Firikwensin Ion na Fluoride CS6510

Takaitaccen Bayani:

Na'urar lantarki mai zaɓin fluoride ion wani lantarki ne mai zaɓe wanda ke da saurin amsawa ga yawan sinadarin fluoride ion, wanda aka fi sani da na'urar lantarki mai suna lanthanum fluoride electrode.
Lanthanum fluoride electrode wani firikwensin ne da aka yi da lu'ulu'u ɗaya mai siffar lanthanum fluoride wanda aka haɗa shi da yuropium fluoride tare da ramukan lattice a matsayin babban kayan aiki. Wannan fim ɗin lu'ulu'u yana da halayen ƙaurawar ion na fluoride a cikin ramukan lattice.
Saboda haka, yana da kyakkyawan yanayin watsa ion. Ta amfani da wannan membrane na lu'ulu'u, ana iya yin electrode na ion na fluoride ta hanyar raba mafita biyu na ion na fluoride. Na'urar firikwensin ion na fluoride tana da ma'aunin zaɓi na 1.
Kuma kusan babu wani zaɓi na sauran ions a cikin maganin. Ion ɗin da ke da tsangwama mai ƙarfi shine OH-, wanda zai yi aiki da lanthanum fluoride kuma ya shafi tantance ions na fluoride. Duk da haka, ana iya daidaita shi don tantance samfurin pH <7 don guje wa wannan tsangwama.
