DETERMINATION OF SILVER-BORON-TIN FROM MULTI-PURPOSE REGIONAL GEOCHEMICAL SURVEY BY EMISSION SPECTROMETRY

In order to determine the elements of Ag, B and Sn from the multi-purpose regional geochemical survey with emission spectrometry, we adopt the mixture of K₂S₂O₇, NaF, Al₂O₃ and carbon powder as solid buffer, Ge as internal standard, and blend the samples and buffers in the graphite electrode in a quality ratio of 1:1. This paper analyzes and summarizes the problems raised in the test and puts forward countermeasures. The method has obtained good results in practices.
