ISE Sensor Calcium Ion Water Hardness Electrode CS6518A Calcium Ion Electrode

Tsananguro pfupi:

Kuomarara (Calcium Ion) Selective Electrode inyanzvi yekuongorora yakagadzirwa kuti ikwanise kuyera nekukurumidza uye zvakananga calcium ion (Ca²⁺) mu aqueous solutions. Kunyange zvazvo ichiwanzonzi "hardness" electrode, inonyanya kuyera free calcium ions, iyo inonyanya kukonzera kuomarara kwemvura. Inoshandiswa zvakanyanya mukutarisa nharaunda, kugadzirisa mvura mumaindasitiri (semuenzaniso, boiler uye cooling systems), kugadzira zvinwiwa, uye kurima gungwa, uko kudzora calcium kwakanyatsokosha pakushanda zvakanaka kwemaitiro, kudzivirira kukura kwemidziyo, uye hutano hwezvinhu zvipenyu.
Sensor inowanzo shandisa membrane yemvura kana yepolymer ine ionophore yakasarudzwa, senge ETH 1001 kana mamwe macompounds eproprietary, ayo anonyanya kuomarara necalcium ions. Kubatana uku kunogadzira mutsauko unogona kuitika mumembrane iyi kana tichienzanisa ne electrode yemukati. Voltage yakayerwa inotevera Nernst equation, ichipa mhinduro ye logarithmic kune calcium ion activity mukati mehuwandu hwakawanda hwe concentration (kazhinji kubva pa10⁻⁵ kusvika 1 M). Shanduro dzemazuva ano dzakasimba, dzinowanzo kuve nemagadzirirwo e solid-state akakodzera kuongororwa kwerabhoritari uye kuongororwa kwemaitiro epamhepo nguva dzose.
Chinhu chikuru che electrode iyi kugona kwayo kuita zviyero panguva chaiyo pasina wet chemistry inotora nguva, senge complememetric titrations. Zvisinei, kuyera nekungwarira uye kuenzanisa sample kwakakosha. Simba re ionic uye pH yemasamples zvinowanzo gadziriswa uchishandisa special ionic strength adjuster/buffer kuti pH ne mask interferens ions zvakaita se magnesium (Mg²⁺), izvo zvinogona kukanganisa kuverenga mune mamwe magadzirirwo. Kana yakachengetedzwa zvakanaka uye yakaongororwa, calcium ion-selective electrode inopa nzira yakavimbika, inoshanda, uye inodhura yekudzora kuomarara uye kuongorora calcium mumashandisirwo akasiyana-siyana.
