A microwave-assisted solvent-free synthesis of hydroxyapatite from calcium nitrate and sodium phosphate is reported. The product was characterized with respect to the presence of foreign ions and its thermal behavior. An apatite phase was formed in the mixture after irradiation with 2.45 GHz ...
Precipitation method:Commercial HA is often prepared by compacting and sintering apatite powder prepared by precipitation reaction betweencalcium nitrateand ammonium phosphate solution [38–41]. Our method uses calcium acetate instead of calcium nitrate or calcium chloride solution to avoid potential incorpor...

Nitrate and phosphate absorption-related genes were also detected in peanut kernels. The expression levels of three genes encoding NRT1/PTR family members changed, among them, two genes were up-regulated, and one gene was down-regulated under Ca2+ sufficient conditions compared to Ca2+ ...
showing the morphology of freshly precipitated CO2sorbents: (a) material precipitated using calcium acetate and ammonium carbonate (pH 9.7), (b) material precipitated using calcium acetate and sodium carbonate (pH 9.7), and (c) material precipitated using calcium nitrate and sodium carbonate (pH ...
identification test solubility insoluble in water; Soluble in dilute hydrochloric acid and dilute nitric acid. According to the OT-42 method. 1 ml of a solution of 1% sample of dilute hydrochloric acid test solution (TS-117) was added with several drops of silver nitrate test solution (TS-210...
Calcium nitrate is the most used precursor for the incorporation of calcium. However, this route requires calcination of the particles at high temperatures so that the calcium is incorporated, and the toxic nitrate byproducts are eliminated [5]. Greasley et al. [14] faced this problem when ...
Rubber wastewater has a high concentration of ammonia, nitrate, phosphorus, and suspended solids. The Lampang clay/HA composite completely removed total Kjehldahl nitrogen and total phosphorus, while the suspended solids removal was almost 98%, and the biochemical oxygen demand was reduced by 76%....
