Chemxin tshuab ua kom qaug tau tus kabmob deflorination muaj peev xwm ua kom siab, thiab nws tsis yog mob toxic, tasteless, odorless, insoluble hauv dej thiab organic solvents.
Siv cov tshuaj fluoride tshem tawm hauv cheeb tsam high fluoride, cyclic alkanes defluorinating agent ntawm cov khoom xyaw alkylbenzene. Cov khoom no tuaj yeem siv tau rau dearsenification, wastewater decolorizing, deodorizing, etc.
Taw qhia
Activated alumina defluorinating tus neeg sawv cev yog xim dawb qhov sib npaug, qhov sib npaug particle loj, du nto, siab mechanical zog, hygroscopicity muaj zog, tsis tawg thiab inflate tom qab absorbing dej.
Fluorine yog ib lub cim kab uas tsim nyog rau tsiaj txhu thiab tib neeg. Cov neeg laus txhua hnub kom tsawg yuav tsum yog 2 ~ 3 mg, ntau dhau los lossis tsawg tsawg tuaj yeem ua rau muaj kab mob, yog li cov tshuaj tua kabmob tseem ceeb hauv cov dej haus. Alumina ua kom muaj zog, ua haujlwm zoo, ua haujlwm tsis zoo, ua haujlwm ntev, ua kom muaj kev kub ntxhov, muaj peev xwm ua kom zoo dua qub tom qab cov dej haus zoo nrog lub teb chaws tus qauv kev noj qab haus huv, yog li activated alumina yog ib qho ntawm cov khoom siv hauv dej tshuaj.
Activated alumina defluorinating agent muaj amphoteric adsorption zog, los ntawm regulating tus nqi paug aqueous kua, anions nyob rau hauv cov kua aqueous yuav kas tsev txawb. Cov khoom siv puas tsuaj zoo ib yam li ion exchanger, txhawm rau ua kom muaj peev xwm ua kom muaj siab, yuav tsum tau txo tus nqi paab, thaum tus nqi paab 5.5, nws yog qhov loj tshaj plaws ntawm cov tshuaj fluorine. Yuav kom ua tau raws li qhov yuav tsum ua kom zoo thiab tswj kev txhuam, PH qhov tseem ceeb yuav tsum yog acidic me ntsis. Ua rau alumina defluorination zoo ib yam li cov hloov pauv pauv, tiam sis cov xim ntawm cov tshuaj fluoride ion ntau dua li cov pob zeb txha tsev.
Tsawg me me qhov hnyav tuaj yeem ua rau thaj chaw deg, ua kom muaj kev sib txuas ntawm cov pob alumina thiab dej. Piv txwv li, feem ntau siv 1-3 hli, 0.4-1.2 hli, lawv cov cheeb tsam ntawm qhov chaw muaj feem ntau tshaj 320 m2 / g. Qhov chaw saum npoo av loj txhais tau hais tias muaj pes tsawg tus micropore, nws tuaj yeem ua kom muaj zog adsorption ntawm fluoride ion hauv dej. Thaum twg cov dej muaj txiaj ntsig thiab alkalinity tsawg dua, lub peev xwm ua kom nrov ntawm alumina muaj ntau dua, cov tshuaj fluoride absorption ntawm ib lub tshuab ntsuas roj yog 6400 gram, fluoride nqus tau ntau dua 4.0 mg / g, thiab tus nqi qis tshaj hluavtaws.
