Abstract
The article considers an actual but not
sufficiently developed problem of attractiveness for the
subjects of entrepreneurial activity of adsorption
extraction of Nickel ions (II) by bentonite clays. The
basic social and psychological mechanisms for the
adoption of environmentally-oriented activities are
analyzed. The styles of entrepreneurs’ response to the
attractiveness of adsorption extraction of Nickel ions (II)
by bentonite clays are characterized. The process of
sorption of Nickel ions (II) with a fixed layer of sorbent
by bentonite clays is investigated. The main advantages
of using bentonites in water treatment technologies are
described: powerful geological reserves, cheap rock
formation, simple preparation for transportation and use,
the possibility of using spent sorbents in other
technologies, eliminating the need for expensive
regeneration. The influence of different factors (length
of the process, layer of the adsorbent) on the degree of
wastewater treatment from Nickel ions, influence of
pumping speed on dynamic capacity of the sorbent is
investigated and effective volume is determined.
The results of the research indicate that the use of
natural mineral sorbents, in particular, the bentonite clay
of Cherkassy deposit, is promising and effective for
purification of waste water from Nickel (II) ions.
