Ngā Tohutohu mō te Whakamahinga o te Hinu Whakahinuhinu Tauhohenga Tātari Uara Waikawa Katoa

【Te Kaupapa Whakamātautau】

Ka whakamahia tēnei tikanga hei whakatau i te waikawa, i te hanganga taketake rānei o ngā hinu whakahinuhinu ka wairewa i roto i te isopropyl ethanol me te toluene. Ka taea te whakamahi hei whakatau i ngā panonitanga o te hinu whakahinuhinu i raro i ngā āhuatanga waikura. Ka whakanohoia he nui o te tauira hinu whakahinuhinu ki roto i te whakarewa titration, ā, ko te otinga tohu i roto i te pounamu whakamātautau he otinga naphthol; ka huri te tae mai i te kikorangi ki te kakariki, kātahi ki te karaka.

【Ngā Taonga kei roto】

Pūwero whakamātautau x 1 2. Paipa tauira x 1 3. Pepa whakakoi hinu x 1

【Ngā whakaritenga tauira hinu】

1. I te wā e tango ana i ngā tauira hinu whakahinuhinu, whakamahia ngā pounamu tauira maroke, kore wai hei karo i te poke tuarua mai i te wai.

2. I te wā e whakahaerehia ana ngā whakamātautau, me whakamahi ngā tauira hou i tangohia i ngā wā katoa e taea ai, ā, me tīmata te ine i te ine i muri i te hokinga o ngā tauira ki te pāmahana rūma.

【Ngā Tikanga Whakamātautau】

I mua i te whakahaere i tētahi whakamātautau, me pānui katoa te pukapuka tohutohu. I mua i te whakamahinga, me whakahoki te hua me te tauira hinu whakahinuhinu hei whakamātautau ki te pāmahana rūma.

1. Whakamahia he pipette hei kohi i te tauira hinu whakahinuhinu hei whakamātautau.

2. Whai muri i te murunga i te mata o te pipette, whakatuwheratia te taupoki o te pounamu matū ka tāpirihia kia tekau ngā pata o te tauira hei whakamātautau ki roto i te matū.

3. Taupokina te pounamu matū hohenga, ka rūrū kia tika kia tino konatunatua te tauira hinu whakahinuhinu ki te matū hohenga.

4. Taria kia rerekē te tae o te matū; me pānui te hua whakamātautau i roto i te 2-3 meneti.

(Kia mōhio: Kaua e neke atu i te rahinga o tēnei pounamu matū. Kia tūpato.)

【Whakamahinga】

1. Hei whakamahi kotahi anake tēnei matū i te wā e whakamātautau ana i te papaanga.

2. Hei tirotiro noa i ngā hua kounga tēnei matū; me whakaū te kitenga waikura mā te whakamātautau tauanga.

3. E pā ana tēnei ki ngā wā ka pakaru te hinu whakahinuhinu nā te waikura i raro i te whakamahinga noa. Heoi, tērā pea kāore i te tino tika mō ngā wā ka pakaru te hinu whakahinuhinu nā te emulsification.

4. Me pānui ngā hua o te whakamātautau i roto i ngā meneti e 2-3. Hei ārai i ngā tauhohenga teka, ka kore e whai mana ngā hua mēnā kua hipa neke atu i te 30 meneti mai i te tāpiritanga o te tauira.
