Tirohanga Whānui mō te Hua:
Ka whakamahia e te aroturuki hauota nitrite ipurangi te spectrophotometry hei kimi. Ko te nuinga o tēnei taputapu e whakamahia ana mō te aroturuki i te wai mata, te wai whenua, te wai para ahumahi, me ētahi atu.
Ka taea e tēnei tātari te mahi aunoa, me te haere tonu, me te kore e wawaotia e te tangata mō te wā roa, i runga i ngā tautuhinga o te papaanga. He whānui te whakamahinga mō ngā āhuatanga rerekē pērā i te tukunga waipara mai i te pūtake parahanga ahumahi me te waipara tukanga ahumahi. E ai ki te uauatanga o ngā āhuatanga whakamātautau o te papaanga, ka taea te whiriwhiri i ngā pūnaha maimoatanga-mua e rite ana hei whakarite i te pono o te tukanga whakamātautau me te tika o ngā hua whakamātautau, me te whakatutuki katoa i ngā whakaritenga o te papaanga o ngā wā rerekē.
Te Kaupapa Hua:I roto i te reo waikawa phosphoric i te pH 1.8± 0.3, ka tauhohe te nitrite ki te sulfanilamide hei hanga i te tote diazonium. Kātahi ka honoa tēnei tote ki te N-(1-Naphthyl) ethylenediamine dihydrochloride hei hanga i te tae whero, e whakaatu ana i te mimiti mōrahi i te roangaru o te 540 nm.

| 13 | Te mahi a te tangata me te mīhini | Whakaaturanga mata pa me te whakauru whakahau |
| 14 | Te tiakitanga tirotiro-ā-koe | Ka tātaritanga-ā-unoa te taputapu i tōna āhua mahi. Kāore e ngaro ngā raraunga mēnā he rerekētanga, he motuhanga hiko rānei. I muri i te tautuhi anō i te hiko, i te tīmatanga anō rānei o te hiko, ka tangohia aunoatia e te taputapu ngā toenga matū ka tīmata anō te mahi. |
| 15 | Te rokiroki raraunga | Te rokiroki raraunga 5-tau |
| 16 | Tiaki pāwhiri-kotahi | Whakakorehia aunoatia ngā matū tawhito, ka horoia ngā paipa; whakakapihia ngā matū hou, whakatikatika aunoatia, ka manatoko aunoatia; ka taea e te otinga horoi whiriwhiri te horoi aunoa i te pūtau nakunaku me te ngongo ine. |
| 17 | Te patuiro tere | Whakatutuki i te mahi kore e tirotirohia, e kore e mutu, ka whakaoti aunoa i ngā pūrongo patuiro, ka nui te āwhina i ngā kaiwhakamahi me te whakaiti i ngā utu mahi. |
| 18 | Atanga whakauru | Huri rahinga |
