Summary, etc. A simple route for preparation of organically modified spherical silica (SiO<sub>2</sub>) nanoparticles with CYANEX 921 has been discussed. These modified particles has been used to remove Fe<sup>3+</sup>-SCN complex from 9M phosphoric acid. SEM, XRD, IR and EDS have been used to Characterized the powder in its several stages. The effect of SiO<sub>2 </sub>weight, thiocyanate concentration, initial Fe (III) concentration, H<sub>3</sub>PO<sub>4</sub> concentration, stirring time, temperature and loaded SiO<sub>2</sub> weight have been used to study the removal percent. The loaded silica succeeded in removal of 70% of Fe (III). Langmuir isotherm model well fit the experimental data with maximum sorption capacity 45.45 mg/g. The reaction kinetic is found to follow the pseudo second order kinetic model the adsorption reaction shows exothermic behavior.
