| Abstract: |
| A method for the determination of silver in tin anode slim by flame atomic absorption spectrometry (FAAS) was developed. The effects of media and acidity on the determination were investigated. Under the selected conditions, the impurities such as tin, antimony and lead in tin anode mud did not interfere with the determination of silver. Values of recovery were in the range of 99.2％ to 103％ and the result of precision test showed that RSD(n=11) was less than 4%. This method is simple and can meet the testing requirements for daily analysis of impurity elements in tin anode slime. |
