Recovery of platinum from leaching solutions by interaction with porphyrins
Two differently substituted base porphyrins, one containing aliphatic unsaturated groups and one functionalized with basic effect at the periphery: 5,10,15,20-tetrakis-(4-allyloxyphenyl)- porphyrin and 5,10,15,20-tetrakis-(4-aminophenyl)-porphyrin, were investigated for their capacity to complex wit...

| Tartalmi kivonat: | Two differently substituted base porphyrins, one containing aliphatic unsaturated groups and one functionalized with basic effect at the periphery: 5,10,15,20-tetrakis-(4-allyloxyphenyl)- porphyrin and 5,10,15,20-tetrakis-(4-aminophenyl)-porphyrin, were investigated for their capacity to complex with hexachloroplatinic acid from leaching solutions. Their different nature makes them interact differently with the hexachloroplatinic acid in solution, as aminophenylporphyrin is more capable to form more stable complexes, therefore it is suitable for the recovery of platinum from diluted solutions (removal capacity is large 86.6 %) whereas the amount of platinum that can be recovered by allyloxyphenylporphyrin is lower, only 74.07 %. |
