Ukuqina kwe-CS6710A Fluoride Ion Electrod Online Digital F-Cl- Ca2+ NO3- NH4+ K+

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⁺).
Izinzuzo ezibalulekile ze-fluoride electrode ukukhetha kwayo okuhle kakhulu kunezinye i-anion ezivamile, ububanzi obuguquguqukayo (ngokuvamile kusukela ku-10⁻⁶ M kuya kuzixazululo ezigcwele), impendulo esheshayo, isikhathi eside sokuphila, kanye nezindleko zokusebenza eziphansi. Ivumela ukuhlaziywa okusheshayo ngaphandle kokulungiswa kwesampula okuyinkimbinkimbi noma ama-reagent e-colorimetric. Kungakhathaliseki ukuthi isetshenziswa kumamitha aphathekayo okuhlolwa kwensimu, abahlaziyi be-benchtop belabhoratri, noma ihlanganiswe ezinhlelweni zokuqapha eziku-inthanethi, i-fluoride ISE isalokhu iyindlela yokukhetha yokulinganisa i-fluoride okunembile, okusebenzayo, nokuqhubekayo.
