Hauv peb lub neej txhua hnub, peb feem ntau hnov txog ntau yam tshuaj lom neeg uas ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Ib qho ntawm cov tshuaj no yog EDTA-Zn, uas siv dav hauv kev ua liaj ua teb, kev lag luam zaub mov, kev lag luam tshuaj thiab cov khoom siv tshuaj txhua hnub.EDTA-Znnrog tus lej CAS 14025-21-9 yog lub npe luv rau ethylenediaminetetraacetic acid zinc sodium ntsev. Nws yog ib hom chelated compound, uas txhais tau tias nws yog tsim los ntawm kev sib xyaw zinc ions nrog EDTA.
Ⅰ. Cov khoom yooj yim
EDTA-Zn feem ntau zoo li cov hmoov dawb lossis dawb tawm. Nws tsis muaj ntxhiab tsw thiab yooj yim yaj hauv dej. Thaum yaj hauv dej, nws tsim cov kua pob tshab, tab sis nws tsis yaj hauv cov kuab tshuaj organic xws li ethanol thiab ether. Ethylenediaminetetraacetic acid zinc sodium ntsev muaj kev ruaj khov tshuaj zoo. Nws tuaj yeem tiv taus cov kua qaub tsis muaj zog thiab cov alkali tsis muaj zog, thiab tuaj yeem tiv taus qhov kub nruab nrab yam tsis yooj yim lwj. Nws tus nqi pH feem ntau yog nruab nrab ntawm 4.0 thiab 6.0, uas ua rau nws haum rau ntau qhov chaw sib txawv. Cov ntsiab lus zinc hauvEDTA-Zn nrog CAS 14025-21-9feem ntau yog nruab nrab ntawm 14.5% thiab 15.5%, uas yog ib qho tseem ceeb uas ua kom nws siv tau zoo.
Ⅱ. Cov txheej txheem npaj
Kev npaj EDTA-Zn tsis nyuaj heev. Muaj ntau txoj hauv kev los ua nws, thiab qhov feem ntau yog los ntawm kev sib xyaw tshuaj ntawm EDTA thiab cov ntsev zinc. Piv txwv li, peb tuaj yeem sib tov EDTA nrog zinc sulfate lossis zinc chloride, thiab tom qab ntawd ntxiv sodium hydroxide lossis sodium carbonate rau hauv qhov sib tov. Nyob rau hauv cov xwm txheej sib xyaw tsim nyog, cov tshuaj no yuav sib xyaw ua ke los ua EDTA-Zn. Thaum lub sijhawm npaj, peb yuav tsum tswj qhov kub thiab lub sijhawm sib xyaw kom ntseeg tau tias qhov zoo thiab huv ntawm cov khoom. Tag nrho cov txheej txheem sib xyaw muaj kev nyab xeeb thiab tsis tsim cov tshuaj lom neeg, tsuav yog peb ua raws li cov kauj ruam ua haujlwm raug.
Ⅲ. Cov kev siv tseem ceeb
EDTA-Znmuaj ntau yam kev siv, thiab kev ua liaj ua teb yog ib qho ntawm nws cov teb siv tseem ceeb. Zinc yog ib qho tseem ceeb rau kev loj hlob ntawm cov nroj tsuag. Nws pab cov nroj tsuag txhawb kev ua haujlwm ntawm enzyme, tswj kev nqus cov as-ham thiab txhim kho kev tiv thaiv kev ntxhov siab. Yog tias cov nroj tsuag tsis muaj zinc, lawv txoj kev loj hlob yuav qeeb, lawv cov nplooj yuav me thiab daj, thiab lawv cov txiv hmab txiv ntoo zoo yuav txo qis. EDTA-Zn tuaj yeem daws qhov teeb meem no tau zoo. Nws tuaj yeem siv ua chiv zinc, uas cov nroj tsuag yooj yim nqus tau. Piv nrog rau lwm cov chiv zinc, EDTA-Zn ruaj khov dua, tshwj xeeb tshaj yog nyob rau hauv cov av acidic lossis alkaline qhov twg zinc tsis yooj yim nqus tau. Nws tuaj yeem siv rau hauv av lossis txau rau ntawm nplooj ntawm cov nroj tsuag. Piv txwv li, hauv cov teb mov lossis cov tsev cog khoom dib, txau cov tshuaj EDTA-Zn kom raug tuaj yeem txo cov tsos mob ntawm zinc tsis txaus thiab txhawb kev loj hlob ntawm cov nroj tsuag. Nws kuj tseem siv dav hauv kev cog qoob loo kom pub cov nroj tsuag zoo nkauj xws li paj noob hlis thiab chrysanthemums.
