Yintoni Umahluko phakathi kwe-Edta kunye neSodium Citrate?

Umahluko ophambili phakathi kwe-EDTA kunye ne-sodium citrate kukuba i-EDTA iluncedo kwiimvavanyo ze-hematologic kuba igcina iiseli zegazi ngcono kunezinye ii-agent ezifanayo, kanti i-sodium citrate iluncedo njenge-agent yokuvavanya i-coagulation ekubeni izinto ze-V kunye ne-VIII zizinzile kule nto.

Yintoni i-EDTA (Ethylenediaminetetraacetic Acid)?

I-EDTA okanye i-ethylenediaminetetraacetic acid yi-aminopolycarboxylic acid ene-chemical formula [CH2N(CH2CO2H)2]2].Kubonakala njengento emhlophe, eqinileyo enyibilikayo emanzini esetyenziswa ngokubanzi ekubopheni i-iron kunye ne-calcium ion.Le nto inokubophelela kunye nezo ion kumanqaku amathandathu, nto leyo ekhokelela ekubeni yaziwe njenge-agent ye-chelating ye-size-toothed (hexadentate).Kunokubakho iindlela ezahlukeneyo ze-EDTA, eyona idla ngokuba yi-disodium EDTA.

Kwimizi-mveliso, i-EDTA iluncedo njenge-arhente yokuhlutha ii-ion zesinyithi kwizisombululo ezinamanzi.Ngaphezu koko, inokuthintela ukungcola kwe-ion yesinyithi ekuguquleni imibala yedayi kwishishini lelaphu.Ukongezelela, luncedo ekuhlukaneni kweentsimbi ze-lanthanide nge-ion-exchange chromatography.Kwintsimi yeyeza, i-EDTA ingasetyenziselwa ukunyanga i-mercury kunye netyhefu yelothe ngenxa yokukwazi ukubopha i-ion zetsimbi kunye nokunceda ekwahluleni.Ngokufanayo, kubaluleke kakhulu kuhlalutyo lwegazi.I-EDTA isenokusetyenziswa njengesithako kwiimveliso zokhathalelo lomntu ezifana neshampu, izicoci, njl.njl., njenge-arhente yokuhlutha.

Yintoni iSodium Citrate?

I-sodium citrate yikhompawundi ye-inorganic ene-sodium cations kunye ne-citrate anions kwimilinganiselo eyahlukeneyo.Kukho iintlobo ezintathu eziphambili zeamolekyuli ze-sodium citrate: i-monosodium citrate, i-disodium citrate, kunye ne-molecule ye-trisodium citrate.Ngokudibeneyo, ezi zintathu zetyuwa ziyaziwa ngenombolo ye-E 331. Nangona kunjalo, ifom eqhelekileyo yityuwa ye-trisodium citrate.

I-Trisodium citrate ine-chemical formula Na3C6H5O7.Uninzi lwexesha, le khompawundi ngokuqhelekileyo ibizwa ngokuba yi-sodium citrate kuba iyona ndlela ininzi yetyuwa ye-sodium citrate.Le nto inencasa efana ne-saline, i-tart encinci.Ngaphaya koko, le khompawundi isisiseko ngokuthobekileyo, kwaye sinokuyisebenzisa ukwenza izisombululo ze-buffer kunye ne-citric acid.Le nto ibonakala njengomgubo omhlophe wekristale.Ngokuyintloko, i-sodium citrate isetyenziswa kwishishini lokutya njengesongezo sokutya, njengesiqholo okanye njengesigcinakaliso.

Uthini Umahluko phakathi kwe-EDTA kunye neSodium Citrate?

I-EDTA okanye i-ethylenediaminetetraacetic acid yi-aminopolycarboxylic acid ene-chemical formula [CH2N(CH2CO2H)2]2.I-sodium citrate yikhompawundi ye-inorganic ene-sodium cations kunye ne-citrate anions ngokwemilinganiselo eyahlukeneyo.Umahluko ophambili phakathi kwe-EDTA kunye ne-citrate ye-sodium kukuba i-EDTA iluncedo kuvavanyo lwe-hematologic kuba igcina iiseli zegazi zingcono kunezinye i-agent ezifanayo, kanti i-sodium citrate iluncedo njenge-agent yokuvavanya i-coagulation kuba izinto ze-V kunye ne-VIII zizinzile kule nto.
