Solvent Extraction of Zinc (II)‎ and Manganese (ii)‎ with 5, 10, 15, 20 tetrapheny l-21h, 23h-porphine (tpp)‎ through the metal exchange reaction of lead (ii)‎-tpp

الملخص EN

An investigation was carried out on the extraction of aqueous Zn (II) and Mn (II) with a hydrophobic porphyrin (5, 10, 15, 20-tetraphenyl-21H, 23Hporphine, TPP) through a metal exchange reaction of Pb (II)-TPP.

The distribution ratios (D) of these metals were found to be independent of the Pb (II) concentration in the aqueous phase.

Pb (II) in the aqueous phase acted as a catalyst which promoted the metal-TPP complexation.
