Summary
Resins with adsorption properties for copper(II) and uranium(VI) were synthesized by crosslinking of linear polyethyleneimine and subsequent N-alkylation with dimethyl sulphate. The crosslinking agents used are: 1,9-dibromononane and 1,10-dibromodecane. The influence of the pH on the retention, maximum capacity of load and elution were studied. The morphology of the resins has been examined by scanning electron microscopy and their thermal stability by TGA.
