| Abstract: | A novel method about the recycling and reuse of silver waste liquor comes from laboratory was put forward.This method is composed of several procedures,including precipitation with sodium chloride, dissolution in ammonia,(electrolysis) and preparation of silver nitrate.The percent recovery and the purity of recovered silver is 96.5% and(99.90%) respectively.The final product of silver nitrate can be reused in the analysis experiment determination. |
