INTRODUCTION (abstract of doctor of Philosophy (PhD) Dissertation)
The purpose of the research based on local raw materials, it consists in the
development of the technology of obtaining complex-forming ionites containing
oxygen and nitrogen and their application.
The subject of research. The composition, structure and physico-chemical
properties of complex-forming polyfunctional ionites,
their coordination
compounds formed in the process of metal sorption are considered.
The scientific novelty of the research is as follows:
As a result of polycondensation of DMC, DMT, DHC and DHT with
orthophosphoric
acid and ammonium phosphate, effective complexing
polyfunctional ion exchangers were obtained;
on
modern equipment, the composition, structure and physico-chemical
properties of the created complex polyfunctional ion exchangers were
determined;
the optimal conditions for the purification of wastewater from ions of toxic
metals and the release of non-ferrous metal ions contained in technological
solutions were determined using synthesized complexing ion exchangers;
a technology for obtaining a complexing ion exchanger based on DMC + FA
has been developed and its technical and economic efficiency has been established.
the technical and economic efficiency of using
a complexing ion exchanger
based on DMC + FA in various industries has been studied.
