Heavy Metals Removal in Aqueous Solution by two Delta-diketones
D. Fanou, B. Yao, S. Siaka and G. Ado

Abstract:
This research presents the elimination of lead, coppers, zinc and iron by complexation with δ-diketones particularly, 1, 3, 5-triphenylpentane-1,5-dione and 3-furyl-1,5-diphenylpentane-1, 5-dione in liquid biphasic system (water/dichloromethane). Various factors (pH, nature and concentration in metal ions, time of contact, chelating capacity and temperature) influencing this interaction were examined. The use of these molecules in the complexation optimal conditions (Temperature = 35°C, Mass ratio Cmetal/Cextractant = 4, Contact time = 30 min and pH 4), led to the elimination of more than 70% of lead, iron, coppers and zinc.
