Research and development progress of green and high-efficient heavy metal chelators

Abstract

Chelators play a significant role in dealing with heavy metals pollution. As environmental protection is being increasingly attached much importance to, there is an urgent need for green and high efficient heavy metal chelators. The present work briefly outlines the production and application of some chelators and their environmental risks and solutions. It provides a complete understanding of heavy metal chelators and possible prospects to reach the green and highly efficient goal.
