CS6710A Hikohiko Ā-pūhaumāota Ipurangi Mamati F- Cl- Ca2+ NO3- NH4+ K+ Mārō

Whakaahuatanga Poto:

Ko te Hikohiko Whiriwhiri-Ā-Irahiko (ISE) he pūoko hiko matū tino motuhake, pono hoki i hangaia mō te ine tika i te kaha o te ā-irahiko fluoride (F⁻) i roto i ngā otinga wai. He rongonui mō tōna tino whiriwhiringa, ā, he taputapu paerewa i roto i te matū tātari, te aroturuki taiao, te whakahaere tukanga ahumahi, me te hauora tūmatanui, inā koa mō te arotau i te whakapūhaumāota i roto i te wai inu.
Ko te pūtake o te irahiko he kiriuhi pūoko totoka e titoa ana i te tioata kotahi o te lanthanum fluoride (LaF₃). Ina pā atu ki tētahi otinga, ka taunekeneke ngā iona fluoride mai i te tauira ki te whatanga tioata, ka puta he pūmanawa hiko ka taea te ine puta noa i te kiriuhi. Ko tēnei pūmanawa, e inehia ana ki tētahi irahiko tohutoro ā-roto, he rite tonu ki te mahi iona fluoride e ai ki te whārite Nernst. Ko tētahi whakaritenga nui mō te ine tika ko te tāpiri i te Pūwero Whakatikatika Kaha Ionic Katoa (TISAB). E toru ngā mahi nui a tēnei otinga: ka pupuri i te pH pumau (i te nuinga o te wā tata ki te 5-6), ka whakatika i te papamuri ionic hei ārai i ngā pānga matrix, ā, kei roto hoki ngā kaihoko matatini hei tuku i ngā iona fluoride e herea ana e ngā kationa pokanoa pērā i te konumohe (Al³⁺) te rino rānei (Fe³⁺).
Ko ngā painga matua o te irahiko fluoride ko tōna tino whiriwhiringa i runga i ētahi atu anion noa, te whānuitanga hihiri whānui (mai i te 10⁻⁶ M ki ngā otinga kua mātotoru), te urupare tere, te roa o te ora, me te iti o te utu whakahaere. Ka taea te tātari tere me te kore e hiahiatia he whakarite tauira uaua, he tauhohenga tae rānei. Ahakoa e whakamahia ana i roto i ngā mita kawe mō te whakamātautau mara, i ngā tātaritanga papa taiwhanga, i whakauruhia rānei ki roto i ngā pūnaha aroturuki ipurangi, ko te fluoride ISE tonu te tikanga whiriwhiri mō te ine fluoride tika, whai hua, me te haere tonu.
