Oxidn. of Tl(I) to Tl(III) in the presence of halide ions and transition-metal compds. was improved to decrease the process temp. and pressure while increasing the Tl(III) yield by using 0.05-0.3M heteropoly acid (HPA) as the transition-metal compd. in 2-10:1 HPA-Tl ratio, and to accelerate the process by adding Br in 2-100:1 Br-Tl ratio and acid to pH 0-1.0.
