It is commonly used as a pigment in paints, as a reducing agent in metallurgy, and as a source of sulfur in the production of sulfuric acid. CALCIUM SULFIDE is also used in the manufacturing of fireworks and in the treatment of wastewater. It is important to handle this compound with ...
Moreover, based on the sequence of ionic detachment (first fluorine for FA or hydroxide for HA, followed by calcium and afterwards by orthophosphate) it is suggested that dissolution of apatites is always incongruent (non-stoichiometric) at the atomic (ionic) level. However, a lack of the ...
15.The method of claim 14, wherein the oxidizing agent is sodium hypochlorite, sodium hydroxide, hydrogen peroxide, or chlorine gas. 16.A method of depleting iron from a geothermal brine solution, said method comprising:(a) contacting the geothermal brine solution with an oxidizing agent, where...
Calcium sulfate is a hydrophilic substance that tends to release ionic components capable of altering intracellular enzyme activities [40]. Therefore, the LDH assay is an appropriate method to verify changes in cell membrane integrity, which is a vital mechanism of assessing cell viability/toxicity. ...
When calcium hydroxide is completely consumed, the dissolution of the C-S-H gel begins. The Ca/Si ratio affects the rate of C-S-H dissolution as well. In the most severe cases of acid attack, the dissolution of calcium–silicate–hydrate gel can seriously harm concrete's structural ...
