    PENGARUH DOPING MANGAN TERHADAP KEMAMPUAN KATALIS NANOPARTIKEL HEMATIT MENDEGRADASI METILEN BIRU
    (2021-03) Fitri, Ainun Syarifatul; Erwin, Erwin
    Textile industrial waste is one of the factors causing water pollution. Textile industrial waste contains organic material in the form of synthetic dyes. One way to overcome pollution by textile industrial waste is using a degradation method with the help of a catalyst. This study aims to determine the ability of hematite (α-Fe2O3) magnetic nanoperticle doped with manganese (Mn) to degrade methylene blue. Hematite (α- Fe2O3) magnetic nanoparticle were obtained from natural sand in Logas Village, Kuantan Singingi Regency. Natural sand was synthesized by ball milling method for 120 hours then doped with Mn as much as 0%, 10%, and 20% of the total mass and milled by ball milling for 20 hours. Testing the ability of Mn-doped hematite magnetic nanoparticles as a catalyst in degrading methylene blue using the Uv-Vis spectrophotometric method and showed excellent ability to degrade methylene blue. The percentage degradation of methylene blue using hydrogen peroxide (H2O2) added with 0%, 10% and 20% Mn doped hematite catalyst after 14 hours of reaction was 87.305%, 99.627% and 98.880%.
