Ion selective electrode i sensor ye electrochemical iyo simba rayo rinoenderana nelogarithm yeion chiitiko mune imwe mhinduro.Iyo imhando ye electrochemical sensor inoshandisa membrane kugona kuona ion chiitiko kana kusungirira mumhinduro.Iyo ndeye membrane electrode,avo core component ndiyo inonzwa membrane ye electrode.Ion selective electrode method ibazi re potentiometric analysis.Inowanzoshandiswa mune yakananga potentiometric nzira uye potentiometric titration.Iyo yekushandisa modhi inoratidzwa mukati zvayo wide application range.Uyezve, it anogona kuyera kusanganiswa kweiyoni chaiyo mumhinduro. Mukuwedzera, it haina kukanganiswa ne thecolor uye turbidity nezvimwe zvinhu zve reagent.
Kuyera maitiro eion selective electrode
Kana maion akayerwa mumushonga we electrode anobata electrode, ion migration inoitika muaquifer yeion selective electrode membrane matrix.Pane mukana wekuchinja kwechaji yeion inotama, iyo inoshandura kugona pakati pe membrane kumeso.Nokudaro, mutsauko unogona kuitika unogadzirwa pakati pe electrode yekuyera uye electrode yereferensi.Zvakanakira kuti mutsauko unogona kuburitswa pakati peion selective electrode uye maion achayerwa mumhinduro anofanira kuenderana neNernst equation, inova.
E=E0+ log10a(x)
E: Yakayerwa kugona
E0: Yakajairika electrode kugona (nguva dzose)
R: Gasi nguva dzose
T: Tembiricha
Z: Ionic valence
F: Faraday nguva dzose
a(x): ion chiitiko
Zvinogona kuonekwa kuti kuyerwa kwe electrode kugona kunoenzana nelogarithm yebasa re "X" ions.Kana iyo coefficient yebasa ikaramba iripo, iyo electrode inogona kuenzanawo nelogarithm yeion concentration (C).Nenzira iyi, chiitiko kana kusangana kweion mune mhinduro inogona kuwanikwa.
