Li-sensor tsa Electrode tsa Fluoride Ion tsa CS6510C Rs485

Tlhaloso e Khutšoanyane:

Electrode e Khethang Ion ea Fluoride (ISE) ke sensor ea electrochemical e ikhethang haholo le e tšepahalang e etselitsoeng ho lekanya ka kotloloho potentiometric ea ts'ebetso ea fluoride ion (F⁻) litharollong tsa metsi. E tsebahala ka khetho ea eona e ikhethang 'me ke sesebelisoa se tloaelehileng k'hemistri ea tlhahlobo, tlhokomelo ea tikoloho, taolo ea ts'ebetso ea indasteri le bophelo bo botle ba sechaba, haholo-holo bakeng sa ho ntlafatsa fluoridation metsing a nooang.
Karolo e ka sehloohong ea electrode ke lera la ho lemoha boemo bo tiileng leo hangata le entsoeng ka kristale e le 'ngoe ea lanthanum fluoride (LaF₃). Ha e kopana le tharollo, li-ion tsa fluoride tse tsoang sampole li sebelisana le lattice ea kristale, li hlahisa bokhoni ba motlakase bo ka lekanngoang ho pholletsa le lera. Bokhoni bona, bo lekanngoang khahlanong le electrode ea referense ea ka hare, bo lekana ka logarithmic le ts'ebetso ea ion ea fluoride ho latela equation ea Nernst. Tlhokahalo ea bohlokoa bakeng sa tekanyo e nepahetseng ke ho eketsoa ha Total Ionic Strength Adjustment Buffer (TISAB). Tharollo ena e sebeletsa mesebetsi e meraro ea bohlokoa: e boloka pH e sa fetoheng (hangata e ka bang 5-6), e lokisa bokamorao ba ionic ho thibela litlamorao tsa matrix, 'me e na le li-agent tse rarahaneng ho lokolla li-ion tsa fluoride tse tlamiloeng ke li-cation tse sitisang joalo ka aluminium (Al³⁺) kapa tšepe (Fe³⁺).
