Ihe mmetụta elektrọd Fluoride Ion CS6510C Rs485

Nkọwa Dị Mkpirikpi:

Fluoride Ion-Selective Electrode (ISE) bụ ihe mmetụta electrochemical pụrụ iche ma dịkwa mma nke e mere maka nha potentiometric kpọmkwem nke ọrụ fluoride ion (F⁻) na mmiri mmiri. A maara ya maka nhọrọ pụrụ iche ya ma bụrụkwa ngwa ọrụ ọkọlọtọ na kemistri nyocha, nlekota gburugburu ebe obibi, njikwa usoro ụlọ ọrụ mmepụta ihe, na ahụike ọha, ọkachasị maka ime ka fluoride dị mma na mmiri ọṅụṅụ.
Isi ihe dị na elektrọd a bụ akpụkpọ ahụ siri ike nke nwere otu kristal nke lanthanum fluoride (LaF₃). Mgbe ọ na-emetụ ihe ngwọta aka, ion fluoride sitere na ihe nlele ahụ na-emekọrịta ihe na lattice kristal, na-emepụta ike eletriki a na-atụ anya ya n'ofe akpụkpọ ahụ. Ike a, nke a tụrụ na elektrọd ntụaka dị n'ime, dabara na ọrụ ion fluoride dịka nha Nernst si dị. Ihe dị mkpa maka nha ziri ezi bụ ịgbakwunye Nguzozi Ike Ionic (TISAB). Ngwọta a na-arụ ọrụ atọ dị mkpa: ọ na-ejigide pH na-adịgide adịgide (na-abụkarị ihe dị ka 5-6), na-edozi ndabere ionic iji gbochie mmetụta matrix, ma nwee ihe ndị na-eme ka mgbagwoju anya tọhapụ ion fluoride nke cations na-egbochi dị ka aluminum (Al³⁺) ma ọ bụ iron (Fe³⁺) jikọtara.
