Abstract

The role of some common acids CH₃COOH, HCl, HNO₃, H₃PO₄ and H₂SO₄ in the multi-metal distribution/extraction of Cadmium, Nickel, Lead and Iron from aqueous media buffered to either pH 4.75 or 7.5 using the ligand 4´4-(1E,1E´)-1,1´-(ethane-1,2-diylbis(azan-1-yl-1ylidene))bis(5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-ol) H₂BuEtP alone and in the presence of 1-(3-hydroxy-5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl) butan-1-one (HBuP) was studied using solvent-solvent extraction method. An equilibration time of 60 minutes was used. The extraction raffinates were analysed for Cadmium, Nickel and Lead with an Atomic Absorption Spectrophotometer (AAS) while Iron was colorimetrically determined with 1,10-phenanthroline and absorbances compared with standards and extraction parameters; distribution ratios, percentage % E and number of batches n needed to achieve 99.9% extraction of the four metals calculated. The distribution ratios of the metals were statistically analysed for differences between the two buffers, organic extractants and the acids. All the acids showed good potentials in the selective separation of Iron from Cadmium, Nickel and Lead. The conditions for the use of the different acids for the selective separations of Cadmium/Iron from Nickel/Lead, Nickel/Iron from Cadmium/Lead and Lead/Iron from Cadmium/Nickel were established with calculated number of batches needed to obtain 99.9% extractions of the metals. Only 0.01 M – 0.05 M H₃PO₄ showed good potentials in the mult-imetal extraction of the four metals from an aqueous medium containing the four metals and buffered to pH 7.5 using the mixed ligands H₂BuEtP/HBuP organic phase and 99.9% extraction of the four metals calculated to be achievable after 9 batches of extractions with fresh organic phase. The synergic effect of the second ligand HBuP was observed in only a few cases.

The conditions for the use of the different acids for the selective separations of Cadmium/Iron from Nickel/Lead, Nickel/Iron from Cadmium/Lead and Lead/Iron from Cadmium/Nickel were established with calculated number of batches needed to obtain 99.9% extractions of the metals. Only 0.01 M – 0.05 M H3PO4 showed good potentials in the mult-imetal extraction of the four metals from an aqueous medium containing the four metals and buffered to pH 7.5 using the mixed ligands H2BuEtP/HBuP organic phase and 99.9% extraction of the four metals calculated to be achievable after 9 batches of extractions with fresh organic phase.

AB  - The role of some common acids CH3COOH, HCl, HNO3, H3PO4 and H2SO4 in the multi-metal distribution/extraction of Cadmium, Nickel, Lead and Iron from aqueous media buffered to either pH 4.75 or 7.5 using the ligand 4´4-(1E,1E´)-1,1´-(ethane-1,2-diylbis(azan-1-yl-1ylidene))bis(5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-ol) H2BuEtP alone and in the presence of 1-(3-hydroxy-5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl) butan-1-one (HBuP) was studied using solvent-solvent extraction method. An equilibration time of 60 minutes was used. The extraction raffinates were analysed for Cadmium, Nickel and Lead with an Atomic Absorption Spectrophotometer (AAS) while Iron was colorimetrically determined with 1,10-phenanthroline and absorbances compared with standards and extraction parameters; distribution ratios, percentage % E and number of batches n needed to achieve 99.9% extraction of the four metals calculated. The distribution ratios of the metals were statistically analysed for differences between the two buffers, organic extractants and the acids. All the acids showed good potentials in the selective separation of Iron from Cadmium, Nickel and Lead. The conditions for the use of the different acids for the selective separations of Cadmium/Iron from Nickel/Lead, Nickel/Iron from Cadmium/Lead and Lead/Iron from Cadmium/Nickel were established with calculated number of batches needed to obtain 99.9% extractions of the metals. Only 0.01 M – 0.05 M H3PO4 showed good potentials in the mult-imetal extraction of the four metals from an aqueous medium containing the four metals and buffered to pH 7.5 using the mixed ligands H2BuEtP/HBuP organic phase and 99.9% extraction of the four metals calculated to be achievable after 9 batches of extractions with fresh organic phase. The synergic effect of the second ligand HBuP was observed in only a few cases.
