He aha te whakarāpopototanga o te wehenga konutai hauwai-sulfide?
konutai hauwaiwhāiti Whakamutunga
Mā tēnei tikanga ka wehea tuatahitia ngā tote tioata pērā i te Na₂CO₃ mai i te otinga NaHS kukū. Kātahi ka whakapakeketia tika te NaHS·H₂O rewa hei maramara i roto i te pouaka whakamatao korehau i mua i te tākai aunoa. Nā reira, kua whakaitihia te nui o te poke Na₂CO₃ mai i te 2.4% ki te 0.3%. Ka puta te tukanga whakamatao i roto i te korehau, hei whakaiti i te waikura nā te hau e pāngia ana, ā, hei ārai hoki i te pirau o te hua. Ka whakahaerehia te tukanga purenga katoa i roto i tētahi pūnaha kati, hei ārai i te tukunga o ngā hau whakapataritari, hei karo hoki i te parahanga tuarua o te taiao. Ka tākai tikahia ngā maramara NaHS konutai hauwai sulfide, hei whakakore i te parahanga i te wā e rongoa ana. Hei tāpiri, he māmā noa iho tēnei tikanga, he iti noa ngā taputapu e hiahiatia ana, ā, he iti hoki te utu.
