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

Tsananguro pfupi:

Fluoride Ion-Selective Electrode (ISE) inyanzvi yepamusoro uye yakavimbika ye electrochemical sensor yakagadzirirwa kuyera zvakananga potentiometric ye fluoride ion (F⁻) activity mu aqueous solutions. Inozivikanwa nekusarudza kwayo kwakasiyana uye chishandiso chakajairika mu analytical chemistry, Environmental Monitoring, Industrial Process Control, uye Public Health, kunyanya pakuvandudza fluoridation mumvura yekunwa.
Pakati peelectrode i membrane inonzwika sesolid-state inowanzo umbwa nekristaro imwe chete ye lanthanum fluoride (LaF₃). Kana yakabatana nemhinduro, maion e fluoride anobva mumuenzaniso anosangana ne crystal lattice, zvichigadzira simba remagetsi rinoyerwa mu membrane. Simba iri, rakayerwa ne internal reference electrode, rinoenderana ne logarithmically ne fluoride ion activity zvichienderana ne Nernst equation. Chinhu chakakosha chinodiwa pakuyera kwakarurama kuwedzera Total Ionic Strength Adjustment Buffer (TISAB). Mhinduro iyi inoita mabasa matatu akakosha: inochengetedza pH isingachinji (kazhinji inenge 5-6), inogadzirisa ionic background kudzivirira matrix effects, uye ine complexing agents dzinosunungura maion e fluoride akasungwa ne interruptible cations se aluminium (Al³⁺) kana iron (Fe³⁺).
Zvakanakira zvikuru zve fluoride electrode ndezvekuti inosarudza zvakanaka kupfuura mamwe maanion akajairika, ine simba rakakura (kazhinji kubva pa 10⁻⁶ M kusvika kune mhinduro dzakaguta), mhinduro inokurumidza, inogara kwenguva refu, uye mutengo wakaderera wekushanda. Inogonesa kuongororwa nekukurumidza pasina kugadzirira kwakaoma kwesampuro kana ma reagents e colorimetric. Ingave ichishandiswa mumamita anotakurika ekuyedza mumunda, ma laboratory benchtop analyzers, kana kuti yakabatanidzwa mumasisitimu ekutarisa online, fluoride ISE inoramba iri nzira yakasarudzwa yekuenzanisa fluoride nemazvo, zvinobudirira, uye zvinoenderera mberi.
