摘要: Abstract A hydride-generation flameless atomic-absorption technique is used to determine as little 5 ng g-1 tellurium in 0.25 g of silicate rock. After acid decomposition the sample, hydride generated with sodium borohydride and vapor passed directly a resistance-heated quartz cell mounted an spectrophotometer. Analyses 11 U.S. Geological Survey standard rocks are presented.
