Abstract: As a precious scattered metal element,germanium has been widely used in modern high technology industries.In this paper,the pretreatment method and the advances on instrumental analysis of trace germanium in samples in recent years were reviewed.The effect of pretreatment method on the determination of trace germanium was introduced including dissolution by electric hot plate,microwave digestion and digestion in closed tank.The instrumental analysis methods for determination of trace germanium in recent years were summarized,such as inductively coupled plasma atomic emission spectrometry (ICP-AES),atomic absorption spectrometry (AAS),atomic fluorescence spectrometry (AFS),inductively coupled plasma mass spectrometry (ICP-MS),spectrophotometry,electrochemical method and ion chromatography and so on.The characteristics and application ranges of these methods were discussed.Moreover,the development direction of pretreatment and analysis method of trace germanium was prospected.
