Abstract:

The different pre-treatment methods,the post methods of analyzing germaniumcontent and their principles,the applicable conditions and the scope of the various germanium-containing raw materials were summarized.The advantages and problems of traditional methods were also introduced.It was pointed out that the difficulty of the current method of analyzing the content of germanium lies in the extremely low actual germanium-containing raw materials,the complexity of the composition and the presence of interfering elements.The improvement and development direction of the germaniumcontent analysis method were prospected：a）The traditional method,including some detailed operations,requires more experience. Simple,high-precision,high-efficiency,non-toxicity and no environmental pollution are the main development directions of germanium analysis methods in the future;b）Combining different pre-processing methods with post-analysis methods,sometimes multiple methods can be combined to analyze,reducing the errors caused by experiments;c）Analytical methods should not be limited to laboratories,but should be extended to actual production;d）Aiming at the problem of too many coexisting interfering elements other than germanium in complex germanium-containing raw materials,on the one hand,a more appropriate pre-treatment method needs to be adopted to separate germanium from coexisting interfering ions,and on the other hand,it is necessary to improve the anti-interference ability of the elements in the analysis method.

Key words: analysis of germanium content, pre-treatment, post analytical method
