Separation of Ga3+ from a Ga3+–Al3+ solution using a long-chain alkylated cupferron membrane
Abstract
A porous membrane impregnated with a long-chain alkylated cupferron [N-(alkylphenyl)-N-nitrosohydroxylamine ammonium salt] kerosene solution almost completely concentrated Ga3+ from a Ga3+–Al3+ binary solution against the concentration gradient, the counter flow of H+ providing the driving force.
