Materials and methods for the separation of copper ions and ferric iron in liquid solutions |
| abstract |
A silica-polyamine based extraction material removes selected transition metal ions from solution in the presence of iron ions. The silica-polyamine base is a reaction product of a polyamine and a covalently anchored trifunctional hydrocarbylsilyl that yields non-crosslinked amino groups to which pyridine function group is attached. The extraction material is particularly useful in selectively removing copper from low concentration, low pH leach solutions separating copper from ferric iron or chloride ions. The product is a durable, high capacity extraction material that selectively captures copper at high flow rates and releases that copper into highly concentrated solutions. |
