Electrode e khethehileng ea ion
Ion selective electrode ke sensor ea electrochemical eo bokhoni ba eona bo lekanang le logarithm ea ts'ebetso ea ion tharollong e fanoeng. Ke mofuta oa sensor ea electrochemical e sebelisang bokhoni ba membrane ho tseba ts'ebetso ea ion kapa mahloriso a tharollo. Ke karolo ea membrane electrode,eo karolo ea mantlha ke lera la kutlo la electrode. Ion selective electrode method ke lekala la tlhahlobo ea potentiometric. Ka kakaretso e sebelisoa ka mokhoa o tobileng oa potentiometric le titration ea potentiometric. Mohlala oa lisebelisoa o tšoauoa ka eona wide app range. Ho feta moo, it e ka metha mokoloko oa li-ion tse itseng ka tharollong. Ho phaella moo, ket ha e amehe ke themmala le turbidity le lintlha tse ling tsa reagent.
Mokhoa oa ho lekanya oa electrode e khethang ea ion
Ha li-ion tse lekantsoeng ka tharollo ea electrode li kopana le electrode, ho falla ha ion ho etsahala ka har'a aquifer ea ion selective electrode membrane matrix. Ho na le monyetla oa phetoho ea tefiso ea li-ion tse fallang, tse fetolang bokhoni lipakeng tsa bokaholimo ba lera. Ka hona, phapang e ka bang teng e hlahisoa pakeng tsa electrode ea ho lekanya le electrode ea boitsebiso. Ho molemo hore phapang e ka bang teng lipakeng tsa electrode e khethang ea ion le li-ion tse lekantsoeng tharollong e lumellane le equation ea Nernst, e leng.
E=E0+ log10a(x)
E: Bokhoni bo lekantsoeng
E0: Monyetla o tloaelehileng oa li-electrode (kamehla)
R: Khase kamehla
T: Mocheso
Z: Valence ea Ionic
F: Faraday kamehla
a(x): ts'ebetso ea ion
Ho ka bonoa hore bokhoni bo lekantsoeng ba li-electrode bo lekana le logarithm ea ts'ebetso ea "X" ion. Ha coefficient ea ts'ebetso e lula e sa fetohe, matla a electrode a boetse a lekana le logarithm ea mahloriso a ion (C). Ka tsela ena, ts'ebetso kapa khatello ea li-ion tharollong e ka fumanoa.
