Abstract

Atomic absorption spectroscopy is a rapid and convenient method for the determination of silica and alumina in silicate rocks. NaOH fusion of the samples in nickel crucibles is more complete and superior to NazCOa fusion in platinum. Non-resonance light absorption within the flame has been eliminated by: a) reduction of the solution feed-rate to about 75To… (More)
