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
Ose atina'e fa'asalalau fa'atasi ma le aoina o meatotino tau le atamai tuto'atasi, atina'e, gaosiga, fa'atau, tautua, fa'atau atu.
O le phosphoric acid ose acid inorganic masani, o le H3PO4. E le faigofie ona faʻafefe, e le faigofie ona malepe, ma e faigofie ona taʻape i le ea.Phosphateo se feololo-malosi, ma lona tulaga crystallization o le 21 ° C. A maualalo le vevela nai lo lenei vevela, o le crystallization o mea semi-vai o le a precipitated. O le fa'avevela o le a le maua ai le vai e maua ai sikoa phosphate, ona fa'amama atili ai lea o le vai e maua ai le polar acid phosphoric acid. Phosphoric acid e iai le malosi, ma o lona acidity e vaivai atu nai lo hydrochloric acid, sulfuric acid, nitric acid, ae sili atu le malosi nai lo le acetic acid ma le boric acid.
Vailaau: E mafai ona fa'aoga le phosphoric acid e fai ai vaila'au o lo'o iai phosphate, pei ole sodium glycerol phosphate. Fa'ato'aga: Phosphate o se mea taua tele mo le gaosia o le phosphate fertilizer (calcium phosphate, potassium dihydrogen phosphate, ma isi), ma o se mea mataʻutia foi mo le gaosia o meaʻai taumafa (calcium phosphate);
Mea'ai: phosphate o se tasi o mea'ai fa'aopoopo. E faʻaaogaina e avea o meaʻai ma meaʻai faʻafefete i meaʻai, ma o le Coca-Cola o loʻo i ai le phosphate. O le Phosphate foi o se meaʻai taua faʻaopoopo, lea e mafai ona faʻaaogaina e fai ma faʻaleleia meaʻai;
Alamanuia: phosphate o se vailaʻau mataʻutia taua, o le matafaioi autu e faapea;
1. Togafitiga o le u'amea ma fa'atupuina se ata phosphate refractory i luga o le u'amea e puipuia ai le uamea mai le pala;
2. Faʻafefiloi ma le nitric acid e avea o se vailaʻau faʻamalo e faʻateleina ai le lamolemole o le uʻamea;
3. O mea mata'utia phosphate mo le gaosiga o sapalai fufulu ma vailaau fa'asaina;
4. O mea mataʻutia mo le gaosiga o le phosphorus -o loʻo iai faʻamaʻi afi;
