Izinzwa ze-CS6510C Fluoride Ion Electrode Rs485

Incazelo emfushane:

I-Fluoride Ion-Selective Electrode (ISE) iyinzwa ye-electrochemical ekhethekile kakhulu futhi ethembekile eyenzelwe ukulinganisa ngqo i-potentiometric yomsebenzi we-fluoride ion (F⁻) ezixazululweni zamanzi. Iyaziwa ngokukhetha kwayo okuyingqayizivele futhi iyithuluzi elijwayelekile kumakhemikhali okuhlaziya, ukuqapha imvelo, ukulawulwa kwezinqubo zezimboni, kanye nempilo yomphakathi, ikakhulukazi ekwenzeni ngcono i-fluoridation emanzini okuphuza.
Ingqikithi ye-electrode iyi-membrane yokuzwa yesimo esiqinile evame ukwakhiwa yikristalu eyodwa ye-lanthanum fluoride (LaF₃). Uma ixhumana nesisombululo, ama-ion e-fluoride avela kusampula asebenzisana ne-crystal lattice, ekhiqiza amandla kagesi alinganiswayo kulo lonke ulwelwesi. Leli khono, elilinganiswa ne-electrode yokubhekisela yangaphakathi, lilingana ngokwe-logarithmic nomsebenzi we-ion ye-fluoride ngokusho kwe-Nernst equation. Imfuneko ebalulekile yokulinganisa okunembile ukwengeza i-Total Ionic Strength Adjustment Buffer (TISAB). Lesi sixazululo senza imisebenzi emithathu ebalulekile: sigcina i-pH engaguquki (ngokuvamile cishe i-5-6), silungisa isizinda se-ionic ukuvimbela imiphumela ye-matrix, futhi siqukethe ama-complexing agents okukhulula ama-ion e-fluoride aboshwe yi-cations ephazamisayo njenge-aluminium (Al³⁺) noma insimbi (Fe³⁺).
