Influence of digestion procedures on the determination of rare earth elements in peat and plant samples by USN-ICP-MS
Analytical procedures for the determination of rare earth elements (REE) in 250 mg aliquots of difficult-todigest peat and plant matrices by ICP-MS were developed. Three different pressurised digestion approaches were tested for this purpose, namely (i) closed vessel acid digestion on a hot-plate at 180 uC, (ii) digestion in a microwave high pressure autoclave at a temperature of 240 uC and (ii...
متن کاملRare Earth Elements Profile
Definitions and characteristics The rare earth elements (REE) (sometimes referred to as the rare earth metals) are a group of 17 chemically similar metallic elements, including the 15 lanthanides, scandium and yttrium. The lanthanides are elements spanning atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu) (Table 1). The lanthanides all occur in nature, although promethium, the rarest, only...
متن کاملOnline preconcentration ICP-MS analysis of rare earth elements in seawater
[1] The rare earth elements (REEs) with their systematically varying properties are powerful tracers of continental inputs, particle scavenging intensity and the oxidation state of seawater. However, their generally low ( pmol/kg) concentrations in seawater and fractionation potential during chemical treatment makes them difficult to measure. Here we report a technique using an automated precon...
