Ko cyanuric acid inowedzera kana kuderedza pH here?

Mhinduro pfupi ndeyekuti hongu. Cyanuric acid inoderedza pH yemvura yedziva.

Asidhi yecyanuriciasidhi chaiyo uye pH ye 0.1% cyanuric acid solution iri 4.5. Hairatidzike kunge isina acid yakawanda nepo pH ye 0.1% sodium bisulfate solution iri 2.2 uye pH ye 0.1% hydrochloric acid iri 1.6. Asi ndapota cherechedza kuti pH yemadziva ekushambira iri pakati pe 7.2 ne 7.8 uye pKa yekutanga ye cyanuric acid iri 6.88. Izvi zvinoreva kuti mamorekuru mazhinji e cyanuric acid mudziva rekushambira anogona kuburitsa hydrogen ion uye kugona kwe cyanuric acid kuderedza pH kwakafanana zvikuru nekwe sodium bisulfate iyo inowanzo shandiswa semushonga wekuderedza pH.

Semuyenzaniso:

Kune dziva rekushambira rekunze. pH yekutanga yemvura yedziva i7.50, alkalinity yese i120 ppm nepo cyanuric acid level iri 10 ppm. Zvese zviri kushanda kunze kwe zero cyanuric acid level. Ngatiwedzerei 20 ppm ye dry cyanuric acid. Cyanuric acid inonyunguduka zvishoma nezvishoma, kazhinji inotora mazuva maviri kusvika matatu. Kana cyanuric acid yanyunguduka zvachose, pH yemvura yedziva ichave 7.12 iyo iri pasi pemuganhu wakaderera we pH (7.20). 12 ppm ye sodium carbonate kana 5 ppm ye sodium hydroxide inodiwa kuwedzera kugadzirisa dambudziko re pH.

Mvura yemonosodium cyanurate kana slurry inowanikwa mune mamwe zvitoro zvedziva. 1 ppm monosodium cyanurate inowedzera huwandu hwecyanuric acid ne 0.85 ppm. Monosodium cyanurate inonyungudika nekukurumidza mumvura, saka zviri nyore kushandisa uye inogona kuwedzera huwandu hwecyanuric acid mudziva rekushambira nekukurumidza. Kusiyana necyanuric acid, mvura yemonosodium cyanurate ine alkaline (pH ye35% slurry iri pakati pe8.0 kusvika 8.5) uye inowedzera zvishoma pH yemvura yedziva. Mudziva rataurwa pamusoro apa, pH yemvura yedziva yaizowedzera kusvika 7.68 mushure mekuwedzera 23.5 ppm yemonosodium cyanurate yakachena.

Musakanganwa kuti cyanuric acid ne monosodium cyanurate mumvura yedziva zvinoshandawo se buffers. Kureva kuti, kana cyanuric acid yakakwira, pH haichafambi zvakanaka. Saka ndapota yeukai kuyedzazve alkalinity yese kana pH yemvura yedziva ichidikanwa kuti igadziriswe.

Zivawo kuti cyanuric acid inochengetedza simba kupfuura sodium carbonate, saka kugadzirisa pH kunoda kuwedzera acid yakawanda kana alkali kupfuura pasina cyanuric acid.

Kana uchida dziva rekushambira rine pH yekutanga iri 7.2 uye pH inodiwa iri 7.5, alkalinity yese i120 ppm nepo cyanuric acid level iri 0, 7 ppm yesodium carbonate inodiwa kuti isangane nepH inodiwa. Chengeta pH yekutanga, pH inodiwa uye alkalinity yese iri 120 ppm isina kuchinja asi chinja cyanuric acid level kuenda ku50 ppm, 10 ppm yesodium carbonate inodiwa izvozvi.

Kana pH ichida kudzikiswa, cyanuric acid haina simba rakawanda. Padziva rekushambira rine pH yekutanga iri 7.8 uye pH inodiwa iri 7.5, alkalinity yese iri 120 ppm uye cyanuric acid level iri 0, 6.8 ppm yesodium bisulfate inodiwa kuti isangane nepH inodiwa. Chengeta pH yekutanga, pH inodiwa uye alkalinity yese iri 120 ppm isina kuchinja asi chinja cyanuric acid level kuenda ku50 ppm, 7.2 ppm yesodium bisulfate inodiwa - kuwedzera kwe6% chete kwedosi yesodium bisulfate.

Cyanuric acid ine mukana wekuti haizoumbike skero ine calcium kana dzimwe simbi.
