In this research, modified zinc ferrite nanoparticle by 3-amino propyl triethoxysilane was synthesized and its dye removal ability was studied. The synthesized adsorbent was characterized using Fourier Transform Infrared and Scanning Electron Microscopy. Acid bule 25 (AB25), Direct green 6 (DG6) and Direct red 23 (DR23), were used as model compounds. The effect of operational parameter such as adsorbent dosage, pH, dye concentration and salt was evaluated. The isotherm and kinetic of dye adsorption were studied. The maximum dye adsorption capacity (Q0) of adsorbent for AB25, DG6 and DR23 was 333 mg/g, 53 mg/g and 167 mg/g, respectively. It was found that dye adsorption onto adsorbent followed with Langmuir isotherm. Adsorption kinetic of dyes was found to conform to pseudo-second order kinetics. The results showed that the modified zinc ferrite nanoparticle being a high dye adsorption capacity might be a suitable adsorbent.
