Determination method for silver in copper removal slag of copper anode mud wet treatment technology

The invention discloses a determination method for silver in copper removal slag of a copper anode mud wet treatment technology. The determination method comprises the following steps: adding tartaric acid and nitric acid into copper removal slag, heating to slightly boiling, carrying out digestion, filtering and washing filter residue, so that filtrate and the filter residue are obtained; transferring the filter residue into a crucible, adding aqua regia, heating to slightly boiling, carrying out digestion and concentration, filtering and washing filter residue, so that the filtrate and filter residue are obtained; respectively determining silver contents of the filtrate obtained through digestion twice, and combining the obtained results as the content of silver in raw materials. The tartaric acid is added as a masking agent, so that interference of co-existing ions such as Fe, Pb and Zn can be eliminated; nitric acid is added in batches, so that complete digestion can be facilitated; and diluted nitric aci
