Electrode e kgethang Ion ke sensor ya electrochemical eo bokgoni ba yona bo lekanang le logarithm ya mosebetsi wa ion tharollong e itseng. Ke mofuta wa sensor ya electrochemical e sebedisang bokgoni ba membrane ho fumana mosebetsi wa ion kapa mahloriso tharollong. Ke ya electrode ya membrane,eo Karolo ea mantlha ke lera la kutlo la electrode. Mokhoa oa electrode o khethang li-ion ke lekala la tlhahlobo ea potentiometric. Hangata e sebelisoa mokhoeng o tobileng oa potentiometric le titration ea potentiometric. Mohlala oa thuso o khetholloa ho ke wmefuta e fapaneng ea ts'ebeliso ea ideHo feta moo, it e ka lekanya mahloriso a li-ion tse itseng ka har'a tharollo. Ho phaella moo, ket ha e angoe ke e'mala le lerōle le lintlha tse ling tsa sesebelisoa sa ho lokisa lintho.
Mokhoa oa ho lekanya oa electrode e khethang ion
Ha li-ion tse lekantsoeng ka har'a tharollo ea electrode li kopana le electrode, ho falla ha li-ion ho etsahala ka har'a aquifer ea matrix ea membrane ea electrode e khethiloeng ea ion. Ho na le monyetla oa phetoho ea tjhaja ea li-ion tse fallang, e leng se fetolang monyetla oa pakeng tsa bokaholimo ba lera. Kahoo, phapang ea monyetla oa ho hlaha pakeng tsa electrode e lekanyang le electrode ea referense. Ho loketse hore phapang ea monyetla oa ho hlaha pakeng tsa electrode e khethollang li-ion le li-ion tse lokelang ho lekanyetsoa ka har'a tharollo e lumellane le equation ea Nernst, e leng
E=E0+ log10a(x)
E: Bokgoni bo lekantsoeng
E0: Bokhoni bo tloaelehileng ba elektrode (bo sa fetoheng)
R: Phetoho ea khase
T: Mocheso
Z: Valence ea Ionic
F: Kamehla ea Faraday
a(x): mosebetsi oa ion
Ho ka bonoa hore bokgoni ba electrode bo lekantsoeng bo lekana le logarithm ya mosebetsi wa di-ion tsa "X". Ha coefficient ya mosebetsi e dula e tsitsitse, bokgoni ba electrode le bona bo lekana le logarithm ya mahloriso a di-ion (C). Ka tsela ena, mosebetsi kapa mahloriso a di-ion ka hara tharollo a ka fumanwa.
