He aha ngā Tikanga Matua mō te Ine i te Hāora Wairewa i roto i te Wai?

Ko te tikanga tirotiro hikohiko e mahi ana i runga i te kaupapa e horapa ana ngā ngota hāora mā roto i tētahi kiriuhi whiriwhiri, ā, ka whakaitihia i te hikohiko mahi, ka puta he ia horapa e ōrite ana ki te kukū hāora. Mā te ine i tēnei ia, ka taea te whakatau tika i te kukū hāora rewa i roto i te tauira. Ka arotahi tēnei pepa ki ngā tikanga whakahaere me ngā mahi tiaki e pā ana ki te tikanga tirotiro hikohiko, e whai ana kia whakarei ake i te māramatanga ki ngā āhuatanga mahi taputapu me te whakapai ake i te tika o te ine.

1. Ngā Taputapu me ngā Tauhohenga
Ngā taputapu matua: te tātari kounga wai maha-mahi
Ngā matū tauhohenga: ko ērā e hiahiatia ana mō te whakatau iodometric o te hāora rewa

2. Te Whakatikatika Katoa o te Mita Hāora Whakarewa
Tikanga Taiwhanga 1 (Tikanga Hau-Wai Kūkū): I te pāmahana rūma whakahaeretia o te 20 °C, ringihia te 1 rita o te wai tino parakore ki roto i te kapu 2 rita. Whakahaungia te otinga kia hau tonu mō ngā hāora e 2, kātahi ka mutu te hau, ka waiho kia tau te wai mō ngā meneti e 30. Tīmatahia te whakataurite mā te whakanoho i te ine ki roto i te wai, me te whakaoho mā te whakamahi i te whakaoho aukume i te 500 rpm, te neke mārire rānei i te hiko i roto i te wāhanga wai. Tīpakohia te "whakataurite hau-wai kūkū" i te atanga taputapu. Kia oti, me tohu te pānui tauine katoa i te 100%.

Tikanga Taiwhanga 2 (Tikanga Hau Mākū-Wai): I te 20 °C, whakamakukuhia te hautai i roto i te ringaringa tiaki o te whakamātautau kia tino mākū. Āta pania te mata o te kiriuhi hiko ki te pepa tātari hei tango i te makuku nui, tāpirihia anō te hiko ki roto i te ringaringa, ā, waiho kia taurite mō te 2 hāora i mua i te tīmatanga o te whakatikatika. Tīpakohia te "whakatikatika hau mākū-wai" i te atanga taputapu. Kia oti, ka eke te pānui tauine katoa ki te 102.3%. I te nuinga o te wā, ko ngā hua i puta mai i te tikanga hau mākū-wai he rite ki ērā mai i te tikanga hau mākū-wai. Ko ngā inenga i muri mai o tētahi o ngā reo e rua ka puta he uara tata ki te 9.0 mg/L.

Whakatikatika Marae: Me whakatikatika te taputapu i mua i ia whakamahinga. I te mea he maha ngā wā ka rerekē te pāmahana o waho mai i te 20 °C, he pai ake te mahi whakatikatika mara mā te whakamahi i te tikanga hau kua mākū ki te wai i roto i te ringaringa tirotiro. Ko ngā taputapu kua whakatikatikaina mā te whakamahi i tēnei huarahi ka kitea he hapa ine i roto i ngā rohe e whakaaetia ana, ā, ka noho tonu hei whakamahi mara.

3. Te Whakatikatika i te Pūwāhi Kore
Whakaritea he otinga kore-hāora mā te whakarewa i te 0.25 karamu o te konutai whanariki (Na₂SO₃) me te 0.25 karamu o te cobalt(II) chloride hexahydrate (CoCl₂·6H₂O) ki roto i te 250 mL o te wai tino parakore. Rukuhia te pūwero ki roto i tēnei otinga ka whakaoho mārire. Tīmatahia te whakatikatika ira-kore, ā, tatari kia tau te pānui i mua i te whakaū i te otinga. Kāore e hiahiatia he whakatikatika ā-ringa mō ngā taputapu whai utu kore aunoa.
