Tripotassium phosphate K3PO4 CAS 7778-53-2 urwego rw'ibiribwa
Ibisobanuro by'igicuruzwa
Fosfeti ya potasiyumu ni reagent ifite ubushobozi bwo gufunga cyane, Ikora nk'igikoresho cyo gufunga kugira ngo igenzure pH, Ikunze gukoreshwa nk'igice cy'ubwoko butandukanye bw'ibintu bikoreshwa mu gukwirakwiza udukoko, nk'igice kiri muri saline ya fosfeti ifunga (PBS). Iboneka mu buryo butandukanye: monobasic, dibasic, na tribasic (K3PO4). Inyinshi mu bisubizo bya phosphate ya potasiyumu idafite pH igizwe n'uruvange rw'ubwoko bwa monobasic na dibasic ku rugero rutandukanye, bitewe na pH wifuza. Fosfeti ya Gomori, phosphate buffers ikoreshwa cyane, igizwe n'uruvange rwa monobasic dihydrogen phosphate na dibasic monohydrogen phosphate. Mu guhindura ingano ya buri munyu, hashobora gutegurwa amoko atandukanye y'ibice bifunga neza hagati ya pH 5.8 na pH 8.0 (reba imbonerahamwe iri hepfo). Fosfeti zifite ubushobozi bwo gufunga cyane kandi zishongesha cyane mu mazi.

Porogaramu
1) Fosifate ya potasiyumu ni umusemburo ugenzura aside n'uburyo bwo gukurura (ukoreshwa mu gufata iyoni z'icyuma). Irinda ko ibintu bicika kandi ikoreshwa nk'umusemburo uhoraho mu ifu ndetse no gukumira ko habaho uduce duto. Yongera imikorere ya antioxydants.
2) Mu nganda z'ibiribwa (inyongeramusaruro ku biribwa), ikoreshwa nk'inyunganizi, ikungahaza potasiyumu, uburyohe, n'inyunganizi y'inyama. Fosifate ya potasiyumu ifasha gutuza, gukurura no kugena aside n'ubushuhe mu biribwa. Dukurikije amabwiriza ya FAO (1984), ikoreshwa ryayo n'ingano yayo ni ibi bikurikira: umufa w'ako kanya; umunyu wa fosifate wose: 1000 mg/kg (ubazwe hashingiwe kuri P2O5); amaguru y'ingurube atetse, inyama y'ingurube, inyama zitetse zitetse 3g/kg (ingano ikoreshwa rimwe cyangwa ivanze n'indi fosifate, ibazwe kuri P2O5); ifu y'amata yuzuye, amata afunze, amavuta asukuye: 2 g/kg (ingano ikoreshwa rimwe); ingano ivanze n'indi ikungahaza: 3 (ibazwe ku kintu kidakoreshwa); ifu y'amata, foromaje yatunganyijwe: 5g/kg; foromaje yatunganyijwe, ingano yose ya fosifate 9g/kg (ibazwe nka fosifate); ikinyobwa gikonje: 2g/kg (ingano ikoreshwa rimwe cyangwa ivanze n'indi fosifate, ibazwe kuri P2O5).
3) Ishobora gukoreshwa mu gutegura ibikomoka kuri makaroni hakoreshejwe amazi ya alkaline. Ishobora gukoreshwa mu gukora isabune y'amazi, impapuro nziza, lisansi itunganyijwe, impapuro nziza, ikaba ifumbire ya fosifore na potasiyumu. Ishobora gukoreshwa nk'ifumbire yoroshya amazi mu byuma bishyushya. Ikoreshwa kandi mu buvuzi. Fosifore ya potasiyumu rimwe na rimwe ikoreshwa nk'umuti. Ishobora kugira ingaruka zo gusukura amaraso no gukora nk'umuti woroshya iyo ikoreshejwe mu buvuzi. Ariko, fosifore ishobora kugira ingaruka ku miti imwe n'imwe, harimo na corticosteroids na diuretics zigabanya potasiyumu, byongera ibyago byo kugira ingaruka mbi; ikoreshe gusa iyo umuganga abigusabye.
4) Ishobora gukoreshwa nk'igikoresho cyo gusesengura, uburyo bwo gufunga no koroshya.
