RS485 Isensa ya Ioni ya Fluoride CS6510A Ioni ya Fluoride

Ibisobanuro bigufi:

Electrode ya Fluoride Ion-Selective Ion (ISE) ni sensor yihariye kandi yizewe ya electrochemical yagenewe gupima imikorere ya fluoride ion (F⁻) mu bisubizo by'amazi. Izwiho guhitamo neza cyane kandi ni igikoresho gisanzwe mu buhanga bwo gusesengura, kugenzura ibidukikije, kugenzura ibikorwa by'inganda, no kubungabunga ubuzima rusange, cyane cyane mu kunoza fluoride mu mazi yo kunywa.
Imbere muri electrode ni urusobe rw’ibintu bifatika rusanzwe rugizwe na kristu imwe ya lanthanum fluoride (LaF₃). Iyo ihuye n’umuti, iyoni za fluoride ziva mu gipimo zikorana na lattice ya kristu, bigatuma habaho ubushobozi bw’amashanyarazi bupimwe ku rusobe rw’umuti. Ubu bushobozi, bupimwe ugereranije na electrode y’imbere, bungana na logarithmically n’ibikorwa bya iyoni za fluoride hakurikijwe ikigereranyo cya Nernst. Ikintu cy’ingenzi gisabwa kugira ngo hapimwe neza ni ukongeraho Total Ionic Strength Adjustment Buffer (TISAB). Iki gisubizo gikora imirimo itatu y’ingenzi: gikomeza pH ihoraho (ubusanzwe hafi 5-6), gikemura inyuma ya iyoni kugira ngo hirindwe ingaruka za matrix, kandi kikagira ibintu bivangavanze byo kurekura iyoni za fluoride ziboshywe n’ibintu bibangamira nka aluminiyumu (Al³⁺) cyangwa icyuma (Fe³⁺).
Ibyiza by'ingenzi bya electrode ya fluoride ni uburyo ihitamo neza kurusha izindi anions zisanzwe, uburyo bwagutse bwo guhindura imiterere y'ibinyabutabire (ubusanzwe kuva kuri 10⁻⁶ M kugeza ku bisubizo byuzuye), uburyo bwo gusubiza vuba, igihe kirekire, n'igiciro gito cyo gukora. Ituma isesengura ryihuse ritabanje gutegura ingero zigoye cyangwa reagents zo mu bwoko bwa colorimetric. Byaba bikoreshwa mu bipimo byo mu murima, mu gusesengura imiterere y'ibinyabutabire, cyangwa bishyizwe muri sisitemu zo kugenzura kuri interineti, fluoride ISE ikomeje kuba uburyo bwiza bwo gupima fluoride neza, neza kandi buhoraho.
