Properties of new fibrous adsorbents with amidoxyme and hydrazidine groups

Data on sorption properties of new fibrous adsorbents with respect to heavy metals are presented. The POLYORGS 34 and POLYORGS 35 filled fibrous adsor bents and POLYORGS 33 fibrous adsorbent contain amidoxyme and hydrazidine g roups. Is has been shown that these adsorbents can be used for the adsorpti on preconcentration of heavy, noble, and rare metals and radionuclides from aqueous salt solutions. Examples of using adsorbents under study for the d ynamic preconcentration of copper from a 0.5 M NaCl solution during filtrat ion through a series of disks, column, or adsorption cartridges are present ed.
