Shandisa:
Kushandisa zvekurima: mbishi zvinhu zvephosphate fetiraiza uye kudya kunovaka muviri
Indasitiri kushandiswa: makemikari mbishi zvinhu
1.Chengetedza simbi kubva pakuora
2. Yakasanganiswa ne nitric asidhi semakemikari polishing agent kuti ivandudze kupera kwesimbi
3.Material ye phosphatide iyo inoshandiswa kugadzira chigadzirwa chekugeza uye chezvipembenene
4.Kugadzirwa kwe phosphorus ine flameretardant zvinhu.
Zvekuwedzera zvekudya zvinoshandisa: acidic flavour, Yeast Nutri-ents, senge coca-cola.
Kushandiswa kwekurapa: kugadzira mushonga une phos-phorus, senge Na 2 Glycerophosphat

tyiuyituy Zvichitevera kuwanikwa kwephosphorus neGerman chemist Kunda kugadzira phosphorus, British chemist Bo Yili akagadzirawo phosphorus akazvimiririra. Akanga ariwo kemisiti wekutanga akadzidza phosphorus nemakomponi. The thesis "Kuedza Kutsva kweCold Light Observed" yakanyora "Phosphorus inogadzira utsi huchena mushure mekupisa, uye mhinduro inogadzirwa mushure mekuita kwechiutsi chichena nemvura ine acidic." ), Uye mhinduro inogadzirwa nemvura ndeye phosphate, asi haana kuwedzera kudzidza phosphate.

Chemist wekutanga akadzidza phosphate aive wechiFrench chemist Lawar. Muna 1772, akaita chiyedzo chakadaro: Isa phosphorous muchivharo che mercury-chakavharwa bhero kuti upise. Migumisiro yekuedza inogumiswa kuti imwe phosphorus inogona kupiswa mumhepo yehuwandu; chena hupfu zvidimbu zvemvura-isina phosphorus inogadzirwa kana phosphorus inopisa, sechando chakanaka; 80%; iyo phosphorus inenge 2.5 nguva isati yatsva; iyo chena poda inonyungudika mumvura kuti iite phosphate. Lavis inoratidzawo kuti phosphate inogona kugadzirwa neconcentrated nitric acid uye phosphorus.

Mushure memakore anopfuura zana, nyanzvi yekemesitiri yekuGermany Libii akaita ongororo dzakawanda dzemakemikari ekurima kuti aburitse kukosha kwephosphorus nephosphate pahupenyu hwezvirimwa. Muna 1840, Li Bixi's "Basa reorganic chemistry mukurima uye physiology" yakaratidza nesainzi dambudziko rekubereka kwevhu uye yakaratidza basa re phosphorus pazvirimwa. Panguva imwecheteyo, akawedzera kuongorora kushandiswa kwephosphate uye phosphate sefetiraiza, uye kugadzirwa kwephosphate kwakapinda munguva yakakura.
