title: Study on adsorption of Co(II) and Ni(II) onto mesoporous Ti-containing MCM-48.
abstract: Ti-containing MCM-48 (Ti-MCM-48) material with mesoporous structure was synthesized and characterized, and the absorption processes of Co(II) and Ni(II) on the material were investigated in detail in the present study. The Ti- MCM-48 was synthesized by hydrothermal reaction and characterized by XRD, FT-IR and nitrogen sorption methods. Optimum pH value for maximum adsorption rate is 8.0, and the saturated adsorption capacities of Ti-MCM-48 for Co(II) and Ni(II) are 9.870 and 22.94 mg g(-1) respectively, which are greater than those of the reported materials Adsorption isotherms of Co(II) and Ni(II) on Ti-MCM-48 accord well with the Langmuir adsorption models. Kinetic data of adsorption reactions and the adsorption equilibrium parameters were also determined, and the obtained data correlated linearly with the pseudo-second order equation.
