I-CS6710A Fluoride Ion Electrod kwi-Intanethi yeDijithali F-Cl- Ca2+ NO3- NH4+ K+ Ubulukhuni

Inkcazo emfutshane:

I-Fluoride Ion-Selective Electrode (ISE) sisiva-sensor se-electrochemical esikhethekileyo nesithembekileyo esenzelwe ukulinganisa ngokuthe ngqo umsebenzi we-fluoride ion (F⁻) kwizisombululo zamanzi. Iyaziwa ngokukhetha kwayo okugqwesileyo kwaye sisixhobo esiqhelekileyo kwikhemistri yohlalutyo, ukujonga okusingqongileyo, ulawulo lweenkqubo zoshishino, kunye nempilo yoluntu, ngakumbi ekuphuculeni i-fluoridation emanzini okusela.
Ingundoqo ye-electrode yi-membrane ye-solid-state sensing edla ngokwenziwa yikristale enye ye-lanthanum fluoride (LaF₃). Xa idibana nesisombululo, ii-ion ze-fluoride ezivela kwisampuli zidibana ne-crystal lattice, zivelisa amandla ombane anokulinganiswa kuyo yonke i-membrane. Le potential, elinganiswa ne-electrode yesalathiso sangaphakathi, ilingana ne-logarithmically nomsebenzi we-ion ye-fluoride ngokwe-Nernst equation. Imfuneko ebalulekileyo yokulinganisa ngokuchanekileyo kukongezwa kwe-Total Ionic Strength Adjustment Buffer (TISAB). Esi sisombululo senza imisebenzi emithathu ebalulekileyo: sigcina i-pH engaguqukiyo (ngesiqhelo malunga ne-5-6), silungisa imvelaphi ye-ionic ukuthintela iziphumo ze-matrix, kwaye siqulathe ii-agents ezidibanisa ukukhulula ii-ion ze-fluoride ezibotshelelwe zii-cations eziphazamisayo ezifana ne-aluminium (Al³⁺) okanye i-iron (Fe³⁺).
Iingenelo eziphambili ze-fluoride electrode kukukhetha kwayo okuhle kakhulu kunezinye ii-anions eziqhelekileyo, uluhlu olubanzi lwe-dynamic (ngesiqhelo ukusuka kwi-10⁻⁶ M ukuya kwizisombululo ezigcweleyo), impendulo ekhawulezayo, ubomi obude, kunye neendleko eziphantsi zokusebenza. Ivumela uhlalutyo olukhawulezileyo ngaphandle kokulungiswa kwesampulu enzima okanye ii-reagents zemibala. Nokuba isetyenziswa kwiimitha eziphathwayo zovavanyo lwasentsimini, ii-laboratory benchtop analyzers, okanye idityaniswe kwiinkqubo zokubeka esweni kwi-intanethi, i-fluoride ISE ihlala iyindlela ekhethwayo yokulinganisa i-fluoride ngokuchanekileyo, ngokufanelekileyo, nangokuqhubekayo.
