Abstract:This method adopts the mixture of aluminium oxide,potassium pyrosulfuric acid,sodium fluoride and graphite powder as buffer,germanium as internal standard element,one-time sampling,vertical electrode emission spectrometry and simultaneously measurement of copper,lead and zinc.The detection limit,precision and accuracy can all meet the requirements of geochemical exploration samples.This is a convenient,quick and economic spectrum analysis method.
Keywords:emission spectrometry  geochemical exploration samples  Cu  Pb  Zn
