Dab tsi yog qhov sib txawv ntawm edta thiab sodium citrate?

Tus yuam sij sib txawv ntawm edta thiab cov citrium yog qhov tseem ceeb rau kev ntsuas cov ntshav zoo dua li lwm cov neeg sawv cev sib txawv ntawm V thiab VIII tau ruaj khov nyob hauv cov khoom no.

Dab tsi yog Edta (EthylenedIninetetraiacetic acid)?

Edta lossis EthylenedInAretRAACETS Acid yog aminopolycarboxylic acid muaj tshuaj lom neeg [Ch2n (ch2co2h) 2] 2. Nws zoo li yog dawb, dej-soluble khoom uas tau siv dav hauv kev khi rau cov hlau thiab calcium. Cov tshuaj no tuaj yeem khi nrog cov ions ntawm rau cov ntsiab lus, uas ua rau nws paub tias yog qhov loj-txhuam hniav (hexadentate) chelating tus neeg sawv cev. Nws tuaj yeem sib txawv cov ntaub ntawv ntawm EDTA, feem ntau feem ntau disodium edta.

Kev lag luam tsis muaj txiaj ntsig zoo, Edta siv tau raws li tus neeg sawv cev sib npaug rau cov kab ke sib dhos rau cov kev daws teeb meem aqueous. Ntxiv mus, nws tuaj yeem tiv thaiv cov ion impurities los ntawm kev kho cov xim ntawm cov dyes hauv kev lag luam textile. Tsis tas li ntawd, nws yog qhov muaj txiaj ntsig nyob rau hauv kev sib cais ntawm Lanthanide Metals los ntawm ion-txauv cov chromatography. Hauv thaj chaw ntawm cov tshuaj, EDTA tuaj yeem siv rau kev kho cov mercury thiab taug txhuas vim nws muaj peev xwm khi hlau ions thiab pab sib cais. Ib yam li ntawd, nws yog qhov tseem ceeb heev nyob rau hauv kev soj ntsuam ntawm cov ntshav. Edta tseem tuaj yeem siv los ua cov khoom muaj nyob rau hauv cov khoom lag luam saib xyuas xws li zawv plaub hau, ntxuav, thiab lwm yam.

Dab tsi yog sodium citrate?

Sodium citrate yog ib qho inorganic compound muaj cov sodium cations thiab citrate actions hauv cov sib piv. Muaj peb hom loj ntawm cov sodium citrate Molecules: Monosodium citrate, Idodium citrate, thiab trisodium citrate molecule. Suav sau, cov ntsev no tau paub los ntawm tus lej 331. Txawm li cas los xij, cov qauv feem ntau yog trisodium citrate ntsev.

Trisodium citrate muaj tshuaj lom neeg cov mis na3c6h55o7. Feem ntau, cov compound no feem ntau yog hu ua cov sodium citrate vim tias nws yog cov ntawv ntau tshaj plaws ntawm cov ntsev citrate ntsev. Cov tshuaj no muaj cov kua qab ntsev-nyiam, tart tsw me. Tsis tas li ntawd, cov ntais ntawv no yog cov me me, thiab peb tuaj yeem siv nws los ua cov kev daws teeb meem nrog citric acid. Cov tshuaj no zoo li hmoov dawb huv. Chiefly, sodium citrate yog siv nyob rau hauv cov kev lag luam khoom noj ua zaub mov ntxiv, raws li ib qho tsw qab lossis ua cov tshuaj tiv thaiv.

Dab tsi yog qhov sib txawv ntawm edta thiab sodium citrate?

Edta lossis EthylenedInAretRAACETS Acid yog aminopolycarboxylic acid muaj tshuaj lom neeg [Ch2n (ch2co2h) 2] 2. Sodium citrate yog ib qho inorganic compound muaj cov sodium cations thiab citrate actions hauv cov sib piv. Tus yuam sij sib txawv ntawm edta thiab cov kua zaub uas muaj txiaj ntsig yog qhov muaj txiaj ntsig zoo dua li lwm cov neeg sawv cev sib txawv ntawm V thiab VIII tau ruaj khov nyob hauv cov khoom no.
