摘要：

A kinetics equation for topochemical reactions is obtained and used to analyze processes of the sorption of heavy-metal ions by sorbents based on nanostructured synthetic aluminosilicates (i.e., ion-exchangers whose mechanism of sorption is associated with ion exchange) while sorption isotherms are described by the Langmuir equation. It is established that the experimental results on the kinetics in all the investigated cases differ by negligible deviations from those obtained according to the proposed equation throughout the period of analysis.
