Amsar a takaice ita ce eh. Cyanuric acid zai rage pH na ruwan tafkin.
Cyanuric acid shine ainihin acid kuma pH na 0.1% cyanuric acid bayani shine 4.5. Ba ze zama acidic sosai ba yayin da pH na 0.1% sodium bisulfate bayani shine 2.2 kuma pH na 0.1% hydrochloric acid shine 1.6. Amma don Allah a lura cewa pH na wuraren waha yana tsakanin 7.2 da 7.8 kuma pKa na farko na cyanuric acid shine 6.88. Wannan yana nufin cewa yawancin kwayoyin cyanuric acid a cikin tafkin suna iya sakin hydrogen ion kuma ikon cyanuric acid zuwa ƙananan pH yana kusa da na sodium bisulfate wanda yawanci ana amfani dashi azaman mai rage pH.
Misali:
Akwai wurin wanka na waje. Farkon pH na ruwan tafkin shine 7.50, jimlar alkalinity shine 120 ppm yayin da matakin cyanuric acid shine 10 ppm. Komai yana cikin tsari sai dai matakin cyanuric acid sifili. Bari mu ƙara 20 ppm na busassun cyanuric acid. Cyanuric acid yana narkewa a hankali, yawanci yana ɗaukar kwanaki 2 zuwa 3. Lokacin da aka narkar da acid cyanuric gaba ɗaya pH na ruwan tafkin zai zama 7.12 wanda ya yi ƙasa da ƙaƙƙarfan shawarar ƙarancin pH (7.20). Ana buƙatar 12 ppm na sodium carbonate ko 5 ppm na sodium hydroxide don ƙara don daidaita matsalar pH.
Monosodium cyanurate ruwa ko slurry yana samuwa a wasu shagunan tafki. 1 ppm monosodium cyanurate zai ƙara matakin cyanuric acid da 0.85 ppm. Monosodium cyanurate yana da sauri mai narkewa a cikin ruwa, don haka ya fi dacewa don amfani kuma yana iya haɓaka matakan cyanuric acid da sauri a cikin tafkin. Sabanin acid cyanuric, monosodium cyanurate ruwa shine alkaline (pH na 35% slurry yana tsakanin 8.0 zuwa 8.5) kuma dan kadan yana ƙara pH na ruwan tafkin. A cikin tafkin da aka ambata a sama, pH na ruwan tafkin zai ƙaru zuwa 7.68 bayan ƙara 23.5 ppm na monosodium cyanurate zalla.
Kar a manta cewa cyanuric acid da monosodium cyanurate a cikin ruwan tafkin suma suna aiki azaman masu buffers. Wato, mafi girman matakin cyanuric acid, ƙarancin yuwuwar pH zai yi nisa. Don haka da fatan za a tuna don gwada jimlar alkalinity lokacin da ake buƙatar pH na ruwan tafkin don daidaitawa.
Har ila yau lura cewa cyanuric acid yana da ƙarfi fiye da sodium carbonate, don haka daidaitawar pH yana buƙatar ƙara yawan acid ko alkali fiye da ba tare da cyanuric acid ba.
Don wurin shakatawa wanda pH na farko shine 7.2 kuma pH da ake so shine 7.5, jimlar alkalinity shine 120 ppm yayin da matakin cyanuric acid shine 0, 7 ppm na sodium carbonate ana buƙata don saduwa da pH da ake so. Rike pH na farko, pH da ake so da jimlar alkalinity shine 120 ppm ba canzawa amma canza matakin cyanuric acid zuwa 50 ppm, 10 ppm na sodium carbonate ana buƙatar yanzu.
Lokacin da ake buƙatar saukar da pH, cyanuric acid yana da ƙarancin tasiri. Don wurin shakatawa wanda pH na farko shine 7.8 kuma pH da ake so shine 7.5, jimlar alkalinity shine 120 ppm kuma matakin cyanuric acid shine 0, 6.8 ppm na sodium bisulfate ana buƙata don saduwa da pH da ake so. Rike pH na farko, pH da ake so da jimlar alkalinity shine 120 ppm ba canzawa amma canza matakin cyanuric acid zuwa 50 ppm, 7.2 ppm na sodium bisulfate ana buƙatar - kawai ƙarar 6% na adadin sodium bisulfate.
Cyanuric acid kuma yana da fa'ida cewa ba zai samar da sikeli tare da alli ko wasu karafa ba.
