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.
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.
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.
It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na 4 EDTA. 4H 2 O. The properties of solutions produced from the anhydrous and hydrated forms are the same, provided they are at the same pH. It is used as a source of the chelating agent EDTA 4-. A 1% aqueous solution has a pH of approximately 11.3.
Tetrasodium iminodisuccinate is a chelating agent, forming complexes of moderate stability (10 −16), which includes (as a pentadentate ligand) alkaline earth and polyvalent heavy metal ions with one molecule of water in an octahedral structure. [7] In 0.25% aqueous solution, a pH of 11.5 results for tetrasodium iminodisuccinate. The salt is ...
The core technique was the usage of a bridge-type heterogeneous chelation architecture to capture metal in a stable water-soluble state. Surprisingly, platinum ion in this particular multi-phase bridged chelated state is amazingly stable. Chelated platinum solution is in the form of high energy dielectric aqueous solution.

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]
