Abstract The waste stream of obsolete electronic equipment grows exponentially, creating a worldwide pollution and resource problem. Electrical (e-waste) comprises heterogeneous mix glass, plastics (including flame retardants other additives), metals rare Earth elements), metalloids. e-waste issue is complex multi-faceted. In examining the different aspects e-waste, informal recycling in developing countries has been identified as primary concern, due to widespread illegal shipments; weak...
It is demonstrated that similar methodologies are applicable to the exposure assessment of inorganic and organic pollutants in contaminated native soils/sediments different type origin. A special emphasis given correlation between results chemical extraction/fractionation data on biouptake trace metals, metalloids, hazardous compounds by plants soil organisms. Application extraction techniques potentially biodegradable fractions also discussed evaluated. Recent developments dynamic methods,...
Abstract Recommendations are given concerning the terminology of methods separation in analytical chemistry, including chromatography, electromigration techniques, and field-flow fractionation related techniques.
A new approach to performing an accelerated sequential extraction of trace elements from solid samples has been proposed. It shown that rotating coiled columns (RCC) earlier used in counter-current chromatography can be successfully applied the dynamic leaching heavy metals soils and sediments. sample was retained column as stationary phase under action centrifugal forces while different eluents (aqueous solutions complexing reagents, mineral salts acids) were continuously pumped through....
Abstract The investigation of environmental nano- and submicron particles is needed for the assessment their impact on environment human health as well understanding various natural anthropogenic processes. Nano- have an increased mobility, may serve a “carrier” toxic nutrient substances, hence are particular interest. So far, there lack knowledge about source, behavior, fate, toxicity particles. This article focused separation characterization methods, which currently used investigation....
Environmental contextThe role of rare earth elements in soil–plant systems remains unclear. We use continuous-flow extraction, designed to mimic natural conditions while minimising artefacts, study vitro chemical fractionation soil. The reveals a predominant association and metal-organic complexes independent soil type contamination, thereby provides valuable insights into the behaviour these systems. AbstractThe (REEs) has attracted increasing attention but still somewhat Along invivo...
A flow-through hyphenated analytical method has been tested that enables not only the accelerated and efficient fractionation of trace elements (TE) species in environmental solids to be achieved but allows real-time studies on leaching process made. Rotating coiled columns (RCC), earlier used mainly countercurrent chromatography, have successfully applied dynamic heavy metals soil, sediment, sludge samples. ground solid sample (about 0.5 g) was retained a PTFE rotating column as stationary...
The applicability of the three-step BCR leaching scheme to continuous-flow fractionation trace metals (TM) using rotating coiled columns (RCC) has been investigated taking soil and sediment reference samples (SRM-2710, CRM-601, BCR-701) as examples. A particulate sample was retained in column stationary phase under action centrifugal forces while different eluents, used according original optimised protocols, were continuously pumped through. whole procedure required 3-4 h instead at least...
