NEW COMPLEXONE DERIVATIVES OF 8-HYDROXYQUINOLINE AND THEIRS APPLICATION IN UO2 2+ EXTRACTION

Fatiha Zaoui, Didier Villemin, Nathalie Bar, Mohamed Amine Didi.




Abstract

New complexone derivatives of 8-hydroxyquinoline (quinolinol) were synthesized by the Mannich reaction from secondary and primary
amines. Our syntheses were carried out either at room temperature, at reflux or under microwave irradiation, in good yields. The use of the
7-(dioctylamino) methyl) quinolin-8-ol (3f) as new extractant for the uptake and removal of UO2
2+ was investigated. Conditions for an
effective sorption were optimized. The total sorption capacity was 102 (mg.g-1) under optimum experimental conditions.

Key words: Multicomponent Mannich reactions; microwave irradiation; 7-(alkylaminomethyl)quinolin-8-ol type complexones; uranylion extraction; 7-(dioctylaminomethyl)quinolin-8-ol.
