Description générale

Ethylenediamine-N,N′-disuccinic acid trisodium salt (EDDS) is an aminopolycarboxylic acid (APCA), which is used as a complexing agent. It forms stable water-soluble complexes with metal ions. EDDS has a better chelating property than EDTA. It can also be used as a flushing agent due to its eco-friendly characteristics and high biodegradability.

Application

EDDS (chelating agent) along with natural montmorillonite (NM) can be used in the photochemical degradation process of 17β-estradiol (E2). EDDS-NM complex can also be employed as an efficient photocatalysis system for wastewater treatment. Cu and Zn ions in the contaminated agricultural soil can be removed using EDDS via Cu and Zn complex formation.
Ethylenediamine-N,N′-disuccinic acid trisodium salt solution has been used as a chelate to study its effect on Eucalyptus camaldulensis tree under controlled deficit irrigation (CDI) condition.

The toxicity of heavy metals commonly impacts the survival of crustacean and bivalve larvae in hatchery culture, and this has led to the widespread use of EDTA to decrease this toxicity. Since EDTA has a very poor biodegradability leading to
