摘要：

A method is described for the determination of selenium in various metals and alloys at concentrations of 3-100ppm. A chemical separation is made by filtration after reduction of the selenious acid to elemental selenium with hydroxylamine hydrochloride. The pure selenium product is readily analysed by X-ray fluorescence; the method is free from errors due to matrix effects. The relative standard deviation is 6 % for a copper-nickel alloy at the 60 ppm level. © 1969.
