Abstract: The effluent containing dye is one of the major health concerns for humans and the environment. Iron oxide nanoparticle (Fe NPs) has properties like size, large surface area, and magnetic nature that were more impressive for removing dye from the aqueous solution. Batch adsorption tests for the removal of dye from synthetic dye water were done in the current work, and the modified iron oxide nanoparticle with rice husk ash (RH+Fe) was confirmed by characterization techniques like XRD, FTIR, SEM, and particle size analysis. Using 2.6 g/L, 50 °C, and 10 ppm of adsorbent dosage, starting concentration, and temperature of RH+Fe, 96 % of the dye was removed. The RH+Fe adsorbent data were best fitted for Langmuir isotherm and had an adsorption capacity of 98 mg g-1 . In the kinetic investigation, the regression coefficient of pseudo-second order was determined to be 0.96. The results of the current investigation offer a promising dye elimination adsorbent.
