Chelation is useful in applications such as providing nutritional supplements, in chelation therapy to remove toxic metals from the body, as contrast agents in MRI scanning, in manufacturing using homogeneous catalysts, in chemical water treatment to assist in the removal of metals, and in fertilizers.
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.

When PSB is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. [citation needed] The use of PSB as inoculants increases P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg P 2 O 5 /ha or 50 percent of the need for phosphatic fertilizers ...
Doctors explain what chelation therapy is, what it treats, health benefits, and risks involved. Here's what to know about chelation therapy.
The formation of Fe(III)-EDTA (FeY) − can be described as follows: FeSO 4 ∙7H 2 O + K 2 H 2 Y + 1/4 O 2 → K[FeY(H 2 O)]. H 2 O + KHSO 4 + 5.5 H 2 O (1) [8]. Iron chelate has also been used as a bait in the chemical control of slugs, snails and slaters in agriculture in Australia and New Zealand.
The US CDC does not recommend chelation therapy, [25] in part because chelation may accentuate kidney damage. [24] For long-term exposure, considerable evidence indicates that the traditional chelator EDTA can reduce a body's overall cadmium load. Co-administered antioxidants, including nephroprotective glutathione, appear to improve efficacy.
