| Abstract: | Data on sorption properties of new fibrous adsorbents with respect to heavy metals are presented. The POLYORGS 34 and POLYORGS
35 filled fibrous adsorbents and POLYORGS 33 fibrous adsorbent contain amidoxyme and hydrazidine groups. Is has been shown
that these adsorbents can be used for the adsorption preconcentration of heavy, noble, and rare metals and radionuclides from
aqueous salt solutions. Examples of using adsorbents under study for the dynamic preconcentration of copper from a 0.5 M NaCl
solution during filtration through a series of disks, column, or adsorption cartridges are presented. |
