Tripotassium phosphate K3PO4 CAS 7778-53-2 vasega mea'ai
Fa'amatalaga o le Oloa
O le Potassium phosphate o se vailaʻau e maualuga lona gafatia e faʻamamā ai, e avea o se sui e faʻatonutonu ai le pH, e masani ona faʻaaogaina o se vaega mo le tele o ituaiga o ala o faasalalauga e faʻaaogaina i le totoina o meaola ninii, o se vaega i le phosphate buffered saline (PBS). E maua i le tele o foliga: monobasic, dibasic, ma tribasic (K3PO4). O le tele o pH neutral potassium phosphate buffer solutions e aofia ai faʻafefiloi o foliga monobasic ma dibasic i tikeri eseese, e fuafua i le pH e manaʻomia. O Gomori buffers, o le phosphate buffers e masani ona faʻaaogaina, e aofia ai se faʻafefiloi o le monobasic dihydrogen phosphate ma le dibasic monohydrogen phosphate. E ala i le fesuiaʻi o le aofaʻi o masima taʻitasi, e mafai ona saunia se vaega o buffers e faʻamamā lelei i le va o le pH 5.8 ma le pH 8.0 (faʻamolemole tagaʻi i laulau o loʻo i lalo). O Phosphates e matua maualuga lava le gafatia e faʻamamā ai ma e faigofie ona solu i le vai.

Talosaga
1) O le Potassium phosphate o se mea e fa'atonutonu ai le 'a'asa ma le mea e fa'a'a'a ai le 'aisa (e fa'aaogaina e fusifusia ai ions u'amea). E taofia ai le mago ma e fa'aaogaina o se mea e fa'amautu ai le 'a'asa i pauta fa'apea fo'i ma le puipuia o le fa'aputuina o ni fa'aputuga. E fa'ateleina ai le gaioiga o antioxidants.
2) I le alamanuia o meaʻai (Meaʻai faʻaopoopo), e faʻaaogaina o se emulsifier, potassium fortifier, mea manogi, mea e fusi ai aano o manu. E fesoasoani le potassium phosphate e faʻamautu, faʻamaʻaʻa ma faʻatonutonu le acidity ma le susu i meaʻai. E tusa ai ma le aiaiga a le FAO (1984), o lona faʻaaogaina ma le aofaʻi faʻatapulaʻaina e pei ona taua i lalo: supo vave; masima phosphate atoa: 1000 mg/kg (fuafuaina e faʻavae i luga o le P2O5); vae puaa vela, ham, aano o manufasi vela 3g/kg (aofaʻi e faʻaaoga tasi pe aofaʻi tuʻufaʻatasi ma isi phosphate, fuafuaina i luga o le P2O5); susu pauta maualalo le malosi, susu faʻaputu, kulimi faʻavaivaia: 2 g/kg (aofaʻi e faʻaaoga tasi); aofaʻi tuʻufaʻatasi ma isi mea e faʻamautu ai: 3 (fuafuaina i luga o le mea e leai se vai); susu pauta, sisi faʻagasolo: 5g/kg; sisi faʻagasolo, le aofaʻi atoa o le phosphate 9g/kg (fuafuaina o le phosphorus); meainu malulu: 2g/kg (aofaʻi e faʻaaoga tasi pe aofaʻi tuʻufaʻatasi ma isi phosphate, fuafuaina i luga o le P2O5).
3) E mafai ona fa'aaogaina mo le sauniaina o oloa pasta i le vai alkaline. E mafai ona fa'aaogaina mo le gaosia o fasimoli vai, pepa lelei, penisini fa'amamaina, pepa lelei, o le phosphorus ma le potassium fertilizers. E mafai ona fa'aaogaina o se fa'amalūlūina o le vai fa'apuna. E fa'aaogaina fo'i i vaila'au. O nisi taimi e fa'aaogaina ai le Potassium phosphate o se vaila'au. E mafai ona i ai sona aafiaga diuretic ma galue o se laxative pe a fa'aaogaina i le tele o vaila'au. Peita'i, e mafai e le phosphorus ona fegalegaleai ma nisi vaila'au, e aofia ai corticosteroids ma potassium-sparing diuretics, e fa'ateleina ai le lamatiaga o a'afiaga leaga; fa'aaoga pe a fautuaina e se foma'i e fai.
4) E mafai ona faʻaaogaina e fai ma vailaʻau faʻataʻitaʻi, mea e faʻamama ai ma mea e faʻamalūlū ai.
