Wehewehe Huahana
ʻO ka potassium phosphate kahi reagent me ka mana buffering kiʻekiʻe, lawelawe ia ma ke ʻano he mea buffering e hoʻoponopono i ka pH, Hoʻohana pinepine ʻia ma ke ʻano he ʻāpana no nā ʻano media like ʻole i hoʻohana ʻia i ka moʻomeheu o nā microorganism, ma ke ʻano he ʻāpana i loko o ka phosphate buffered saline (PBS). Loaʻa ia ma nā ʻano he nui: monobasic, dibasic, a me tribasic (K3PO4). ʻO ka hapa nui o nā hopena buffer potassium phosphate pH neutral i loaʻa nā hui ʻana o nā ʻano monobasic a me dibasic i nā kekelē like ʻole, ma muli o ka pH i makemake ʻia. ʻO nā buffers Gomori, nā buffers phosphate i hoʻohana pinepine ʻia, i loaʻa ka hui ʻana o ka monobasic dihydrogen phosphate a me ka dibasic monohydrogen phosphate. Ma ka hoʻololi ʻana i ka nui o kēlā me kēia paʻakai, hiki ke hoʻomākaukau ʻia kahi ʻano o nā buffers e buffer maikaʻi ma waena o ka pH 5.8 a me ka pH 8.0 (e ʻoluʻolu e nānā i nā papa ma lalo). Loaʻa i nā Phosphates kahi mana buffering kiʻekiʻe loa a hiki ke hoʻoheheʻe ʻia i ka wai.

1) ʻO ka potassium phosphate kahi mea hoʻoponopono acidity a me ka chelating agent (hoʻohana ʻia e hoʻopaʻa i nā ion metala). Kāohi ia i ka maloʻo ʻana a hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa waikawa i loko o nā pauka a me ka pale ʻana i ka hoʻokumu ʻia ʻana o nā puʻupuʻu. Hoʻonui ia i ka hana o nā antioxidants.
2) I loko o ka ʻoihana meaʻai (Nā mea hoʻohui meaʻai), hoʻohana ʻia ia ma ke ʻano he emulsifier, potassium fortifier, mea ʻono, mea hoʻopaʻa ʻiʻo. Kōkua ka potassium phosphate i ka hoʻopaʻa ʻana, ka mānoanoa a me ka hoʻoponopono ʻana i ka acidity a me ka makū i nā meaʻai. Wahi a ka hoʻolako ʻana o ka FAO (1984), ʻo kāna noi a me ka nui i kaupalena ʻia e like me kēia: ka hupa koke; ka paʻakai phosphate holoʻokoʻa: 1000 mg/kg (helu ʻia ma muli o P2O5); nā wāwae mua o ka puaʻa i kuke ʻia, ka ham, ka ʻiʻo minced i kuke ʻia 3g/kg (ka nui o ka hoʻohana hoʻokahi a i ʻole ka nui o ka hui pū ʻana me nā phosphate ʻē aʻe, i helu ʻia ma P2O5); ka pauka waiū haʻahaʻa haʻahaʻa, ka waiū condensed, ka kirīmi dilute: 2 g/kg (ka nui o ka hoʻohana hoʻokahi); ka nui o ka hui pū ʻana me nā mea hoʻopaʻa ʻē aʻe: 3 (helu ʻia ma ka mea anhydrous); ka pauka waiū, ka tīhi i hana ʻia: 5g/kg; ka tīhi i hana ʻia, ka nui o ka phosphate 9g/kg (helu ʻia ma ke ʻano he phosphorus); ka mea inu anu: 2g/kg (ka nui o ka hoʻohana hoʻokahi a i ʻole ka nui o ka hui pū ʻana me nā phosphate ʻē aʻe, i helu ʻia ma P2O5).
3) Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā huahana pasta me ka wai alkaline. Hiki ke hoʻohana ʻia no ka hana ʻana i ke kopa wai, ka pepa kiʻekiʻe, ka ʻaila i hoʻomaʻemaʻe ʻia, ka pepa kiʻekiʻe, ʻo ia ka phosphorus a me ka potassium fertilizers. Hiki ke hoʻohana ʻia e like me ka mea hoʻomālielie wai paila. Hoʻohana pū ʻia i ka lāʻau lapaʻau. I kekahi manawa hoʻohana ʻia ka potassium phosphate ma ke ʻano he lāʻau lapaʻau. Hiki iā ia ke loaʻa ka hopena diuretic a hana ma ke ʻano he laxative ke hoʻohana ʻia i nā nui lāʻau lapaʻau. Eia nō naʻe, hiki i ka phosphorus ke launa pū me kekahi mau lāʻau lapaʻau, me nā corticosteroids a me nā diuretics potassium-sparing, e hoʻonui ana i ka pilikia no nā hopena maikaʻi ʻole; e hoʻohana wale ia ke ʻōlelo ʻia e ke kauka.
4) Hiki ke hoʻohana ʻia e like me ka reagent analytical, buffer a me ka softener.
