Abstract

Silica gel was modified with N-[3-(Trimethoxysilyl)propyl]ethylenediamine, following grafted with ethylenediaminetetraacetic acid (EDTA). The functionalized silica gel was used to readily absorb Co(II) ion from aqueous solution forming SG-Co, via the coordination of EDTA group on the surface of silica gel. The adsorption of Reactive Brilliant Red X-3B (X-3B) in aqueous solution with SG-Co was investigated under varying time, dye concentration, and adsorbent dosage. The results showed that the adsorption capacity of SG-Co for X-3B increased with increasing of time, initial concentration of the dye solution, and absorbent dosage. The adsorption process followed a pseudo second-order model and experimental data fitted Langmuir adsorption model.
