ETHYLENEDIAMINETETRAACETIC DIANHYDRIDE Usage And Synthesis

Uses

Ethylenediaminetetraacetic Acid Dianhydride (A-EDTA) is used as a reagent in the synthesis of a new class of polymer, poly-2.6-piperazinedione. A-EDTA is also used in the synthesis of EDTA functionalized polyacrylnitriles (PANs) by direct reaction with amine and hydroxyl functionalized polyacrylnitrile.

Application

(1) 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.
(2) 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.
(3) 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.

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.
