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
Ina ua maeʻa le mauaina o le phosphorus ma le Siamani chemist Conquer e gaosia le phosphorus, na tutoʻatasi foi e le kemisi Peretania Bo Yili le gaosia o le phosphorus. O ia foi o le tagata kemisi muamua na suʻesuʻeina le phosphorus ma mea faʻapipiʻi. O le suʻesuʻega "A New Experiment of the Cold Light Observed" na tusia ai "O le Phosphorus e maua ai le asu paʻepaʻe pe a uma ona mu, ma o le vaifofo e maua pe a uma le gaioiga o le asu paʻepaʻe ma le vai o le acidic." ), Ma o le fofo e gaosia i le vai o le phosphate, ae na te leʻi suʻesuʻeina atili le phosphate.
O le fomaʻi muamua na suʻesuʻeina le phosphate o le fomaʻi Farani o Lawar. I le 1772, na ia faia ai se faʻataʻitaʻiga faʻapea: Tuu le phosphorus i totonu o se faʻailoga logo faʻamaufaʻailoga e susunuina ai. O fa'ai'uga fa'ata'ita'iga ua fa'ai'uina e mafai ona mu se aofa'iga o le phosphorus i se ea o se malosi; pa'epa'e pa'epa'e fasi vai - leai se phosphorus e gaosia pe a mu le phosphorus, e pei o le kiona; 80%; o le phosphorus e tusa ma le 2.5 taimi aʻo leʻi susunuina; o le paʻepaʻe paʻepaʻe e faʻafefe i totonu o le vai e fai ai le phosphate. Ua faamaonia foi e Lavis e mafai ona faia le phosphate i le nitric acid ma le phosphorus.
Ina ua maeʻa le silia ma le 100 tausaga, ua faia e le fomaʻi Siamani Libii le tele o suʻesuʻega vailaʻau faʻatoʻaga e faʻaalia ai le taua o le phosphorus ma le phosphate i le ola o laau. I le 1840, o Li Bixi's "The role of organic chemistry in agriculture and physiology" faʻasaienisi faʻaalia le faʻafitauli o le fausiaina o le eleele ma faʻaalia ai le matafaioi o le phosphorus i luga o laau. I le taimi lava e tasi, na ia suʻesuʻeina atili le faʻaogaina o le phosphate ma le phosphate e fai ma faʻalaʻau, ma o le gaosiga o le phosphate ua ulufale atu i se vaitau tele.
