Pengaruh Ion Perak Terhadap Transformasi Birnessite Menjadi Cryptomelane Dan Sifat Katalitik Terhadap Degradasi Metilen Biru

---

ABSTRACT
Birnessite and cryptomelane are typical layered and tunnel manganese oxides and both can be used as a heterogeneous catalysts for the degradation of organic wastes using heterogeneous Fenton reaction. The aim of this study was to synthesize birnessite and cryptomelane using 5 variations of reflux times (1, 3, 6, 9 and 12 hours) with precursors of KMnO4 and C6H12O6 using Ag+ (AgNO3) as dopant sources (1, 5 and 10% w/t). The doping approach is carried out by mixing all the reactants including doping ion (in one reaction system). The as-synthesid Ag-birnessite-cryptomelane and Ag-cryptomelane were characterized using X-ray diffraction (XRD) and Brunauer, Emmet And Teller (BET). The Ag-cryptomelane with Ag 1% within 12 hour reaction times displays highest surface area of 23.560 m2/g. The as-synthesized catalyst was then applied for the degradation of methylene blue (MB) using H2O2 as an oxidant. Ag-birnessite-cryptomelane 1 hour 1% is a catalyst with a maximum degradation of 75,44% for 120 minutes of degradation times.
Keywords : birnessite, cryptomelane, doping, catalyst, methylene blue
