摘要
先用硝酸和盐酸溶解铜阳极泥 ,再加浓氨水使其转换成氨性溶液 ,最后用原子吸收分光光度法测定铜阳极泥中的银 .本法测定结果与 YS/T88— 1995火试金法测定结果一致 ,相对标准偏差为 1.15 % (n=6 ) .本法可快速、准确地测定铜阳极泥中的银 .
Copper anode mud was first dissolved with nitric acid and hydrochloric acid, then concentrated ammonia water was added into the resultant to convert it into ammoniac solution in which silver from the coper anode mud was determined by atomic absorption spectrophotometry. The results from this method were in conformity with those from YS/T88-1995 method, with the relative standard deviation being 1\^15% after 6 parallel determinations. The method is suitable for rapid and accurate determination of silver in copper anode mud.
