Tripotassium phosphate K3PO4 CAS 7778-53-2 giredhi rechikafu
Tsananguro yeChigadzirwa
Potassium phosphate imushonga une simba guru rekuchengetedza, Inoshanda semushonga wekuchengetedza pH, Inowanzo shandiswa sechikamu chemhando dzakasiyana dzezvinhu zvinoshandiswa mukukudziridza tupukanana, sechikamu mu phosphate buffered saline (PBS). Inowanikwa mumhando dzakasiyana-siyana: monobasic, dibasic, uye tribasic (K3PO4). Mazhinji e pH ane pH isina simba anosanganisira musanganiswa we monobasic ne dibasic form kusvika padanho rakasiyana, zvichienderana ne pH inodiwa. Gomori buffers, phosphate buffers inowanzoshandiswa, ine musanganiswa we monobasic dihydrogen phosphate ne dibasic monohydrogen phosphate. Nekusiyanisa huwandu hwemunyu wega wega, mhando dzakasiyana dzemabuffers dzinogona kugadzirwa kuti dzichengetedze zvakanaka pakati pe pH 5.8 ne pH 8.0 (ndapota ona matafura ari pazasi). Maphosphates ane simba guru rekuchengetedza uye anonyungudika zvakanyanya mumvura.

Kushandiswa
1) Potassium phosphate inodzora acidity uye chelating agent (inoshandiswa kusunga ma ions esimbi). Inodzivirira kuoma uye inoshandiswa se acid stabiliser muupfu pamwe nekudzivirira kuumbwa kwema clumps. Inowedzera kushanda kwema antioxidants.
2) Muindasitiri yezvekudya (zvekuwedzera zvekudya), inoshandiswa se emulsifier, potassium fortifier, flavouring agent, meat binder. Potassium phosphate inobatsira kudzikamisa, kukora uye kudzora acidity uye hunyoro muzvikafu. Zvichienderana neFAO (1984), kushandiswa kwayo uye huwandu hwayo hwakaganhurirwa ndeinotevera: muto wekukurumidza; munyu wephosphate yese: 1000 mg/kg (yakaverengerwa zvichibva paP2O5); makumbo enyama yenguruve yakabikwa, ham, nyama yakabikwa yakagayiwa 3g/kg (huwandu hwekushandiswa kamwe chete kana huwandu hwemusanganiswa neimwe phosphate, yakaverengerwa paP2O5); mukaka weupfu hwakaderera, mukaka wakakanyiwa, kirimu yakasanganiswa: 2 g/kg (huwandu hwekushandiswa kamwe chete); huwandu hwemusanganiswa neimwe stabilizer: 3 (yakaverengerwa pane chinhu chisina mvura); mukaka weupfu, chizi chakagadziriswa: 5g/kg; chizi chakagadziriswa, huwandu hwese hwephosphate 9g/kg (yakaverengerwa sephosphorus); chinwiwa chinotonhora: 2g/kg (huwandu hwekushandiswa kamwe chete kana huwandu hwemusanganiswa neimwe phosphate, yakaverengerwa paP2O5).
3) Inogona kushandiswa kugadzira zvigadzirwa zvepasta nemvura ine alkaline. Inogona kushandiswa kugadzira sipo yemvura, bepa remhando yepamusoro, peturu yakacheneswa, bepa remhando yepamusoro, iri phosphorus ne potassium fertilizer. Inogona kushandiswa sechinonyorovesa mvura muboiler. Inoshandiswawo mukurapa. Potassium phosphate dzimwe nguva inoshandiswa semushonga. Inogona kuva nemhedzisiro yekudonha kwemvura uye kushanda semushonga wekurara kana ikashandiswa muhuwandu hwemishonga. Zvisinei, phosphorus inogona kusangana nemimwe mishonga, kusanganisira corticosteroids uye potassium-sparing diuretics, zvichiwedzera njodzi yemigumisiro yakaipa; ingoshandisa chete kana chiremba akakuudza kuti uite izvozvo.
4) Inogona kushandiswa se analytical reagent, buffer uye softener.
