Аннотация
The kinetics of adsorption of Rb+ and Cs+ ions on different non-polarized and polarized active carbons at temperatures of 25, 35, 45, and 65 °C was investigated. The obtained results were processed using the equations of the pseudo-first- and pseudo-second-order models. The pseudo-second-order model better describes the adsorption of alkaline metal ions on the carbons studied. The kinetic dependences of three types reflecting heterogeneity of the sorbent surface were revealed on the basis of the theoretical analysis of sorption systems.
