General description
Ethylenediaminetetraacetic dianhydride (EDTAD) is a ramification of ethylenediaminetetraacetate (EDTA), which consists of two anhydride groups that can react with the hydroxyl and the amino groups. It is a biodegradable compound that is used as a chelating agent.
Application
- Electrospun cellulose acetate/activated carbon composite modified by EDTA: This study explores the application of ethylenediaminetetraacetic acid dianhydride in creating efficient dye removal systems from water. The modification led to significant improvements in adsorption properties (Elmaghraby et al., 2023).
- Application of a new chitosan derivative for adsorption of copper (II) and oxyanions of chromium (VI): This research describes the use of ethylenediaminetetraacetic dianhydride as a modifier in creating bioadsorbents from chitosan, targeting heavy metal and dye removal from wastewater (Lucena de Sousa et al., 2024).
- Lignocellulosic biomass functionalized with EDTA dianhydride for removing Cu (II) and dye from wastewater: This article discusses the modification of Gundelia Tournefortii with ethylenediaminetetraacetic dianhydride to enhance its capabilities for copper and dye adsorption in wastewater treatment processes (Safardastgerdi et al., 2023).
