Determination of Rhenium in Molybdenum concentrates by slurry sampling total reflection x-ray fluorescence
Description
A new method was developed for the total reflection X-ray fluorescence (TXRF) determination of rhenium in molybdenum concentrates using gallium as internal standard. The samples were analyzed as slurries in Triton™ X-114. The experimental parameters, such as sample pretreatment and deposition, as well as slurry concentration, were optimized and matrix effects were investigated. Comparison with an independent method as well as the certified reference material CGL-202 were used for method validation. The method was applied to the determination of rhenium in a molybdenum concentrate from the "Elatsite-med" industrial plant located in Mirkovo, Bulgaria. The results obtained confirmed the suitability of TXRF for the fast and easy determination of rhenium in molybdenum concentrates. Key words: rhenium, molybdenum sulfide, TXRF analysis, gallium internal standard, slurry sampling
