Ua ntej, nws yog fluorine thiab fluoride thiab tsis yog hmoov nplej thiab hmoov nplej. Kev sau tsis raug yog ib txwm muaj, tab sis tus "u" los ua ntej "o " hauv ob qho . Fluorine yog ib qho tshuaj lom neeg. … Cov fluorine anion, F-, los yog ib qho ntawm cov tebchaw uas muaj cov anion yog hu ua fluorides.
Vim li cas nws thiaj li muaj fluoride thiab tsis muaj fluorine?
Fluoride yog tshuaj muaj feem xyuam nrog fluorine, tab sis lawv tsis zoo ib yam. Fluoride yog ib qho tshuaj sib txawv. Fluoride yog tsim los ntawm cov ntsev uas tsim thaum fluorine ua ke nrog cov zaub mov hauv av lossis pob zeb. Fluoride feem ntau yog qhov ruaj khov thiab tsis ua haujlwm zoo, tsis zoo li nws cov tshuaj fluorine.
Puas muaj fluoride hauv tshuaj txhuam hniav?
Tus nqi ntawm cov tshuaj fluoride hauv cov tshuaj txhuam hniav tuaj yeem pom ntawm sab ntawm lub rajthiab ntsuas hauv qhov chaw ib lab (ppm). Cov tshuaj txhuam hniav uas muaj 1, 350 txog 1, 500ppm fluoride yog qhov zoo tshaj plaws.
