Ma electrode a PH amasiyana m'njira zosiyanasiyana;kuyambira nsonga mawonekedwe, mphambano, zakuthupi ndi kudzaza.Kusiyana kwakukulu ndikuti electrode ili ndi njira imodzi kapena iwiri.
Kodi ma electrode a pH amagwira ntchito bwanji?
Maelekitirodi ophatikizika a pH amagwira ntchito pokhala ndi theka la cell (AgCl yokutidwa ndi waya wa siliva) ndi theka la cell (Ag/AgCl reference electrode waya), zigawo ziwirizi ziyenera kulumikizidwa pamodzi kuti amalize kuzungulira kuti mita ipezeke. kuwerenga pH.Pomwe theka la cell limamva kusintha kwa pH ya yankho, theka la cell ndilokhazikika.Ma electrode amatha kukhala amadzimadzi kapena odzaza gel.Electrode yamadzimadzi imapanga mphambano yokhala ndi filimu yopyapyala yodzaza yankho kunsonga kwa kafukufukuyo.Nthawi zambiri amakhala ndi ntchito yapampu yokulolani kuti mupange mphambano yatsopano pakugwiritsa ntchito kulikonse.Amafunikira kuwonjezeredwa pafupipafupi koma amapereka magwiridwe antchito abwino kwambiri owonjezera moyo wawo wonse, kulondola komanso kuthamanga kwa kuyankha.Ngati kusamalidwa ndi mphambano yamadzimadzi kumakhala ndi moyo wamuyaya.Ma elekitirodi ena amagwiritsa ntchito gel electrolyte yomwe sifunikira kuwonjezeredwa ndi wogwiritsa ntchito.Izi zimawapangitsa kukhala njira yaulere yaulere koma imachepetsa moyo wa elekitirodi pafupifupi chaka chimodzi ngati itasungidwa bwino.
Double Junction - ma elekitirodi a pH awa ali ndi mlatho wowonjezera wamchere kuti aletse kuyanjana pakati pa njira yodzaza ma elekitirodi ndi chitsanzo chanu chomwe chingapangitse kuwonongeka kwa mphambano yamagetsi.Amayenera kuyesa zitsanzo zomwe zili ndi mapuloteni, zitsulo zolemera kapena sulfide
Single Junction - izi ndizomwe zimagwiritsidwa ntchito pazitsanzo zomwe sizingatseke mphambano.
Ndi mtundu wanji wa pH electrode womwe ndiyenera kugwiritsa ntchito?
Ngati chitsanzo chili ndi mapulotini, ma sulphite, heavy metals kapena TRIS ma buffers, electrolyte amatha kuchitapo kanthu ndi chitsanzocho ndikupanga madzi olimba omwe amatchinga podutsana ndi electrode ndikuyimitsa kugwira ntchito.Ichi ndi chimodzi mwa zifukwa zomwe zimayambitsa "electrode akufa" zomwe timaziwona nthawi ndi nthawi.
Pazitsanzozo mumafunika kulumikizana kawiri - izi zimapereka chitetezo chowonjezera ku izi, kuti mukhale ndi moyo wabwinoko kuchokera pa pH electrode.
