MATERIALS AND METHODS FOR THE SEPARATION OF COPPER IONS AND FERRIC IRON IN LIQUID SOLUTIONS |
摘要 |
A silica-polyamine based extraction material selectively removes copper from low concentration, low pH leach solutions separating copper from ferric iron or chloride 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 picolychloride is attached. Typically the silica is silica gel, and hydro-carbylsilyl covently bound to the silica gel surface s formed from the silanization of hydrated silica gel with trifunctional silane. The resulting product is a durable, high capacity extraction material that is selectively captures copper at high flow rates and releases that copper into highly concentrated solutions. |
