SINTESIS DAN UJI AKTIVITAS KOMPOSIT MnO2/ABU LAYANG DALAM MENDEGRADASI ZAT WARNA MENGGUNAKAN METODE FENTON

Abstract

Dye waste has a negative impact on health and the environment, so it must be treated before being discharged into the environment. The Fenton method is an effective method for the degradation of dyes into environmentally friendly compounds. In this study, the synthesis of the MnO2/fly ash composite was carried out using the precipitation method. MnO2 was synthesized by mixing together KMnO4 and glucose in a ratio (3:1) which was then composited with 15% fly ash. The results of the XRD characterization showed that the type of MnO2 in the MnO2/fly ash composite was cryptomelane.The MnO2/fly ash composite was then applied for the degradation of methylene blue dye. Methylene blue degradation at a volume concentration of 1 mL H2O2, 10 mg composite and 50 ppm methylene blue, was able to degrade methylene blue 63,58 % in 120 minutes.
