Capillary electrophoresis (CE) can very efficiently resolve different dissolved metal ion species as long as rates of ligand exchange are slow relative to time scales required for electromigration. Here, we detail the separation of several Cr(III) and Co(III) complexes with the multidentate chelating agents iminodiacetic acid, nitrilotriacetic acid, trans-1,2-cyclohexanediaminetetracetic acid, N-(2-hydroxyethyl)ethylenediaminetriacetic acid, trimethylenediaminetetraacetic acid, and… Expand
Running buffers for determination of chromium(VI)/(III), cobalt(II) and zinc(II) in complex matrices by capillary electrophoresis with contactless conductivity detection.
TLDR
Complex matrices and rather high acidity in environmental samples are often the impelling challenges for the used running buffers of capillary electrophoresis, and the malic acid systems including MA-His, MA-Arg and MA-Tris were selected as the candidates with powerful separation efficiency and good response sensitivity.

Carboxylate-containing chelating agent interactions with amorphous chromium hydroxide : Adsorption and dissolution
Abstract Anthropogenic chelating agents and biological chelating agents produced by indigenous organisms may dissolve Cr III (hydr)oxides in soils and sediments. The resulting dissolved Cr IIIExpand
Capillary electrophoresis study of iron(II) and iron(III) polyaminocarboxylate complex speciation
Environmental context Methods for determining iron species are integral to investigations of iron cycling processes in the environment. Capillary electrophoresis is an effective tool for determiningExpand
Rates of nickel(II) capture from complexes with NTA, EDDA, and related tetradentate chelating agents by the hexadentate chelating agents EDTA and CDTA: Evidence of a “semijunctive” ligand exchange pathway
Abstract Many siderophores and metallophores produced by soil organisms, as well as anthropogenic chelating agent soil amendments, rely upon amine and carboxylate Lewis base groups for metal ionExpand
A technique for the speciation analysis of metal-chelator complexes in aqueous matrices using ultra-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry.
TLDR
A rapid and sensitive technique for the speciation analysis of complexes of five metal ions with two aminopolycarboxylate chelator variants, namely, EDTA and EDDS, including the simultaneous quantification of those complexes, is reported. Expand
Determination of Pb(II), Cu(II) and Fe(III) with capillary electrophoresis using ethylenediaminetetraacetic acid as a complexing agent and vancomycin as a complex selector.
TLDR
The simultaneous determination of metal ions using ethylenediaminetetraacetic acid (EDTA), Pb(II), Cu(II) and Fe(III) in tap water were successfully determined, and the recoveries were 99 - 105%. Expand
Oxidation of CrIII aminocarboxylate complexes by hydrous manganese oxide: products and time course behaviour
Environmental context Oxidation of CrIII (trivalent chromium) to CrVI (hexavalent chromium) is of environmental concern because CrVI is a known mutagen and carcinogen. Our results show that hydrousExpand
Capillary electrophoresis facilitates determination of metal complex stoichiometry by Job's method of continuous variation
Environmental context Knowledge of metal-chelating agent speciation is integral to our ability to predict and interpret the behaviour of synthetic chelating agents in the environment. CapillaryExpand
Speciation Analysis of Chromium by Adsorptive Stripping Voltammetry in Tap and River Water Samples
An adsorptive stripping voltammetric method for speciation analysis of chromium in natural water samples has been developed. Ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaaceticExpand
Confirmation of iron complex formation using electrospray ionization mass spectrometry (ESI-MS) and sample stacking for analysis of iron polycarboxylate speciation by capillary electrophoresis
Abstract The use of capillary electrophoresis (CE) and UV detection for the determination of metal speciation is based on the standards via matching migration time. Consequently, it requires that theExpand
