The process of modification of the porous structure of
activated carbon impregnated with Cu (II) includes
mechanical mixing for one hour at room temperature of
a suspension of adsorbent in demineralized water with
simultaneous oxygen bubbling. As a result decreases the
surface area and micropores volume of adsorbent
Groundwater purification process of hydrogen sulfide
and sulfur by catalytic oxidation includes the addition in
groundwater of activated carbon impre-gnated with Cu
(II) modified porous structure according to the abovementioned
process, mechanical mixing of coal-water
suspension for one hour at room temperature with
simultaneous oxygen bubbling, with subsequent
separation of purified water from activated carbon for a
possible reuse in a new cycle of purification
