Nga Ahuatanga Matū: Karaihe papura kanapa me te paura parauri whero.Ira whakarewa 180-182 ℃.Wairewa ki te waiwaro, waikawa ahetiki hukapapa, tata korere ki te wai.
Nga Whakamahinga: Ko te Methyl whero tetahi o nga tohu waikawa-waahi e whakamahia nuitia ana, ko te kukū o mua ko te 0.1% wairewa waihano, pH4.4 (whero) -6.2 (kowhai).Ka whakamahia ano mo te whakapouri i roto i te vivo o te protozoa.
Te kaupapa: Te tae ora o Protozoa;te tohu waikawa-papa, te awhe pH rerekee o te 4.4 (whero) ki te 6.2 (kowhai);te titration o te haukini, nga turanga waro ngoikore me nga pāhare, engari kaore e pai mo nga waikawa waro i tua atu i te waikawa oxalic me te waikawa picric;ka taea te whakakotahi ki te Bromocresol matomato me te methylene puru he tohu whakauru hei whakapoto i te awhe huringa tae me te whakapai ake i te maaramatanga o te huringa tae;tohu whakaurunga mo te titration rerenga, penei i te titration o te katote fluoride me te thorium nitrate;te whakatau i te chlorine kore utu, te chlorite me etahi atu mea hāora
Whakamahinga: te poke ora o te protozoa, te tohu waikawa-turanga (pH4.4to6.2), te whakamatautau matū koiora pūmua haumanu.Ko te 4.4 (whero) -6.2 (kowhai) te awhe pH discoloration.Whakawetohia te haukini, nga turanga waro ngoikore me nga pāhare, engari kaua mo nga waikawa waro i tua atu i te waikawa oxalic me te waikawa picric.Ka taea te whakakotahi ki te bromocresol matomato me te puru methylene hei hanga i tetahi tohu whakauru hei whakapoto i te awhe huringa tae me te whakapai ake i te maaramatanga o te huringa tae.Ko nga tohu whakaurunga mo nga titrations rerenga, penei i te titration fluoride me te thorium nitrate.Te whakatau o te maota kore utu, te maaota me etahi atu mea hāora.
