Abstract
New sorption filters containing conformationally flexible amino-carbox ylic groups were proposed for preconcentration of metals. Quantitative recovery of metals was achieved in a dynamic regime at a solution flo w rate up to 4 ml . min(-1) . cm(-2) in a pH range 3-8 from solutions with high salt content and in the presence of natural complexing agent s. The dynamic capacity of DETATA-filters of the heavy metals was inve stigated. XRF and ICP-AES methods of heavy metals determination after preconcentration on the filters were developed.
