Chemical thermodynamics and thermochemistry
Reasoning from the physico-chemical modelling for leaching technogenic deposits,
containing nepheline under anthropogenic precipitation influence, one managed to
determine the conditions for composing second minerals (gibbsite, kaolinite,
analcinite, natrolite) and water complexes (Na, Al, Si), allowing to make forecast of
ecological consequences caused by long keeping the industrial wastes from treating
factories and then to upgrade technological processes while making second
processing.
Chemical technology of nature water and wastes.
The Institute introduced an efficient way for doing less harmful radionuclide solutions by
immobilization them in hardly soluble compounds -the products of polymerisation
of hardening dispersions (geopolymeric adsorbents) and adsorbents from nature
minerals (Joint with Institute of chemistry, KSC, RAS)
Adsorption and adsorbents
There was created technological regiment for radionuclides' immobilization, using
metallurgical slimes of magnesium-iron content and vermiculite as hardening
mineral dispersions.
