Abstract: Classical chelating agents (especially aminopolycarboxylates, APCs and phosphonates) are till date the commonly used in industrial and home processes. This is due to their ability to strongly bind metals, and perhaps their being available in the market over a long time now. Abundant evidences proved that they are not environmentally benign. This has spurred the quest of industrialists and academia, as prompted by environmental policies, towards low toxicological profile and environmentally friendly chelating agents. The desire has resulted into annual rise in formulations and proposals of Greener alternative chelators such as glutamic diacetic acid (L-GLDA), ethylenediamine disuccinic acid [S, S]- EDDS, polyaspartic acid, citrate, gluconic acid, amino acids, lipophilic β-diketone (14,16)-hentriacontanedione, plant extracts etc. to be used in place of the classical chelating agents. For reasons of environmental compatibility, low toxic profile and sustainability, these Greener alternative chelants are better employed for industrial uses (such as metals extraction and recovery etc.) and home applications.
