Abstract The diimine bridged mesoporous silica (PMOS) was synthesized by copolycondensation method with CTAB/PAANa as mixed template, tetraethyl orthosilicate as silicon source and homemade silane coupling agent as modifier. The structure and morphology of PMOS materials were characterized by FTIR, XRD, BET, solid-state nuclear magnetic and TEM. The effects of pH value, mass rations of adsorbent and absorption time on adsorption for Cr(Ⅵ) were discussed. Besides, the adsorption behavior of PMOS for Cr(Ⅵ) was mainly investigated. The results showed that PMOS was highly ordered mesoporous structure. While pH=6, the concentration of initial solution was 200 mg/L, adsorption time was 8 h, the PMOS showed excellent adsorption for Cr(Ⅵ). The adsorption could be described by Langmuir model and pseudo-second order kinetics model. When the temperature was 45 ℃, the sa-turated adsorption for Cr(Ⅵ) was 428.61 mg/g. The force between PMOS and Cr(Ⅵ) is mainly electrostatic force and coordination force.
