CS6510 Fluoride Ion yoluvo

Inkcazelo emfutshane:

I-ion ye-fluoride ekhethiweyo ye-electrode yi-electrode ekhethiweyo enomdla kwi-concentration ye-ion ye-fluoride, eyona ixhaphakileyo yi-lanthanum fluoride electrode.
I-Lanthanum fluoride electrode yinzwa eyenziwe ngekristale enye ye-lanthanum fluoride efakwe i-europium fluoride enemingxuma yelattice njengeyona nto iphambili. Le filimu ye-crystal ineempawu zokufuduka kwe-fluoride ion kwimingxuma ye-lattice.
Ke ngoko, ine-ion conductivity entle kakhulu. Ukusebenzisa le crystal membrane, i-electrode ye-ion ye-fluoride inokwenziwa ngokwahlula izisombululo ze-ion ze-fluoride ezimbini. I-ion sensor ye-fluoride ine-coefficient yokukhetha ye-1.
Kwaye akukho phantse ukhetho lwezinye ion kwisisombululo. I-ion kuphela enokuphazamiseka okunamandla yi-OH-, eya kusabela kunye ne-lanthanum fluoride kwaye ichaphazele ukuzimisela kwe-ion fluoride. Nangona kunjalo, inokulungelelaniswa ukumisela isampuli pH <7 ukuphepha oku kuphazamiseka.
