Waikawa Whāwhā Waikawa Whero
Te Whakamahinga o te Waikawa Whāriki me te Waikawa Pōrohi
Ka purea te waikawa whanariki para me te waikawa phosphoric hei whakaputa i ngā hua waikawa whanariki me te waikawa phosphoric kua tohua. Ko te waikawa whanariki te mea nui e whakamahia ana i roto i ngā ahumahi pēnei i te purenga o te hinu, te whakarewa whakarewa, me ngā tae. He maha te whakamahinga hei matū matū, ā, i roto i te hanga rauropi, ka taea te whakamahi hei matū whakamaroke me te matū whakapūkawa. Ko te waikawa phosphoric te mea nui e whakamahia ana i roto i ngā ahumahi rongoā, kai, tongi me ētahi atu, ā, ka taea hoki te whakamahi hei matū matū.
Te Hangarau Wehewehenga me te Hangarua Kore-Paraoa a Gaoke
Ko te tukanga mimiti kua arotauhia i Haina e whakamahia ana hei pure i te waikawa phosphoric para kia tutuki ai ngā paerewa whakamahinga ā-ahumahi; ko te tukanga wetewete catalytic e whakamahia ana hei pure i te waikawa whanariki para kia tutuki ai ngā whakaritenga whakamahinga ā-ahumahi. Ko te kaha tukatuka ā-tau o ngā waikawa me te kawakore para e neke atu i te 30,000 tana.
He aha i whiriwhiri ai i te tiaki taiao o Gaoke
Hei whakatutuki i te arataki hangarau me te auahatanga, he nui te aro o te kamupene ki te rangahau me te whanaketanga taketake me te auahatanga hangarau. I tēnei wā, e 350 mita pūrua te rahi o te rūma rangahau a te kamupene, me te haumi katoa neke atu i te 5 miriona yuan ki ngā taputapu whakamātautau. He taputapu kimi me te whakamātautau katoa, pērā i te ICP-MS (Thermo Fisher Scientific), te chromatograph hau (Agilent), te tātari matūriki wai (Riyin, Hapani), me ētahi atu. I te Oketopa 2018, i paahitia e te kamupene te tiwhikete hinonga hangarau-teitei ā-motu, ā, i noho hei hinonga hangarau-teitei taumata-motu. I te Oketopa 2023, kua whiwhi te kamupene i te katoa o ngā patene 18 (tae atu ki te 2 patene hanga hou me te 16 patene tauira whaipainga), ā, kei te tono inaianei mō te 1 patene hanga hou.
