| Abstract: | Summary Resins with retention properties for copper(II) and uranium(VI)were synthesized by crosslinking of polyethyleneimine with 1,9-dibromononane and 1,10-dibromodecane, and subsequent alkylation with dimethylsulphate. The effect of the pH on the retention, elution assays in acid and basic medium, and maximun capacity of load were determined. Moreover, the thermal behaviour was studied. |
