Hauv peb lub neej txhua hnub, peb feem ntau ntsib ntau yam khoom noj khoom haus ntxiv, cov ntaub ntawv lag luam thiab cov tshuaj kho mob uas peb yuav tsis paub txog. Ib qho ntawm lawv yogEDTA-Canrog tus lej cas 23411-34-9, uas luv rau calcium disodium ethylenediaminetetraacetate. Txawm hais tias nws lub npe zoo li nyuaj, nws ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw thiab muaj feem cuam tshuam nrog peb lub neej.
Ua ntej tshaj plaws, nws yog ib qho tsim nyog los piav qhia meej tias EDTA-Ca yog dab tsi. EDTA-Ca yog ib yam tshuaj lom neeg tsim, uas zoo li cov hmoov dawb ntws dawb thiab yooj yim yaj hauv dej. Nws cov qauv tshuaj tso cai rau nws khi nrog ntau yam hlau ions, ib yam khoom hu ua chelation. Lub peev xwm chelating no yog qhov laj thawj tseem ceeb vim li cas EDTA-Ca tuaj yeem siv dav hauv ntau qhov chaw. Tsis zoo li qee yam khoom zoo sib xws, EDTA-Ca muaj calcium, uas ua rau nws muaj kev nyab xeeb dua hauv kev siv thiab txo nws cov kev cuam tshuam rau tib neeg lub cev nqus cov zaub mov tseem ceeb. Nws muaj ntau lub npe ntxiv, xws li edetate calcium disodium thiab calcium disodium edetate, tab sis lawv txhua tus xa mus rau tib yam khoom.
Kev lag luam zaub mov yog ib qho ntawm cov teb tseem ceeb ntawm kev sivEDTA-Ca. Raws li cov khoom noj khoom haus ntxiv, nws feem ntau yog siv los ua cov tshuaj preservative, stabilizer thiab sequestrant los pab tswj qhov zoo thiab ntev lub txee lub neej ntawm cov khoom noj. Hauv ntau cov khoom noj ua tiav, cov hlau ions xws li hlau thiab tooj liab yuav ua rau muaj kev hloov pauv ntawm cov tshuaj oxidation, ua rau muaj kev hloov pauv ntawm cov xim, saj thiab kev ntxhib los mos, thiab txawm tias cov khoom noj puas tsuaj. EDTA-Ca tuaj yeem khi cov hlau ions no, tiv thaiv cov tshuaj oxidation, thiab yog li ua kom cov khoom noj nyob rau hauv lub xeev zoo rau lub sijhawm ntev dua.
Piv txwv li, hauv cov khoom noj hauv qab xws li cov clams hauv qab, nqaij ntses, cw thiab ntau yam taum, EDTA-Ca feem ntau ntxiv rau kom khaws cov xim qub ntawm cov khoom noj thiab tiv thaiv kom tsis txhob muaj xim thaum khaws cia. Hauv cov khoom noj pickled xws li pickled cabbage thiab cucumbers, nws tuaj yeem pab khaws cov xim, saj thiab cov qauv ntawm cov khoom noj, ua rau cov saj ruaj khov dua. Hauv cov dej haus xws li cov dej qab zib hauv qab thiab cov dej cawv distilled, EDTA-Ca tuaj yeem txhawb kev khaws cia saj thiab tswj qhov meej ntawm cov dej haus, zam kev nag los ntawm cov hlau ions. Nws kuj tseem siv rau hauv cov kua zaub xas lav, mayonnaise, kua ntses thiab lwm yam khoom noj ua cov tshuaj tiv thaiv kom tiv thaiv kev puas tsuaj.
Yuav tsum nco ntsoov tias kev siv EDTA-Ca hauv zaub mov raug tswj hwm nruj heev hauv ntau lub tebchaws. Muaj cov kev txwv meej meej rau qhov ntau ntxiv rau cov zaub mov sib txawv, uas suav ua cov tshuaj anhydrous thiab feem ntau ntsuas hauv ib feem ntawm ib lab (ppm). Piv txwv li, qhov ntau tshaj plaws ntawm EDTA-Ca ntxiv rau cov clams hauv cov kaus poom yog 340 ppm, thaum qhov ntawd ntxiv rau cov dej qab zib hauv cov kaus poom yog 33 ppm. Cov kev cai no ua kom ntseeg tau tias EDTA-Ca tuaj yeem ua nws lub luag haujlwm thaum tsis ua rau tib neeg muaj kev phom sij.
