    SINTESIS KOMPOSIT MnOx/ABU CANGKANG KELAPA SAWIT MELALUI METODE SOL GEL UNTUK DEGRADASI METILEN BIRU : VARIASI MASSA ABU CANGKANG
    (Elfitra, 2023-12) Irfan; Awaluddin, Amir
    The manganese oxide mineral is an oxidizer which plays an important role in the transformation of various compounds into simpler compounds. This mineral is generally mixed with manganese oxide which has a different structure and other metal oxides. Synthesis of manganese oxide can be carried out using the sol gel method. The ratio of reactants and concentrations as well as the presence of other compounds during the reaction greatly influence the structure of the manga oxide produced. The aim of this research is to examine the effect of shell ash mass on the characteristics of the MnOx/ACKS composite by mixing KMnO4 and glucose to form a gel, followed by the addition of ACKS. The structure of MnOx in the composite was determined by XRD. The results of XRD show the presence of cryptomelane, hausmanite, manganosite, birnessite phases. The relegation result is 74,13%.
