The scientific bases of extraction of inorganic compounds and creation of extraction schemes.

On the base of local raw the extraction reagents with the functional groups have been synthesized, their physicochemical properties have been examined. Extraction of a number of the elements depending on various factors: concentration of studied metals and extragents, relation of water and organic phases have been studied by physicochemical methods the composition of obtained compounds has been defined, and synergetic effect has been calculated. Synthesized extragents are applied for clearing the sewage from dyers, mercury, and phenol and for isolating ammonia compounds of heavy metals in the process of lixivication from model and industrial solutions. On the basis of the results obtained there has been worked out an extraction scheme of selective extraction of metals from complex mixtures that was tested on pilot industrial plant.
