This study, Fe3O4 adsorbent coated with fulvic acid (Fe3O4-AF) was prepared from peat soil and applied to adsorb
rhodamine B dye. The optimum pH conditions of rhodamine-B adsorption on Fe3O4-AF. Fe3O4-AF adsorbent was
successfully synthesized by showing the appearance of unique FTIR spectra, namely Fe-O, O-H, C-H, C=C and
C=O groups. The crystal structure of Fe3O4-AF did not change, the surface morphology of the rigid AF colloid
attached to the Fe3O4 spherical sphere and the magnetic value of Fe3O4 decreased in the presence of AF. The
optimum conditions for rhodamine B adsorption on Fe3O4-AF occurred at pH 3 with an adsorption rate of 1.96
mg/g
