Method for purifying antimony chloride solution through arsenic removal

Abstract

The present disclosure belongs to the technical field of purification, and particularly relates to a method for purifying an antimony chloride solution through arsenic removal. The method includes: 1) adding copper-antimony alloy into a crude arsenic-containing antimony chloride solution to be treated in a protective atmosphere to obtain an antimony chloride solution containing low-concentration arsenic impurities after a reaction; and 2) performing distillation and concentration on the antimony chloride solution containing low-concentration arsenic impurities to obtain a high-purity antimony chloride solution. According to the present disclosure, the technical difficulty of removing impurity arsenic in a preparation process for high-purity antimony is solved, distillation is carried out under the condition of a low temperature, the operation is simple and low in energy consumption, and the technological process for preparation is simple, high in production efficiency, easy to realize, free of industrial pollution and therefore, suitable for industrialization.
