Studi Isoterm, Termodinamik Dan Kinetika Adsorpsi Zat Warna Direct Brown Meng…

Dye waste produced by industries contains dangerous and poison materials that could pollute the environment. In this study, hydroxyapatite calcium deficient will be used as medium of adsorption. This process will determine the isotherm models, thermodynamic, and adsorption kinetics models. The dye adsorption process was carried out at various temperatures and initial concentration of dye at…
