The preparation, certification, and characterization of two new biological certified reference materials for inorganic trace analysis have been presented. They are based on different varieties tobacco leaves, namely, Oriental Basma Tobacco Leaves (INCT-OBTL-5), grown in Greece, Polish Virginia (INCT-PVTL-6), Poland. Certification the was statistical evaluation results obtained a worldwide interlaboratory comparison, which 87 laboratories from 18 countries participated, providing 2568...
Abstract The article describes studies on the separation of uranium from acid pregnant leach solutions obtained Polish ores: dictyonema shales and sandstone rocks. Ion exchange chromatography was applied for sorption, using commercially available, strongly basic anion exchanger, Dowex 1. In model experiments, influence degree crosslinking 1 efficiency extraction investigated. effect H 2 SO 4 concentration breakthrough curve uranyl ions resins, different crosslinking: X4, X8 X10, examined....
Abstract The possibility of rare earth elements (REE) separation by ion interaction chromatography (IIC) employing their complexes with diglycolic acid (ODA) in anion exchange mode has been studied theoretically and experimentally. Calculations, assuming that only trivalent complex is significantly uptaken the stationary phase, indicated at pH 4–6, retention lanthanide series should increase from La to Tb–Dy–Ho region yttrium showing apparent atomic number (App.At.No.) 67½ then decrease...
Abstract Ion chromatographic separation of rare earth elements (REE) was studied using isocratic elution from Dionex Pac CS3 + CG3 column with sulfonic acid functional groups and buffered solutions tartaric (HTart), citric (HCit) nitrilotriacetic (NTA) acids, respectively, at temperatures 25–70°C. Apparent atomic numbers (App.At.No.) Y Sc respect to lanthanide series were established found vary widely both the ion exchange system temperature. A novel method for Dy-Y-Tb triad proposed 68 m...
Abstract Two new group separation schemes, based on ion exchange chromatography, for the selective and quantitative isolation of rare earth elements (REE) from accompanying elements, were devised. After checking their performance with aid radioactive tracers, schemes further used together ICP-MS, NAA chromatography determination Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb Lu in two certified reference materials (CRMs). The results compared another series analyses, where REEs...
New ion interaction chromatographic (IIC) method employing Kromasil 100 C18 column and tetra-n-butylammonium hydroxide (TBAOH) as an reagent (IIR) is able to separate yttrium from Rare Earth Elements (REE) anionic complexes with nitrilotriacetic acid (NTA). for the determination of Y in REE mixture was devised validated by analysis certified reference material (CRM). Potential possibilities new system larger scale applications including macro-micro events were demonstrated.
ABSTRACT Distribution coefficients of 23 elements between chelating resin Duolite ES 346 containing amidoximo groups and glycine - HCl buffer /pH = 2 3.5/, acetate 3.6 5.6/ solutions /0.05 12M/ respectively were measured by batch equilibration at tracer loadings. While alkali alkaline earth metals are practically not retained the resin, transition other metal ions show quite differentiated pattern selectivity. The exhibits amphoteric properties in certain conditions both cations anions can...
