dc.description.abstract |
Manganese oxide is one of the metal oxides that has been used as a catalyst to degrade
various organic wastes. Among manganese oxide catalysts, manganese oxide MnO
(manganosite) has not been widely studied and synthesized. In this study using
bentonite as a support which aims to increase the catalytic activity of the MnO
composite. This study aims to synthesize MnO-bentonite composites with various
compositions of 5% and 15% MnO directly and indirectly using the sol-gel method
which were then characterized using XRD and BET instruments to determine the crystal
size, surface area and pore size of the MnO composite. -bentonite. To see the catalytic
activity of the MnO-bentonite composite, we will test and see the degradation efficiency
of methylene blue using a UV-Vis spectrophotometer. The results obtained from this
research are that the type of MnO-bentonite composite that has good degradation
efficiency is the directly synthesized MnO-bentonite composite with a composition of
15% with a mass variation of the composite 0.05 g; methylene blue initial concentration
of 50 ppm and 15 mL peroxide volume with a degradation efficiency of 92.92%. |
