Compared to straight fluorides, sodium monofluorophosphate has slightly less aftertaste. SMFP is also used in some medications for the treatment of osteoporosis. [2] In 1991, sodium monofluorophosphate was found by Calgon to inhibit the dissolution of lead in drinking water when used in concentrations between 0.1 mg/L and 500 mg/L. [4]
Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The production of fertilizer is the largest source responsible for minerals mined for their phosphate content.
Fluorapatite as a naturally occurring impurity in apatite generates hydrogen fluoride as a byproduct during the production of phosphoric acid, as apatite is digested by sulfuric acid. The hydrogen fluoride byproduct is now one of the industrial sources of hydrofluoric acid , which in turn is used as a starting reagent for synthesis of a range ...
Similarly, toothpaste typically contains a source of fluoride anions (e.g. sodium fluoride, sodium monofluorophosphate). Too much fluoride results in dental fluorosis and/or skeletal fluorosis. [15] Fission tracks in apatite are commonly used to determine the thermal histories of orogenic belts and of sediments in sedimentary basins. [16]
Story of our lives: We have a hankering for sesame chicken from our favorite Chinese takeout spot, then we can’t stop eating and wake up puffy and bloated from the sodium, sugar and deep-fried ...
Monofluorophosphate is an anion with the formula PO 3 F 2−, which is a phosphate group with one oxygen atom substituted with a fluoride atom.The charge of the ion is −2. The ion resembles sulfate in size, shape and charge, and can thus form compounds with the same structure as sulfate
The International Benchmarking Network for Water and Sanitation Utilities estimated the non-revenue water for a sample of Chinese water utilities at 27% in 2006 and 21% in 2001. [50] One explanation for the relatively low level of NRW may be that most Chinese live in dense apartment complexes, which results in compact distribution systems.
In Chinese, characters for the elements are the last officially created and recognized characters in the Chinese writing system.Unlike characters for unofficial varieties of Chinese (e.g., written Cantonese) or other now-defunct ad hoc characters (e.g., those by the Empress Wu), the names for the elements are official, consistent, and taught (with Mandarin pronunciation) to every Chinese and ...
