Dab tsi yog qhov txawv ntawm Edta thiab Sodium Citrate?

Qhov sib txawv tseem ceeb ntawm EDTA thiab sodium citrate yog tias EDTA muaj txiaj ntsig zoo rau kev kuaj ntshav vim tias nws khaws cov qe ntshav zoo dua li lwm cov tshuaj zoo sib xws, thaum sodium citrate muaj txiaj ntsig zoo li tus neeg saib xyuas coagulation vim cov yam ntxwv V thiab VIII ruaj khov hauv cov khoom no.

EDTA (Ethylenediaminetetraacetic Acid) yog dab tsi?

EDTA los yog ethylenediaminetetraacetic acid yog ib qho aminopolycarboxylic acid uas muaj cov tshuaj formula [CH2N(CH2CO2H)2]2.Nws zoo nkaus li dawb, dej-soluble khoom uas siv dav hauv kev khi rau hlau thiab calcium ions.Cov tshuaj no tuaj yeem khi nrog cov ions ntawm rau lub ntsiab lus, uas ua rau nws paub tias yog tus hniav loj (hexadentate) chelating tus neeg sawv cev.Nws tuaj yeem muaj ntau hom EDTA, feem ntau disodium EDTA.

Kev lag luam, EDTA yog qhov tseem ceeb ua tus neeg sawv cev rau sequester hlau ions hauv cov kev daws teeb meem aqueous.Tsis tas li ntawd, nws tuaj yeem tiv thaiv cov hlau ion impurities los ntawm kev hloov cov xim ntawm dyes hauv kev lag luam textile.Tsis tas li ntawd, nws muaj txiaj ntsig zoo hauv kev sib cais ntawm lanthanide hlau los ntawm ion-pauv chromatography.Hauv kev lag luam tshuaj, EDTA tuaj yeem siv los kho cov tshuaj mercury thiab txhuas lom vim nws muaj peev xwm khi hlau ions thiab pab cais lawv.Ib yam li ntawd, nws tseem ceeb heev hauv kev txheeb xyuas ntshav.EDTA tseem tuaj yeem siv los ua cov khoom siv hauv cov khoom tu tus kheej xws li tshuaj zawv plaub hau, tshuaj ntxuav tes, thiab lwm yam, ua tus neeg sawv cev sequestering.

Sodium Citrate yog dab tsi?

Sodium citrate yog ib qho inorganic compound uas muaj sodium cations thiab citrate anions hauv qhov sib txawv.Muaj peb yam loj ntawm sodium citrate molecules: monosodium citrate, disodium citrate, thiab trisodium citrate molecule.Sib sau ua ke, peb cov ntsev no paub los ntawm tus lej E 331. Txawm li cas los xij, feem ntau daim ntawv yog trisodium citrate ntsev.

Trisodium citrate muaj cov tshuaj formula Na3C6H5O7.Feem ntau, qhov sib xyaw no feem ntau hu ua sodium citrate vim tias nws yog daim ntawv ntau tshaj ntawm sodium citrate ntsev.Cov tshuaj no muaj ib tug zoo li saline, me ntsis tart tsw.Tsis tas li ntawd, qhov sib xyaw no yog qhov yooj yim me ntsis, thiab peb tuaj yeem siv nws los ua cov kev daws teeb meem nrog rau citric acid.Cov tshuaj no zoo li cov hmoov dawb crystalline hmoov.Qhov tseem ceeb, sodium citrate yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li cov khoom noj additive, raws li ib tug flavoring los yog raws li ib tug preservative.
