There an presented results of studies on the sorption of nickel ions (in pr
esence of various quantities of NaOH) on the CBV 10A zeolite in sodium form
. The sorption of nickel ions is the result of the ion exchange reaction, a
dsorption, and precipitation on the surface of zeolite. The process should
be carried out at pH from 2 to 6 to minimize the migration of Al and Si ion
s from the zeolite skeleton into the solution.
