Ko cyanuric acid inokwidza kana kuderedza pH?

Mhinduro pfupi ndihongu. Cyanuric acid inoderedza pH yemvura yedziva.

Cynuric acidiasidhi chaiyo uye pH ye0.1% cyanuric acid mhinduro ndeye 4.5. Hairatidziki kunge ine acidic zvakanyanya nepo pH ye0.1% sodium bisulfate solution iri 2.2 uye pH ye0.1% hydrochloric acid iri 1.6. Asi ndapota cherechedza kuti pH yemadziva ekushambira iri pakati pe7.2 ne7.8 uye pKa yekutanga yecyanuric acid i6.88. Izvi zvinoreva kuti mamorekuru akawanda ecyanuric acid ari mudziva rekushambira anogona kuburitsa hydrogen ion uye kugona kwecyanuric acid kudzikisa pH iri padyo neiyo sodium bisulfate iyo inowanzo shandiswa se pH inoderedza.

Semuyenzaniso:

Pane dziva rekunze rekutuhwina. Iyo yekutanga pH yemvura yedziva i7.50, iyo yakazara alkalinity i120 ppm nepo cyanuric acid level iri gumi ppm. Zvese zviri muhurongwa hwekushanda kunze kweiyo zero cyanuric acid level. Ngatiwedzerei 20 ppm yakaoma cyanuric acid. Cyanuric acid inonyungudika zvishoma nezvishoma, kazhinji inotora mazuva maviri kusvika matatu. Kana cyanuric acid yanyungudika zvachose pH yemvura yedhamu inenge iri 7.12 iyo yakadzikira pane inokurudzirwa yakaderera muganho wepH (7.20). 12 ppm ye sodium carbonate kana 5 ppm ye sodium hydroxide inodiwa kuwedzera kugadzirisa pH dambudziko.

Monosodium cyanrate fluid kana slurry inowanikwa mune mamwe zvitoro zvemadziva. 1 ppm monosodium cyanurate ichawedzera cyanuric acid level ne 0.85 ppm. Monosodium cyanrate inokurumidza kunyungudika mumvura, saka iri nyore kushandisa uye inogona kukurumidza kuwedzera cyanuric acid mazinga mudhibhi rekushambira. Kusiyana necyanuric acid, monosodium cyanurate liquid is alkaline (pH ye35% slurry iri pakati pe8.0 kusvika 8.5) uye inowedzera zvishoma pH yemvura yemvura. Mudziva rataurwa pamusoro, pH yemvura yedhamu yaizokwira kusvika pa7.68 mushure mekuwedzera 23.5 ppm ye pure monosodium cyanrate.

Usakanganwa kuti cyanuric acid uye monosodium cyanrate mumvura yedziva zvakare inoshanda semabhafa. Ndiko kuti, iyo yakakwira iyo cyanuric acid level, zvishoma zvinoita kuti pH ikukure. Saka ndapota yeuka kudzokorora iyo yakazara alkalinity kana pH yemvura yedziva ichidikanwa kugadzirisa.

Ziva zvakare kuti cyanuric acid isimbi yakasimba kudarika sodium carbonate, saka kugadzirisa pH kunoda kuwedzera asidhi yakawanda kana alkali pane isina cyanuric acid.

Kune dziva rekushambira umo pH yekutanga iri 7.2 uye pH inodiwa i7.5, iyo yakazara alkalinity i120 ppm nepo cyanuric acid level iri 0, 7 ppm yesodium carbonate inodiwa kusangana nepH inodiwa. Chengeta pH yekutanga, pH inodiwa uye iyo alkalinity yakazara ndeye 120 ppm isina kuchinjwa asi shandura iyo cyanuric acid level kusvika 50 ppm, 10 ppm ye sodium carbonate inodiwa ikozvino.

Kana pH inoda kudzikiswa, cyanuric acid ine zvishoma. Kune dziva rekushambira umo pH yekutanga iri 7.8 uye pH inodiwa i7.5, iyo yakazara alkalinity i120 ppm uye iyo cyanuric acid level i0, 6.8 ppm ye sodium bisulfate inodiwa kuti isangane nepH inodiwa. Chengetedza pH yekutanga, pH yaidiwa uye alkalinity yose ndeye 120 ppm isina kuchinjwa asi shandura chiyero checyanuric acid kusvika ku50 ppm, 7.2 ppm ye sodium bisulfate inodiwa - chete 6% kuwedzera kwechiyero che sodium bisulfate.

Cyanuric acid inewo mukana wekuti haizogadziri chikero necalcium kana mamwe masimbi.
