Determination of NTA and EDTA and Speciation of Their Metal Complexes in Aqueous Solution by Capillary Electrophoresis

Article Abstract:

The use of chelates is increasing in plant nutrient research and in enhancing plant metal uptake. The authors illustrate the use capillary electrophoresis as a method for detecting chelate in plants that is fast, reproducible, and free of the need for complex sample pretreatment.

Determination of metal-EDTA complexes in soil solution and plant xylem by ion chromatography-electrospray mass spectrometry

Article Abstract:

Ethylenediaminetetraacetic acid (EDTA) in plant xylem exudate and soil solution is measured using an ion chromatography-electrospray mass spectrometry (IC-MS) method. MS chromatogram results for the samples are graphed and the role of chelators is discussed in depth.

Determination of EDTA, NTA, and other amino carboxylic acids and their Co(II) and Co(III) complexes by capillary electrophoresis

Article Abstract:

Capillary electrophoresis (CE) is a usefool tool in separating and detecting free amino carboxylic acids such as the synthetic multidentate chelating agents, EDTA (ethylenediaminetetraacetic acid) and NTA (nitrilotriacetic acid), and their Co(II) and Co(III) complexes in a single run without prior pretreatment. Equilibrium calculations of the CE results obtained indicate that Co(III) are thermodynamically and kinetically more stable and easier to detect and separate than Co(II) complexes.
