Speciation analysis of tellurium by solid-phase extraction in the presence of ammonium pyrrolidine dithiocarbamate and inductively coupled plasma mass spectrometry

Abstract: Under acidic conditions tellurium(IV) formed a complex with ammonium pyrrolidine dithiocarbamate (APDC). The tellurium(IV) complex was completely retained on a non-polar Isolute silica-based octadecyl (C(18)) sorbent-containing solid-phase extraction (SPE) cartridge, while the uncomplexed Te(VI) passed through the cartridge and remained as a free species in the solution. Only partial Te(IV) was retained on the SPE cartridge for samples without addition of APDC. On the basis of different retention behaviours of… Show more

“…the literature for speciation of tellurium is shown in Table 4. As could be seen, the LODs of this method are much lower than those obtained by SPE-HG-AAS [32], SPE-ICP-MS [12], SPE-ICP-AFS [9], LLE-AAS [1], CE-UV [33], and HPLC-ICP-MS [4].…”

“…However, the method could not exactly detect the Te(IV) in seawater due to the deficient LOD. Yu et al [12] described a procedure for the speciation of Te(IV, VI) by SPE-ICP-MS. Te(IV) complex with APDC was completely retained on a nonpolar silica-based octadecyl (C18) sorbent-containing SPE cartridge, while the uncomplexed Te(VI) passed through the cartridge and remained as a free species in the solution prior to its determination by ICP-MS. The total Te concentration was also obtained by ICP-MS.…”

“…Several instrumental techniques have been applied for the determination of inorganic tellurium speciation. These include inductively coupled plasma-mass spectrometry (ICP-MS) [6,7], inductively coupled plasma atomic emission spectrometry (ICP-AES) [8], electrothermal atomic absorption spectrometry (ETAAS) [3,[9][10][11][12], hydride generation atomic absorption spectrometry (HG-AAS) [13,14], hydride generation atomic fluorescence spectrometry (HG-AFS) [15][16][17][18], gas chromatography-mass spectrometry (GC-MS) [19], cathodic stripping voltammetry [20], capillary electrophoresis with UV detection (CE-UV) [21], capillary electrophoresis coupled with ICP-MS detection (CE-ICP-MS) [22] and anion exchange HPLC-ICP-MS [23,24]. Low concentration and matrix interference are two problems in detecting tellurium compounds.…”

Such techniques as atomic emission spectrometry (AES) with inductively coupled (ICP) or microwave (MP) plasma, in conjunction with mass spectrometry, [30][31][32][33], atomic fluorescence spectrometry, [34][35][36], the optical emission spectrometry [37] are used for the tellurium and tellurium trace analysis in various objects.…”
