The purpose of this study was to prepare a dense HApGEL nanocomposite through a free ion production process. Methods Free ionic calcium, Ca2, was produced through electrodialysis process using a cation membrane CMV. Triprotic acid ions were diffused through an anion membrane AMV from an aqueous solution of H3PO4.
A process for producing a calcium phosphate comprising the steps of a dissolving at least one member selected from the group consisting of calcium hydroxide and calcium oxide in water with at least one member selected from the group consisting of a sugar, a sugar alcohol, and a polyhydric alcohol b and adding phosphoric acid to the solution obtained to precipitate a calcium phosphate.
Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium Ra-226 and strontium in the gastrointestinal GI tract.
Jan 19, 2018 Calcium and phosphate are critical to human physiology e.g. neuromuscular function and are also needed for skeletal mineralization. An understanding of calcium and phosphate metabolism is required for the clinician to evaluate disorders of the levels of calcium and phosphorus as well as metabolic skeletal disorders. In this chapter, we review calcium and phosphate homeostasis
Apr 01, 1994 A new process for the production of defluorinated dicalcium phosphate using phosphate rock was developed. This new process has the main characteristic of being clean, without the production of any liquid waste. The process has essentially three main steps phosphate rock digestion, defluorination and neutralization.
