Abstract EN
The incorporation of rhodamine B into polyurethane foam matrix was prepared by mixing the rhodamine B with polyol (polyether) prior to the addition of diisocyanate reagent to form the polyurethane foam material.
Rhodamine B grafted polyurethane foam (Rod.B-PUF) was found to be very suitable for the separation and preconcentration of trivalent metal ions e.g.
bismuth (III), antimony (III) and iron (III) from thiocyanate solutions.
Bismuth and antimony were separated from concentrated acid medium (1–6 MH2SO4).
Iron (III) was separated from pH 1 to 3.
The kinetics of sorption of the Bi (III), Sb (III) and Fe (III) onto the Rod.B-PUF was found to be fast, the extraction is accomplished from 5 to 10 min with average values of half-life of sorption (t1 / 2) of 2.9 min.
The average values of the Gibbs free energy (DG) for the sorption of metal ions onto Rod.
B-PUF are kJ mol1 which reflect the spontaneous nature of sorption process.
The sorption mechanism of the metal ion onto Rod.
B-PUF was also discussed.
