Te Hanganga o te Hauwaihaupū Konutai mā te Konutai Etohaiti me te H2S
Te Whakarite mā te Konutai Etohaiti me te Hauhāora Maroke
Tatūnga Taputapu:
Ka whakakīia he pounamu 150 mL me te ringa taha ki 20 mL o te wai hou kua whakatōtōtia Etanora Korewai me 2 karamu o ngā konganuku konutai ma (kāore he paparanga waikura).
Kei roto i te pounamu he pūwhakamātao reflux me he ngongo whakamaroke, ā, kua hiritia te taha taha mō tētahi wā poto.
I muri i te tīmatanga o te hanganga o te konutai etoksina, ka tāpirihia he 40 mL o te etanoru kore wai ka tāpirihia i roto i ngā wāhanga tae noa ki te memeha katoa.
Tauhohenga ki te H₂S Maroke:
Ka whakauruhia he ngongo karāhe mā te taha o te ringa ki roto i te wairewa, ā, ka pupuhihia te hau H₂S maroke (kia tika te ārai i te hau kia kore ai e uru te hau).
Ka whakakīia te otinga ki te H₂S, kātahi ka tātarihia hei tango i ngā matūriki.
Ka whakawhitia te tātari ki tētahi pounamu kōniko maroke, ā 50 mL o te etera tino ka tāpirihia, ka puta tonu mai te NaHS mā.
Ka tāpirihia he etera anō (~110 mL katoa) i ngā wāhanga kia kore ra ano e puta he maturuturunga anō.
Ka tere te tātari i te matūriki, ka horoia kia 2–3 ngā wā ki te etera tino, kātahi ka whakamarokehia i raro i te korehau.
He parakore tātari te hua. Mō te parakore teitei ake, ka taea te mahi i te whakakōhatu anō mai i te etanoru/etera.
