Adsorption of dyes on mesoporous carbons

100%
EN
Mesoporous carbonaceous materials were synthesized by applying the method of impregnation of mesoporous silica being the pore creating template. The isotherms of adsorption of methylene blue and methyl orange were measured from aqueous solutions. The kinetics of methylene blue adsorption was studied. The adsorption isotherms and kinetic dependence were discussed.
EN
The temperature dependence of o-Ps lifetime in the pores calculated from extended Tao-Eldrup model was compared to the experimental data, collected for a set of silica gels synthesized using the polymer template technique. For the sample with average pore radii 2.0 nm rather good agreement between the model and experiment was found. For the sample with narrow pores (near 1.0 nm) the lifetime spectrum was complex. Except the range of highest temperatures the lifetimes are far from model calculations.
