✦ Synopsis

At concentrations above 1 ppm NTA can react with sparingly soluble compounds to release the metal and associated anions through complexation. It also interacts with sediment to release certain metals depending on the abundance of the metals in the sediment. In situ and laboratory experiments have been carried out to study such interactions and also to follow the fate of these released metals after NTA has degraded. Degradation of certain NTA-metal complexes in lake water medium has also been studied. It was found that certain NTA complexes (Cu, Ni, Cd, Hg) are very resistent to degradation.