Ntxiv rau kev ua liaj ua teb, EDTA-Zn kuj tseem siv rau hauv kev lag luam khoom noj thiab tshuaj. Zinc yog ib qho khoom noj tseem ceeb rau tib neeg kev noj qab haus huv. Nws muaj feem cuam tshuam nrog tib neeg txoj kev loj hlob thiab kev txhim kho, kev ua haujlwm ntawm lub cev tiv thaiv kab mob thiab kev noj qab haus huv ntawm kev yug me nyuam. Ntau tus neeg, tshwj xeeb tshaj yog cov menyuam yaus thiab cov hluas, tej zaum yuav tsis muaj zinc vim yog kev noj zaub mov tsis sib npaug. EDTA-Zn tuaj yeem siv ua cov khoom noj khoom haus ntxiv rau zinc hauv zaub mov. Nws feem ntau ntxiv rau cov khoom noj mis nyuj, cov nplej zom, dej haus thiab lwm yam khoom noj. Vim tias EDTA-Zn ruaj khov thiab yooj yim rau tib neeg lub cev nqus tau, nws yog ib qho khoom noj khoom haus zinc uas siv ntau hauv kev lag luam khoom noj. Nws tsis hloov qhov saj lossis xim ntawm zaub mov, yog li nws tau txais dav los ntawm cov neeg tsim khoom noj thiab cov neeg siv khoom.
Tsis tas li ntawd,EDTA-Znkuj siv rau hauv cov khoom siv tshuaj txhua hnub. Piv txwv li, nws tuaj yeem ntxiv rau cov khoom siv saib xyuas tawv nqaij xws li tshuaj pleev thiab tshuaj pleev. Zinc muaj cov nyhuv so rau ntawm daim tawv nqaij thiab tuaj yeem pab tswj kev noj qab haus huv ntawm daim tawv nqaij. EDTA-Zn, ua ib qho chelated zinc, yog qhov tsis hnyav thiab tsis yooj yim rau khaus tawv nqaij, yog li nws haum rau ntau hom tawv nqaij. Nws kuj tseem siv tau rau hauv cov khoom saib xyuas plaub hau kom txhim kho cov plaub hau zoo thiab txo cov plaub hau poob los ntawm kev tsis txaus zinc.
Ⅳ. Cov ntawv ceeb toom kev nyab xeeb
Thaum siv EDTA-Zn, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb ntawm EDTA-Zn. Txawm hais tias EDTA-Zn muaj kev nyab xeeb rau tib neeg thiab cov nroj tsuag thaum siv rau hauv qhov ntau thiab tsawg, kev siv ntau dhau yuav ua rau muaj kev phiv. Piv txwv li, kev siv ntau dhau hauv kev ua liaj ua teb yuav ua rau muaj zinc ntau dhau hauv av, uas cuam tshuam rau kev loj hlob ntawm lwm cov nroj tsuag. Hauv kev lag luam zaub mov, kev ntxiv ntau dhau yuav ua rau zinc ntau dhau hauv lub cev tib neeg, ua rau muaj cov tsos mob xws li xeev siab thiab raws plab. Yog li ntawd, peb yuav tsum ua raws li cov koob tshuaj pom zoo thaum siv EDTA-Zn.
Thaum khaws cia, EDTA-Zn yuav tsum khaws cia rau qhov chaw txias, qhuav thiab muaj cua nkag zoo. Nws yuav tsum nyob deb ntawm tshav ntuj ncaj qha thiab kub heev kom tsis txhob lwj. Nws kuj tseem yuav tsum khaws cia cais ntawm lwm yam tshuaj lom neeg kom tiv thaiv kev ua xua tshuaj lom neeg. Tsis tas li ntawd, nws yuav tsum khaws cia kom deb ntawm cov menyuam yaus thiab tsiaj txhu kom tsis txhob noj tsis tau.
Xaus lus, EDTA-Zn yog ib qho tshuaj chelated uas siv tau dav hauv kev ua liaj ua teb, kev lag luam zaub mov, kev lag luam tshuaj thiab cov khoom siv tshuaj niaj hnub. Nws qhov ruaj khov zoo thiab yooj yim nqus ua rau nws yog ib qho tseem ceeb hauv ntau qhov chaw. Los ntawm kev nkag siab txog nws cov yam ntxwv thiab siv nws kom raug, peb tuaj yeem ua si tag nrho rau nws lub luag haujlwm thiab coj kev yooj yim rau peb lub neej thiab kev tsim khoom. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, qhov kev siv EDTA-Zn yuav raug nthuav dav ntxiv yav tom ntej.
Yog koj xav tauyuav EDTA-Zn, ntawm tag nrho cov neeg muag khoom, Unilong Kev Lag Luam yog ib lub tuam txhab txhim khu kev qha. Nws cov khoom tsis yog tsuas yog muag hauv tsev xwb tab sis kuj xa tawm txawv teb chaws. Nws tsis tsuas yog tuaj yeem ua kom zoo ntawm cov khoom, tab sis kuj lav qhov ruaj khov ntawm cov khoom.
