General description

Ethylenediamine tetraacetate (EDTA) is a calcium ion chelator,[1] that has a low molecular mass of 292.24 Da.[2]

Application


  • Dual-Responsive Hydrogels for Mercury Ion Detection and Removal from Wastewater.: This study discusses the application of ethylenediaminetetraacetic acid disodium salt in the development of dual-responsive hydrogels, highlighting its effectiveness in detecting and removing mercury ions from wastewater (Diacon et al., 2024).

  • Photocatalytic Hydrogen Evolution Activity of Nitrogen/Fluorine-Codoped Rutile TiO(2).: The article explores the role of ethylenediaminetetraacetic acid disodium salt in enhancing the photocatalytic activity of nitrogen/fluorine-codoped rutile TiO(2) for hydrogen evolution (Miyoshi et al., 2023).

  • High-efficiency cleaning technology and lifespan prediction for the ceramic membrane treating secondary treated effluent.: This study presents a novel cleaning technology involving ethylenediaminetetraacetic acid disodium salt for ceramic membranes, offering insights into efficiency enhancements and lifespan predictions (Lv et al., 2023).

  • Reversible Morphology Locking via Metal Infiltration in a Block Copolymer.: This research investigates the reversible morphology locking of block copolymers facilitated by metal infiltration, using ethylenediaminetetraacetic acid disodium salt as a key component in the process (Ma et al., 2023).

Biochem/physiol Actions

Ethylenediaminetetraacetic acid disodium salt has the ability to block the binding of vasoactive intestinal peptide to macrophage membranes.[1] It is mainly used in the purification of protein, to remove divalent cations and also to prevent protease activity.[2]
