Determination of gold by X-ray fluorescence methods.
X-ray fluorescence methods for the determination of gold in silver beads and in hydrochloric acid solutions are described. These techniques may be applied to silver containing 0.2-5 % of gold and to solutions containing 0.004-0.1% of gold. Platinum, palladium, rhodium and indium do not interfere.
