The study adsorption of copper ions and lead by bentonite clays Zyriansky deposits as a function
of contact time, pH and temperature. It is established that silanol and alyuminolnye groups clays are
involved in ion exchange and complex formation with heavy metal ions in the dependence by pH
dominates a particular process. Studied the process adsorption of ions of copper and lead from equimolar
binary solutions. With increasing temperature from 293 K to 333 K adsorption of ions on the clay
increases.The nature of the sorption isotherms is independent of temperature in the selected interval.
Proposed mechanisms of ion sorption Cu (II) and Pb (II)
