摘要
以镍作为基体改进剂 ,可使银的灵敏度提高约一倍 ,加入柠檬酸也会使银的灵敏度提高。石墨炉原子吸收法测定高温镍基合金中痕量银 ,相对标准偏差为 6 .7% ,回收率为 97.5 %～ 10 4 .0 %之间 。
The sensitivity of Ag can be enhanced about one time when Ni is used as a matrix modifier, and adding citric acid can also enhance the sensitivity of Ag. It is simple and quick to determine trace Ag in the high temperature Ni-based alloy using the graphite furnace atomic absorption spectrophotometry , the relative standard deviation is 6.7%, and the recovery rate is between 97.5%～104.0%.
