چکیده
|
Noncrystalline,high surface area magnesium silicate gel was successfully prepared by hydrothermal method. such product was characterized by bet and xrd to determine surface area 576.4 m2·g-1,average pore width 2.76 nm,and amorphous surface. the adsorption behaviors of basic brown and chrysophenine on magnesium silicate gel were investigated through changing initial concentration,adsorbent dosage,solution ph,contact time,and temperature. the experimental data was analyzed by the adsorption isotherms and kinetics. the results showed the adsorption progress was fast for basic brown,and the adsorption equilibrium was finished in 2 h,while the adsorption equilibrium of chrysophenine was finished in 7 h. freundlich isotherm model and second-order kinetic models described the adsorption process very well. © 2015 zhun zhao et al.
