EDTA is an important ligand used in many industrial products as well as in agriculture, where it is employed to assist in phytoextraction procedures and the absorption of nutrients by plants. Due to its intensive use and recalcitrance, it is now considered an emerging pollutant in water, so there is great interest in techniques suitable for its monitoring. This work proposes a method based on formation of the Mn(III)-EDTA complex after oxidation of the Mn(II)-EDTA complex by PbO2 immobilized on cyanoacrylate spheres. A design of experiments (DOE) based on the Doehlert matrix was used to determine the optimum conditions of the method, and the influence of the variables was evaluated using a multiple linear regression (MLR) model. The optimized method presented a linear response in the range from 0.77 to 100.0μmolL(-1), with analytical sensitivity of 7.7×10(3)Lmol(-1), a coefficient of determination of 0.999, and a limit of detection of 0.23μmolL(-1). The method was applied using samples fortified at different concentration levels, and the recoveries achieved were between 97.0 and 104.9%.

“…Researchers have related red CL emission from permanganate reactions to the relaxation of the Mn(II) 4 T1 excited state to the 6 A1 ground state. 25,26 They proved the mechanism of CL generation by KMnO4 as below: the oxidation of a substrate by Mn(VII) generates Mn(III), which then produces the Mn(II)* excited state (emission at about 700 nm).…”

“…In soft drinks containing ascorbic acid and sodium benzoate, EDTA mitigates the formation of benzene (a carcinogen). 4 It is also added to pharmaceuticals to enhance the action of preservatives and antibacterials and to stabilize the action of antioxidants. 3,5 These properties are due to its ability to chelate metal ions, which decrease their reactivity and prevent them to catalyze oxidation reactions, as well as to inactivate enzymes that require di-or trivalent cations for activity.…”

A sensitive and selective chemiluminescence method was developed to determine ethylenediaminetetraacetic acid (EDTA) in water samples. It was observed that gold nanoparticles (AuNPs) catalyzed chemiluminescence (CL) reactions of permanganate-aldehydes which underwent an enhancement effect in the presence of iron(III) ions (Fe 3+ ). This effect is more remarkable in the presence of EDTA, and a highly intensive CL emission is created in proportion to the EDTA concentration. These observations form the basis of the method for the high sensitive determination of EDTA in the 0.83 -167 nmol L -1 concentration range, with a detection limit of 0.25 nmol L -1 . The relative standard deviations for five repeated measurements of 5, 40 and 140 nmol L -1 EDTA were 1.14, 2.48 and 0.65%, respectively. The method has good selectivity toward EDTA, and there are no interferences from other ions. The offered method has good precision, and was satisfactorily used for the sensitive determination of EDTA in water samples.

“…The LODs may be improved with enrichment techniques [5,17], but this increases the effort for sample preparation too. The formation of Fe(III) EDTA complexes is also used for the extraction of EDTA from difficult matrices and the subsequent determination by liquid chromatography (LC) [18,19].…”
