Reducing elution method for copper(II) in cation-exchange chromatography by hydroxylamine hydrocloride solution.
The cation-exchange Chromatographic behaviour of copper and several other metals in hydroxylamine hydrochloride solution has been investigated. At 50 degrees copper(II) is reduced to copper(I) which is eluted quickly in a narrow band and easily separated from other metals such as zinc, nickel, cobalt and iron.
