Fa'aaogā:
Fa'ato'aga fa'aoga: mea mata o le phosphate fertilizerand fafaga meaʻai
Alamanuia fa'aoga: vaila'au mata'utia
1. Puipui le uamea mai le pala
2. Fa'afefiloi ma le nitric acid e pei o vaila'au fa'alelei e fa'aleleia ai le pito i luga ole u'amea
3.Material o le phosphatide lea e faʻaaogaina mo le gaosiga o oloa fufulu ma iniseti
4.O le gaosiga o le phosphorus o loʻo i ai mea faʻafefe.
Fa'aoga mea'ai fa'aopoopo: fa'a'a'ai fa'ato'aga, Fa'afefete Nutri-ents, , e pei o le coca-cola.
Fa'aaogāga fa'afoma'i: e maua ai vaila'au o lo'o iai le phos-phorus, pei o le Na 2 Glycerophosphat
O le phosphoric acid e masani ona faʻaaogaina i vailaʻau, meaʻai, faʻalaʻau ma isi pisinisi, e aofia ai le puipuia o le ele, meaʻai faʻaopoopo, nifo ma taotoga faʻapitoa, EDIC caustics, electrolytes, flux, dispersants, caustics alamanuia, fertilizers e pei o mea mata ma vaega o le faamamaina o fale oloa. E faʻaaogaina foi e fai ma vailaʻau, phosphates o meaʻai mo mea ola uma.
Phosphoric acid poʻo le orthophosphoric acid, faʻatasi ai ma le mamafa mole o le 97.994, o se vailaʻau masani masani. Ose ga'o malosi feololo. E maua e ala i le faʻamavaeina o le phosphorus pentoxide i le vai vevela. O le Orthophosphoric acid e maua faʻapisinisi e ala ile togafitia ole apatite ile sulfuric acid. O le phosphoric acid e faʻamama faigofie ile ea. O le vevela e aveesea ai le vai i le pyrophosphoric acid, ma atili leiloa ai le vai ile metaphosphate.
Fa'amatalaga fa'aopoopo:
Talosaga fanua:
1. Faʻatoʻaga: Phosphoric acid o le mea mataʻutia mo le gaosiga o faʻamaʻi phosphate taua (superphosphate, potassium dihydrogen phosphate, ma isi), faʻapea foʻi ma mea mataʻutia mo le gaosiga o meaʻai (calcium dihydrogen phosphate).
2. Alamanuia: Phosphoric acid o se vailaʻau mataʻutia taua. O ana galuega tauave autu e faapea:
(1) Ia togafitia le uʻamea ma faʻatupuina se ata phosphate e le mafai ona faʻaaogaina i luga o le uʻamea e puipuia ai le uamea mai le pala.
(2) Fa'afefiloi ma le nitric acid e avea o se vaila'au kemisi e fa'aleleia atili ai le fa'au'uga o le u'amea.
(3) Le gaosiga o vailaau fa'amasani, vailaau fa'ala'ala'au mea mata phosphate ester.
(4) Mea mata'utia mo le gaosiga o le phosphorus e fa'agata mu.
3, meaʻai: phosphoric acid o se tasi o meaʻai faaopoopo, i meaʻai e pei o se sui oona, fefete meaʻai sui, cola o loʻo i ai le phosphoric acid. Phosphates o ni mea'ai fa'aopoopo taua ma e mafai ona fa'aaogaina e fa'aleleia ai mea'ai.
4, vailaʻau: phosphoric acid e mafai ona faʻaaogaina e fai ai vailaʻau o loʻo iai phosphate, e pei o le sodium glycerophosphate, ma isi.
