Description

Application

• Photo-Fenton oxidation of cylindrospermopsin at neutral pH with LEDs.: This study investigates the use of photo-Fenton processes catalyzed by Ethylenedinitrilotetraacetic acid (EDTA) under neutral pH conditions, optimizing reaction parameters for environmental applications (Ortiz et al., 2023).


• Mixtures of chelating agents to enhance photo-Fenton process at natural pH: Influence of wastewater matrix on micropollutant removal and bacterial inactivation.: Research shows how EDTA, when used in combination with other chelators, enhances the efficiency of the photo-Fenton process at natural pH levels for water treatment, focusing on micropollutant degradation and pathogen inactivation (López-Vinent et al., 2021).


• A new route to "bifunctional" chelating agents: conversion of amino acids to analogs of ethylenedinitrilotetraacetic acid.: Describes a synthetic method to transform standard amino acids into bifunctional analogs of EDTA, expanding the utility of these chelators in biochemical and industrial applications (Yeh et al., 1979).
