Dissolution and chelation of metal elements [ edit ] Organic acids have the ability to dissolve soil minerals , and can destroy silicate minerals and iron and aluminum oxides , [ 8 ] so that metal ions are precipitated and complexed with organic complexing agents through ion exchange, surface absorption, and chelation-reaction mechanisms. [ 9 ]
A chelating agent is the main component of some rust removal formulations. Citric acid is used to soften water in soaps and laundry detergents. A common synthetic chelator is EDTA. Phosphonates are also well-known chelating agents. Chelators are used in water treatment programs and specifically in steam engineering.
Aside from EDTA, the chelating agent EDDHA is used to solubilize iron in water. It also can be used for the purposes of agriculture as it is bioavailable to plants. [10] In iron chelation therapy, deferoxamine, has been used to treat excess iron stores, i.e. haemochromatosis. [11]

This white, water-soluble powder has a wide range of applications across industries. Originally derived from gluconic acid in the 19th century, Sodium Gluconate is known for its chelating properties and is utilized as a chelating agent in various processes. It finds applications in textile, metal surface treatment, cement, and more.
EDDHA or ethylenediamine-N,N ′-bis(2-hydroxyphenylacetic acid) is a chelating agent. Like EDTA, it binds metal ions as a hexadentate ligand, using two amines, two phenolate centers, and two carboxylates as the six binding sites. The complexes are typically anionic. The ligand itself is a white, water-soluble powder.
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
DOTA is derived from the macrocycle known as cyclen.The four secondary amine groups are modified by replacement of the N-H centers with N-CH 2 CO 2 H groups. The resulting aminopolycarboxylic acid, upon ionization of the carboxylic acid groups, is a high affinity chelating agent for di- and trivalent cations.
