Bipolar pulsing device, preparation apparatus and preparation method of chloroauric acid

Abstract

The present application relates to the technical field of fluid pulse, and discloses a bidirectional pulse device, a preparation device and a preparation method of chloroauric acid. The bidirectional pulse device is used for forming bidirectional pulse laminar flow. The preparation device of chloroauric acid comprises the bidirectional pulse device. The preparation method of chloroauric acid is realized based on the preparation device. The preparation method of chloroauric acid comprises a cyclic step executed multiple times. The cyclic step comprises a forward electrolysis step and a reverse disturbance step, and the reverse disturbance step comprises a flushing sub-step and a back-suction sub-step. The bidirectional pulse device, the preparation device and the preparation method can effectively inhibit anode passivation when electrolytic preparation of chloroauric acid is carried out by using an electrolyte system with high chloride ion concentration and low pH, so that higher chloroauric acid yield and current efficiency can be obtained even if a gold anode with lower purity is used.
