Shin cyanuric acid yana ƙaruwa ko rage pH?

Amsar a takaice ita ce eh. Cyanuric acid zai rage pH na ruwan tafkin.

Sinadarin siyanuricainihin acid ne kuma pH na maganin cyanuric acid 0.1% shine 4.5. Da alama ba shi da acid sosai yayin da pH na maganin sodium bisulfate 0.1% shine 2.2 kuma pH na 0.1% hydrochloric acid shine 1.6. Amma a lura cewa pH na wuraren ninkaya yana tsakanin 7.2 da 7.8 kuma pKa na farko na cyanuric acid shine 6.88. Wannan yana nufin cewa yawancin ƙwayoyin cyanuric acid a cikin wurin ninkaya na iya sakin ion hydrogen kuma ikon cyanuric acid don rage pH yana da kusanci da na sodium bisulfate wanda yawanci ana amfani da shi azaman mai rage pH.

Misali:

Akwai wurin waha a waje. pH na farko na ruwan wurin waha shine 7.50, jimlar alkalinity shine 120 ppm yayin da matakin cyanuric acid shine 10 ppm. Komai yana aiki ba tare da sifili matakin cyanuric acid ba. Bari mu ƙara 20 ppm na busasshen cyanuric acid. Cyanuric acid yana narkewa a hankali, yawanci yana ɗaukar kwanaki 2 zuwa 3. Idan cyanuric acid ya narke gaba ɗaya, pH na ruwan wurin waha zai zama 7.12 wanda ya fi ƙasa da ƙayyadadden pH da aka ba da shawarar (7.20). Ana buƙatar 12 ppm na sodium carbonate ko 5 ppm na sodium hydroxide don ƙarawa don daidaita matsalar pH.

Ana samun ruwa ko slurry na Monosodium cyanurate a wasu shagunan wanka. 1 ppm monosodium cyanurate zai ƙara matakin cyanuric acid da 0.85 ppm. Monosodium cyanurate yana narkewa cikin sauri a cikin ruwa, don haka ya fi dacewa a yi amfani da shi kuma yana iya ƙara matakan cyanuric acid cikin sauri a cikin wurin wanka. Sabanin cyanuric acid, ruwan monosodium cyanurate alkaline ne (pH na 35% slurry yana tsakanin 8.0 zuwa 8.5) kuma yana ƙara ɗan pH na ruwan wanka. A cikin wurin wanka da aka ambata a sama, pH na ruwan wanka zai ƙaru zuwa 7.68 bayan ƙara 23.5 ppm na tsantsar monosodium cyanurate.

Kar a manta cewa sinadarin cyanuric acid da monosodium cyanurate a cikin ruwan tafkin suma suna aiki azaman masu hana ruwa shiga. Wato, idan matakin cyanuric acid ya yi yawa, to pH ɗin zai ragu. Don haka a tuna a sake gwada cikakken alkalinity lokacin da ake buƙatar pH na ruwan tafkin don daidaitawa.

Haka kuma a lura cewa cyanuric acid yana da ƙarfi fiye da sodium carbonate, don haka daidaita pH yana buƙatar ƙara ƙarin acid ko alkali fiye da ba tare da cyanuric acid ba.

Ga wurin waha inda pH na farko yake 7.2 kuma pH da ake so shine 7.5, jimlar alkalinity shine 120 ppm yayin da matakin cyanuric acid shine 0, ana buƙatar 7 ppm na sodium carbonate don biyan pH da ake so. A kiyaye pH na farko, pH da ake so da jimlar alkalinity shine 120 ppm ba tare da canzawa ba amma a canza matakin cyanuric acid zuwa 50 ppm, ana buƙatar 10 ppm na sodium carbonate yanzu.

Idan pH ɗin ya kamata a rage, sinadarin cyanuric acid ba shi da tasiri sosai. Ga wurin waha inda pH ɗin farko yake 7.8 kuma pH ɗin da ake so shine 7.5, jimlar alkalinity shine 120 ppm kuma matakin cyanuric acid shine 0, ana buƙatar 6.8 ppm na sodium bisulfate don biyan buƙatun pH ɗin da ake so. A kiyaye pH ɗin farko, pH ɗin da ake so da jimlar alkalinity shine 120 ppm ba tare da canzawa ba amma a canza matakin cyanuric acid zuwa 50 ppm, ana buƙatar 7.2 ppm na sodium bisulfate - ƙarin kashi 6% ne kawai na yawan sinadarin sodium bisulfate.

Cyanuric acid kuma yana da fa'ida cewa ba zai samar da sikeli tare da alli ko wasu karafa ba.
