Sorption X-ray fluorescent determination of gold and platinum in natural mineral objects with application of polymer chelate sorbent

摘要

For selective separation, concentration, and X-ray fluorescent determination of n centre dot 10~(-4) percent amount of Pt and Au in mineral objects, a new sorbent - polystyrene-azorhodanine - has been synthesized and analytically investigated. The complex technique of Pt and Au concentration from sulfide ores and silicate rocks with the help of this sorbent and following application of X-ray fluorescent analysis was developed.
