Kodi Kusiyana Pakati pa Edta Ndi Sodium Citrate Ndi Chiyani?

Kusiyana kwakukulu pakati pa EDTA ndi sodium citrate ndikuti EDTA ndiyothandiza pakuyezetsa magazi chifukwa imateteza maselo amagazi bwino kuposa othandizira ena ofanana, pomwe sodium citrate ndiyothandiza ngati kuyesa kwa coagulation popeza zinthu V ndi VIII ndizokhazikika pamtunduwu.

Kodi EDTA (Ethylenediaminetetraacetic Acid) ndi chiyani?

EDTA kapena ethylenediaminetetraacetic acid ndi aminopolycarboxylic acid yokhala ndi formula yamankhwala [CH2N(CH2CO2H)2]2.Zimawoneka ngati zolimba zoyera, zosungunuka m'madzi zomwe zimagwiritsidwa ntchito kwambiri pomanga chitsulo ndi ayoni a calcium.Izi zimatha kumangiriza ndi ma ion pamfundo zisanu ndi chimodzi, zomwe zimatsogolera kuti zizidziwika ngati wothandizira wamkulu wa mano (hexadentate) chelating.Pakhoza kukhala mitundu yosiyanasiyana ya EDTA, nthawi zambiri disodium EDTA.

Mwandalama, EDTA ndiyothandiza ngati njira yochotsera ma ion zitsulo munjira zamadzi.Komanso, imatha kuletsa zonyansa za ayoni zachitsulo kuti zisinthe mitundu ya utoto pamakampani opanga nsalu.Kuphatikiza apo, ndizothandiza pakulekanitsa zitsulo za lanthanide ndi ion-exchange chromatography.Pazamankhwala, EDTA ingagwiritsidwe ntchito pochiza mercury ndi poyizoni wotsogolera chifukwa cha kuthekera kwake kumanga ayoni achitsulo ndikuthandizira kuwalekanitsa.Mofananamo, n’kofunika kwambiri pofufuza magazi.EDTA itha kugwiritsidwanso ntchito ngati chophatikizira pazinthu zosamalira anthu monga shampu, zotsukira, ndi zina zotero, ngati wothandizira.

Kodi sodium citrate ndi chiyani?

Sodium citrate ndi organic pawiri wokhala ndi sodium cations ndi citrate anions mosiyanasiyana.Pali mitundu itatu ikuluikulu ya mamolekyu a sodium citrate: monosodium citrate, disodium citrate, ndi trisodium citrate molecule.Pamodzi, mchere atatuwa amadziwika ndi nambala ya E 331. Komabe, mawonekedwe ambiri ndi mchere wa trisodium citrate.

Trisodium citrate ili ndi chilinganizo chamankhwala Na3C6H5O7.Nthawi zambiri, mankhwalawa amatchedwa sodium citrate chifukwa ndi mchere wochuluka kwambiri wa sodium citrate.Chida ichi chimakhala ndi kukoma kwa saline, tart pang'ono.Kuphatikiza apo, mankhwalawa ndi ofunikira pang'ono, ndipo titha kugwiritsa ntchito kupanga ma buffer solution ndi citric acid.Izi zimawoneka ngati ufa wa crystalline woyera.Makamaka, sodium citrate imagwiritsidwa ntchito m'makampani azakudya monga chowonjezera chazakudya, ngati chokometsera kapena chosungira.