Ntxiv rau kev lag luam khoom noj khoom haus, EDTA-Ca kuj muaj cov ntawv thov tseem ceeb hauv kev kho mob. Nws siv ntau tshaj plaws yog kev kho mob hnyav, tshwj xeeb tshaj yog kev lom los ntawm cov hlau lead. Vim nws muaj peev xwm chelating muaj zog, EDTA-Ca tuaj yeem khi nrog cov hlau hnyav xws li hlau lead, mercury, cadmium thiab hlau hauv tib neeg lub cev, tsim cov tshuaj soluble uas tuaj yeem tawm los ntawm cov zis, yog li txo qhov kev puas tsuaj ntawm cov hlau hnyav rau lub cev. Nws tau pom zoo rau kev kho mob ntawm kev lom los ntawm cov hlau lead hauv cov neeg laus thiab cov menyuam yaus hauv ntau lub tebchaws, thiab muaj txiaj ntsig zoo dua li qee cov neeg sawv cev chelating.
Tsis tas li ntawd,EDTA-Cakuj siv rau hauv kev kuaj mob kom ntsuas qib ntawm cov hlau lead hauv cov neeg mob. Ib qho kev xeem hu ua kev xeem mobilization lead tuaj yeem ua tau los ntawm kev txhaj tshuaj EDTA-Ca rau hauv lub cev tib neeg. Yog tias tus neeg mob tso zis ntau dua 6 grams ntawm cov hlau lead hauv cov zis hauv 24 teev tom qab txhaj tshuaj, qhov tshwm sim ntawm kev xeem yog qhov zoo, uas pab cov kws kho mob nkag siab meej txog tag nrho cov hlau lead hauv tus neeg mob lub cev thiab tsim cov phiaj xwm kho mob kom tsim nyog. Qee qhov kev tshawb fawb kuj tau qhia tias EDTA-Ca yuav muaj qee yam txiaj ntsig rau kev noj qab haus huv ntawm lub plawv, vim nws yuav pab txo qhov kev sib sau ua ke ntawm calcium hauv cov plaques atherosclerotic, tab sis daim ntawv thov no tseem nyob rau theem kev tshawb fawb thiab tsis tau txhawb nqa dav.
EDTA-Ca kuj tseem muaj lub luag haujlwm hauv qee qhov chaw. Hauv kev lag luam, nws siv rau hauv electroplating, textiles, luam ntawv thiab zas xim, tshuaj pleev ib ce thiab lwm yam lag luam ua tus neeg sawv cev sib xyaw thiab stabilizer los txhim kho kev ua haujlwm ntawm cov khoom thiab kev ruaj khov. Hauv kev ua liaj ua teb, nws tuaj yeem siv ua cov khoom ntxiv rau hauv cov tshuaj tua kab thiab chiv, uas tuaj yeem txhim kho kev ruaj khov ntawm cov tshuaj tua kab thiab kev siv cov chiv, thiab txhawb kev loj hlob ntawm cov qoob loo. Hauv kev tiv thaiv ib puag ncig, nws tuaj yeem siv los chelate thiab nqus cov hlau hnyav hauv ib puag ncig, txo cov hlau hnyav ua qias tuaj.
Thaum nws los txog rau kev nyab xeeb ntawmEDTA-Ca, ntau tus neeg yuav muaj kev txhawj xeeb. Qhov tseeb, EDTA-Ca feem ntau suav tias muaj kev nyab xeeb thaum siv hauv cov kev txwv uas tau tswj hwm. Nws tau raug pom zoo ua ib yam khoom muaj kev nyab xeeb los ntawm cov koom haum tswj hwm khoom noj thiab tshuaj hauv ntau lub tebchaws. Cov calcium uas muaj nyob hauv EDTA-Ca ua rau nws tsis tshua muaj feem cuam tshuam rau kev nqus calcium thiab lwm yam minerals tseem ceeb hauv tib neeg lub cev piv rau lwm yam khoom zoo sib xws xws li disodium EDTA.
Unilong Industry Co., Ltd yog ib lub chaw tsim khoom thiabEDTA tus neeg muag khoomRau EDTA-Ca, peb muab cov khoom siv hauv kev lag luam, cov khoom noj khoom haus thiab cov khoom siv tshuaj.
