Abstract
A process for the generation of halogens from halide-containing solutions includes the step of conducting electrolysis of the solutions in an electrolytic cell having a platinum based amorphous metal alloy anode having the formula EQU Pt.sub.p A.sub.a D.sub.d where PA0 A is Cr, Mo, W, Fe, Os, Cu, Ni, Ag, V, Au and mixtures thereof; PA0 D is B, Si, Al, Ge, P, As, Sb, Sn and mixtures thereof; PA0 p ranges from about 40 to 92; PA0 a ranges from about 0 to 40; and PA0 d ranges from about 8 to 60, with the proviso that p+a+d=100. Such amorphous metal alloy anodes are also based on the formula EQU Pt.sub.p E.sub.e F.sub.f where PA0 E is Cr, Mo, W, Fe, Os, Ir, Cu, Ni, Rh, Pd, Ag, Ti, Ru, Nb, V, Ta, Au and mixtures thereof; PA0 F is B, Al, Ge, As, Sb, Sn and mixtures thereof; PA0 p ranges from about 40 to 92; PA0 e ranges from about 0 to 40; and PA0 f ranges from about 8 to 60, with the proviso that p+e+f=100.
