| Abstract: |
| Recent progresses on developing analytical methodologies for determining precious metals in secondary resources，including sampling methods，samples pretreatment, and testing techniques, were reviewed in this paper. The applications of sample pretreatment techniques (fire assay method, acid dissolution method, alkali fusion) and testing techniques (gravimetric method, volumetric method, spectrophotometry method, atomic absorption spectrometry, emission spectrometry methods, electrochemical method) in precious metals analysis were introduced in detail. Finally, some suggestions and a perspective on development of method for the determination of precious metals in secondary resources were also given. |
