Abstract

The copper (II) sorption research results from CuSO4 aqueous solutions with composite sorbent
based on cation exchanger CU-2×8 and iron (III) hydroxide were represented, the distribution coefficients
to metal ion under investigation were computed. It was determined that Langmuir model describes the
sorption process; specific surface of the ion exchanger was defined. The ion exchange kinetics was
studied, the gel diffusion coefficient of copper (II) ion was calculated.
