Method for measuring arsenic content in copper electrolyte through reduction separation

The invention relates to a method for measuring arsenic content in copper electrolyte through reduction separation, which comprises the following steps: (1) transferring copper smelting copper electrolyte into a beaker, firstly adding pure water, then adding hydrochloric acid, adding solid sodium hypophosphite for several times under continuous shaking until the yellow-green color of the solution fades, then adding 2g of excessive sodium hypophosphite, and uniformly mixing; keeping the temperature of the sample in a boiling water bath, then slightly boiling and cooling; (2) placing a funnel on the opening of the conical flask, washing the funnel, and filtering the test solution and precipitate by using the funnel with absorbent cotton and filter paper; washing precipitates on the original beaker and the degreasing cotton; washing the precipitate until the filtrate is neutral; (3) transferring the precipitate together with the absorbent cotton and the filter paper pulp into an original conical flask, and washi
