- Аннотация: Technologies of rare earth elements (REE) separation are once again attracting attention in view of government’s plans to restore REE industry in our country. Liquid extraction with various phosphorus containing extragents dominated in this field for decades. But the main trend in hydrometallurgy is a turn to sorption and chromatographic separations as more effective, universal and eco-friendly. The restoration of REE industry gives a good chance to build it on the basis of innovative sorption technologies. Among sorbents which can be used for this purpose chemically modified silica looks very promising. Such sorbents are widely used as stationary phases in HPLC and in biotechnology and pharma for isolation and purification of proteins, biologically active compounds, medicines, etc. There are precedents of the use of silica with attached organic ligands in hydrometallurgy, in particular, for separation of platinum metals. In this work we studied two types of silica based sorbents with chemically attached aminocarbonic and aminophosphonic ligands.
