Chemically active mesoporous silica was prepared via grafting of N-(3-triethoxysilylpropyl)-4,5-dihydroimidazole. Binding behavior of the adsorbent toward Pt(II) and Pd(II) ions was investigated. In addition, the properties of the adsorbent, such as pore structure and pore uniformity, were also examined. Results showed that the adsorbents developed in this study have high affinity for noble metal ions, such as Pt(II) and Pd(II), in aqueous solutions.
