    PEMANFAATAN LEMPUNG ALAM MAREDAN SEBAGAI KATALIS HETEROGEN UNTUK PENGHILANGAN METILEN BIRU MELALUI PROSES FENTON
    (2-04-07) Hendru, Hendru; Awaluddin, Amir
    Methylene blue, commonly used dye in textile industry, is harmful to living organism and environment due to its resistance for degradation. The most effective method for dyestuff removal is heterogeneous catalyst based on Fenton reaction to produce OH radical. In this study, Maredan Clay (LM) can be used as a heterogeneous catalyst. The results of catalyst preparation were characterized by X-ray Diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Characterization results showed that catalyst contained quartz, kaolinite, muscovite and hematite minerals with morphology like irregular spheres. LM give optimum result in methylene blue removal under conditions of pH = 3, H2O2 = 6.7 mM, Fe-LM = 0.75 g/L, initial concentration = 50 ppm, at room temperature
