Notes:
Weak and strong basic resins were synthesized by crosslinking with 1,7-dibromoheptane and 1,12-dibromododecane and subsequent N-methylation reaction of branched and linear polyethyleneimine. All the resins are insoluble in water. It was found that the N-methylated resins showed the highest retention ability for uranium. The resins do not retain significatively iron (〉 10%), and only two of them retain copper above 80% at optimum pH. Elution assays with sulphuric acid, sodium carbonate, and thermal stability were also carried out.
