title: A chemical concentration x-ray determination of selenium in copper-, nickel-and iron-base alloys.
abstract: 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.
