystalline. From SEM result manganosite structures with the morphology like cotton dots. The effect of hydrogen peroxide concentration on the degradation of methylene blue was by keeping other experimental parameter are concentration of hydrogen peroxide with reaction time 120 minutes, detected small degradation of methylene blue without the presentation of hiydrogen peroxide. The addtion of methylene blue increase degradation significant when added 10 ml hydrogen peroxide. However, no significant degradation when concentration of hydrogen peroxide was increased to 15 ml
