ABSTRACTEthylenediaminetetraacetic acid (EDTA) is a chelating agent can bind to metals via four carboxylate and two amine groups. It is a polyamino carboxylic acid and a colorless, water-soluble solid, which is widely used to dissolve lime scale. It is produced as several salts, notably disodium EDTA and calcium disodium EDTA. EDTA reacts with the calcium ions in dentine and forms soluble calcium chelates. A review of the literature and a discussion of the different indications and considerations for its usage are presented.

Edetate disodium (EDTA) is a chelating (KEE-late-ing) agent. A chelating agent is capable of removing a heavy metal, such as lead or mercury, from the blood. Ethylenediaminetetraacetic acid (EDTA) is a chelating agent can bind to metals via four carboxylate and two amine groups. It is a polyamino carboxylic acid and a colorless, water-soluble solid, which is widely used to dissolve lime scale. It is produced as several salts, notably disodium EDTA and calcium disodium EDTA. EDTA reacts with the calcium ions in dentine and forms soluble calcium chelates. A review on EDTA’s known and unknown facts are presented in this article.

The potential of using hydrogels encapsulated with a water-soluble calcium salt, Ca(NO3)2 for the remediation and management of sodic soil, a degenerate soil condition associated with irrigation of recycled water was investigated. Environmentally friendly hydrogel, poly(2-hydroxyethyl methacrylate) (PHEMA) was synthesised from the monomer, 2-hydroxyethyl methacrylate (HEMA). HEMA was also used to copolymerise with another monomer, N-vinyl pyrrolidinone (NVP) to form a more hydrophlic hydrogel. Starch and glucose were incorporated in certain hydrogels with the intention of evaluating their biodegradability in soils since starch and glucose would serve as nutrients for microbials in soils. Delivery of calcium ions embedded in hydrogels were investigated on sodic and non-sodic clay loam under saturated condition. It was found that the optimum hydrogel for this application was the copolymer that contained HEMA and NVP in equal mole ratio.

Fisetin is a natural antioxidant with a wide range of nutraceutical properties, including antidiabetic, neuroprotecting, and suppression or prevention of tumors. The present work describes the preparation of a water-soluble, solid inclusion compound of fisetin with gamma-cyclodextrin (γ-CD), a cyclic oligosaccharide approved for human consumption. A detailed physicochemical analysis of the product is carried out using elemental analysis, powder X-ray diffraction (PXRD), Raman, infrared and 13C{1H} CP-MAS NMR spectroscopies, and thermal analysis (TGA) to verify fisetin inclusion and to present a hypothetical structural arrangement for the host–guest units. The antioxidant activity of the γ-CD·fisetin inclusion compound is evaluated by the DPPH assay.
