Removal of Phenol Using Rice Husk Doped Iron Oxide Nanoparticles with Performance, Characterization, Kinetic & Isotherm Study from Waste Water

The effluent containing phenol 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 phenol from the aqueous solution. Batch adsorption tests for the removal of phenol from synthetic phenol 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 Phenol was removed. The RH+Fe adsorbent data were best fitted for Langmuir isotherm and had an adsorption capacity of 90 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 phenol elimination adsorbent.
