Abstract Reversed-phase ion-pair liquid chromatography is often used to analyse traces of EDTA in natural water samples. Some perturbations due to the presence of major anions in samples, which can compete for ion pair formation with the Fe-EDTA complex used for the detection, have been observed but never estimated and quantified. A new operational method for determining EDTA in natural water samples is proposed by taking into account anion interactions. Qualitative and quantitative analyses of… Expand

Determination of EDTA in Dairy Wastewater and Adjacent Surface Water
An HPLC-UV analytical method was developed to determine ethylenediaminetetraacetic acid (EDTA) in dairy wastewater and surface water. The optimizing separation was achieved by reversed-phase ion-pairExpand
Determination of ethylenediaminetetraacetic acid in nuclear waste by high-performance liquid chromatography coupled with electrospray mass spectrometry.
This analytical method was successfully applied for EDTA quantification in two real effluents resulting from a nuclear liquid waste process and the limit of detection of this method was determined at 34×10(-9)mol L(-1). Expand
Determination of multiple chelator complexes in aqueous matrices using ultra-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry.
The determination of aminopolycarboxylate chelators in environmental samples has remained an analytical challenge due to the structural similarities of these species and their minute concentrationsExpand
Simultaneous determination of DTPA, EDTA, and NTA by UV–visible spectrometry and HPLC
The UV–Vis and HPLC methods were proved to be viable also for analyses of natural and pulp mill waters and to be highly comparable in the amount of analytes measured in the dishwashing detergents by the three techniques. Expand
Direct analysis of ethylenediaminetetraacetic acid (EDTA) on concrete by reactive-desorption electrospray ionization mass spectrometry.
The proof of principle that reactive DESI can be applied to concrete samples to detect EDTA has been demonstrated and its capacity for semi-quantitative determination and localization of EDTA under ambient conditions and with very little sample preparation, minimizing sample manipulations and solvent volumes has been shown.

A gradient separation procedure achieved on-column preconcentration and matrix removal for the interference-free detection of metal chelates down to low nanomolar concentration in samples from various fields of environmental research. Expand
Determination of ferric iron chelators by high-performance liquid chromatography using luminol chemiluminescence detection.
A high-performance liquid chromatography post-column method has been developed for the analysis of FICs using the luminol/H2O2 system for chemiluminescence (CL) detection and a size-exclusion column was the most suited in terms of column efficiency and CL detection efficiency. Expand
Study on the Large Volume Stacking Using the EOF Pump (LVSEP) for Analysis of EDTA by Capillary Electrophoresis
The widespread use of ethylenediaminetetraacetic acid (EDTA) has requested an urgent monitoring program regarding surface and drinking water. Analyzing EDTA at low-level concentrations such as µg l−1Expand
Large‐volume sample stacking for analysis of ethylenediaminetetraacetic acid by capillary electrophoresis
To the best of the authors' knowledge, this LVSEP method represents the highest sensitivity for EDTA analysis via CE, and several drinking water samples were tested by this novel method with satisfactory results. Expand
