Abstract

In this work we realized the synthesis of metal (copper or silver)-ion exchanger nanocomposites
on the basis of matrices with different nature (cation, anion-exchange, geleous, macroporous). It was
obtained a special of there interaction rate between ion-exchange matrix and own metal ions solution by
help of potentiometric method. It was showed that the value of the initial deviation of their electrode
potential (in contact with solution of metal ions) from that of the compact copper electrode and during his
subsequent establishment are changing depending on the mechanism of interaction of the ion exchanger
and metal ions (ion exchange, complexation and nonequivalent absorption).
