"Methylene blue is a dye that is widely used in the batik industry, this has the potential to cause environmental problems considering the residual methylene blue content in liquid waste is difficult to decompose naturally. This study aims to synthesize modified magnetite nanoparticles using sweet orange peel extract (MNPs-CS) from household waste and its application as an adsorbent of methylene blue dye in a multicomponent system. The synthesis of MNPs-CS was carried out by the reverse coprecipitation method with water solvent at a temperature of 60°C. MNPs-CS were characterized using FTIR, XRD, and SEM-EDX. In this study, the adsorption of methylene blue by MNPs-CS was studied at various pH, reaction time, and concentration to determine the kinetic model, adsorption isotherm, and interactions that occur between methylene blue on MNPs-CS. FTIR spectrum and XRD diffractogram showed that the magnetite formed in a pure state was not mixed with other iron oxides. SEM images showed irregular morphology with a rough surface. EDX spectrum showed that the magnetite nanoparticles in this study were successfully coated by sweet orange peel extract. The crystal and particle sizes of MNPs-CS was 7,09 nm and 1-14,79 μm. The optimum adsorption of methylene blue on MNPs-CS occurred at pH 10 and a time of 30 minutes, and followed the pseudo second-order Ho kinetic model. The isotherm model that is suitable for the adsorption of methylene blue in single and multicomponent systems is the Freundlich isotherm model. Methylene blue and MNPs-CS are thought to interact through π-π interactions, electrostatic interactions, and hydrogen bonds."^^ . "2025-03-04" . . . . "UIN SUNAN KALIJAGA YOGYAKARTA"^^ . . .
