Successfully of asamhumat modification in magnetite indicated by result of determining the functional group content of Fe34has decreased compared to the results of determining the functional group content of humic acid. The interaction of Fe34with optimumblueindigosol O4B dye at pH 5 and optimum time of 45 minutes followed the pseudo first order reaction kinetics according to Lagergren with the adsorption rate constant 0.0047. The adsorption isotherm model follows the Langmuir isotherm model with an adsorption capacity 1,234 mmol gFe34adsorbs 1,234 mmol blue indigosol O4B. O-AH O-AH -1 which means that every 1 gram of O-AH Fe34, adsorption, blue indigosol O4B date: 2018-07-15 date_type: published pages: 73 institution: UIN SUNAN KALIJAGA YOGYAKARTA department: FAKULTAS SAINS DAN TEKNOLOGI thesis_type: skripsi thesis_name: other citation: Rafida Ati Fauzi, NIM. 14630032 (2018) ADSORPSI ZAT WARNA INDIGOSOL BLUE O4B MENGGUNAKAN ASAM HUMAT TERMODIFIKASI MAGNETIT (Fe3O4).
