Abstract
Oxine ligands placed on styrene base ion exchange resins selectively remove iron and gallium from acidic solutions. After loading, the oxine resin is stripped of the loaded metals and used again for further metal removal. The resins can be used for process streams, acid rock drainages, or any other iron or gallium containing solution.
