Acide cyanuric izamura cyangwa igabanya pH?

Igisubizo kigufi ni yego. Acide Cyanuric izagabanya pH y'amazi ya pisine.

Acide ya Cyanuric ni aside nyayo kandi pH ya 0.1% yumuti wa cyanuric ni 4.5. Ntabwo bisa nkaho ari acide cyane mugihe pH yumuti wa 0.1% sodium bisulfate yumuti ari 2.2 naho pH ya 0.1% acide hydrochloric ni 1.6. Ariko nyamuneka menya ko pH yibidendezi biri hagati ya 7.2 na 7.8 naho pKa yambere ya acide cyanuric ni 6.88. Ibi bivuze ko molekile nyinshi ya acide ya cyanuric muri pisine ishobora kurekura hydrogene ion kandi ubushobozi bwa acide cyanuric yo kugabanya pH yegeranye cyane nubwa sodium bisulfate isanzwe ikoreshwa nkigabanya pH.

Urugero:

Hano hari pisine yo hanze. PH ibanza y'amazi ya pisine ni 7.50, alkalinity yose ni 120 ppm mugihe urwego rwa acide cyanuric ari 10 ppm. Ibintu byose biri murutonde usibye urwego rwa zeru cyanuric. Reka twongere 20 ppm ya acide cyanuric yumye. Acide Cyanuric irashonga buhoro, mubisanzwe bifata iminsi 2 kugeza kuri 3. Iyo aside ya cyanuric imaze gushonga burundu pH yamazi ya pisine azaba 7.12 ari munsi yumubare muto wa pH (7.20). 12 ppm ya sodium karubone cyangwa 5 ppm ya sodium hydroxide irakenewe kugirango wongere kugirango uhindure ikibazo cya pH.

Monosodium cyanurate fluid cyangwa slurry iraboneka mububiko bwa pisine. 1 ppm monosodium cyanurate izongera aside ya cyanuric kuri 0,85 ppm. Monosodium cyanurate irashobora gushonga vuba mumazi, kubwibyo biroroshye kuyikoresha kandi irashobora kongera umuvuduko wa acide cyanuric muri pisine. Bitandukanye na acide ya cyanuric, amazi ya monosodium cyanurate ni alkaline (pH ya 35% ya slurry iri hagati ya 8.0 kugeza 8.5) kandi yongerera gato pH y'amazi ya pisine. Muri pisine yavuzwe haruguru, pH y'amazi ya pisine yakwiyongera kugera kuri 7.68 nyuma yo kongeramo 23.5 ppm ya monosodium cyanurate.

Ntiwibagirwe ko acide cyanuric na monosodium cyanurate mumazi ya pisine nayo ikora nka buffer. Nukuvuga ko urwego rwinshi rwa acide cyanuric, niko pH idashobora kugenda. Nyamuneka nyamuneka wibuke gusubiramo alkalinity yose mugihe pH y'amazi ya pisine akenewe kugirango uhindure.

Menya kandi ko aside ya cyanuric ari buffer ikomeye kuruta karubone ya sodium, bityo rero guhinduranya pH bisaba kongeramo aside nyinshi cyangwa alkali kuruta kutagira aside ya cyanuric.

Kuri pisine yo koga aho pH ibanza ari 7.2 naho pH yifuzwa ni 7.5, alkalinity yose ni 120 ppm mugihe urwego rwa acide cyanuric ari 0, 7 ppm ya sodium karubone ikenewe kugirango pH yifuza. Komeza pH yambere, pH yifuzwa hamwe na alkalinity yose ni 120 ppm idahindutse ariko uhindure urwego rwa acide cyanuric kuri 50 ppm, 10 ppm ya sodium karubone irakenewe ubu.

Iyo pH ikeneye kugabanuka, acide cyanuric igira ingaruka nke. Kuri pisine yo koga aho pH ibanza ari 7.8 naho pH yifuzwa ni 7.5, alkalinity yose ni 120 ppm naho aside ya cyanuric ni 0, 6.8 ppm ya sodium bisulfate irakenewe kugirango pH yifuza. Komeza pH yambere, pH yifuzwa hamwe na alkalinity yose hamwe ni 120 ppm idahindutse ariko uhindure urwego rwa acide cyanuric kuri 50 ppm, 7.2 ppm ya sodium bisulfate irakenewe - kwiyongera kwa 6% gusa ya dosiye ya sodium bisulfate.

Acide ya Cyanuric nayo ifite akarusho ko itazakora igipimo hamwe na calcium cyangwa ibindi byuma.
