He reagent motuhake mo te whakatau i te formaldehyde me etahi atu matū tauhohenga.Ko te tikanga 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (AHMT) he pai te motuhake me te whiriwhiri, a ka taea te whakamahi i roto i te maha o nga aldehydes penei i te acetaldehyde, propionaldehyde, butyraldehyde, me te phenylacetaldehyde .Ko nga tikanga noho tahi e kore e whakararu i te whakatau, a koinei te tikanga pai mo te whakatau i te formaldehyde i roto i te wai inu me te wai puna.

Ko te tikanga 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (AHMT) e pa ana ki te taiao taiwhanga, te mahi o te tukanga urupare, te whiriwhiringa o nga rauemi me nga reagents me etahi atu mea.

Ko te paanga o te taiao ko te nuinga na te mea he wairewa te formaldehyde ki te wai, he ahua pumau ki te wai.Mena he tiketike rawa te kukū o te formaldehyde i te rangi, he ngawari te whakauru i te pokanoa me te parahanga ki te uara ine o te formaldehyde i roto i te wai.No reira, i te wa e whakamahi ana i te wairewa paerewa formaldehyde me te whakarite i te kurupae paerewa, me whakaitihia te wa whakamohiotanga, me kati te mono i muri i te whakamahinga.Me whakatuwherahia te matapihi mo te hau i mua i te mutunga o te whakamatautau kotahi me te tiimata o te whakamatautau ka whai ake.

Te awe o te tukanga tauhohenga: I muri i te whakatuwheratanga o te reagent, me whakamahi wawe tonu, me te aro nui ki te kati i te hiri i te wa.Ko te otinga kua oti te whakarite me penapena ki roto i te pounamu parauri pouri.I tua atu, ko te wai whakauru ka whakaputa i nga mirumiru hau i roto i te wa poto, a me tino wiri te mahi ki te karo i te hua o te ine i te uara absorbance ka pa, ka kore e pumau.Me tohu ano ko te wa wiri, te kaha, te waahi waahi me nga tikanga inenga tae o te tauira matapo, tauira tohutoro, me nga raupapa paerewa o nga ngongo tae.
