Uyini Umehluko Phakathi Kwe-Edta Ne-Sodium Citrate?

Umehluko oyinhloko phakathi kwe-EDTA ne-sodium citrate ukuthi i-EDTA iwusizo ekuhloleni i-hematological ngoba igcina amangqamuzana egazi kangcono kunamanye ama-ejenti afanayo, kuyilapho i-sodium citrate iwusizo njenge-ejenti yokuhlola i-coagulation njengoba izici V kanye ne-VIII zizinzile kule nto.

Iyini i-EDTA (Ethylenediaminetetraacetic Acid)?

I-EDTA noma i-ethylenediaminetetraacetic acid iyi-aminopolycarboxylic acid enefomula yamakhemikhali [CH2N(CH2CO2H)2]2.Kubonakala njengento eqinile emhlophe, encibilika emanzini esetshenziswa kakhulu ekubopheni i-iron ne-calcium ions.Le nto ingabopha nalawo ma-ion ngamaphuzu ayisithupha, okuholela ekutheni yaziwe njenge-agent chelating (i-hexadentate) enamazinyo.Kungase kube nezinhlobo ezahlukene ze-EDTA, ngokuvamile i-disodium EDTA.

Ngokwezimboni, i-EDTA ilusizo njenge-ejenti yokuthungatha ama-ion ensimbi ezixazululweni ezinamanzi.Ngaphezu kwalokho, ingavimbela ukungcola kwe-ion yensimbi ekuguquleni imibala kadayi embonini yendwangu.Ngaphezu kwalokho, iwusizo ekuhlukaniseni izinsimbi ze-lanthanide nge-ion-exchange chromatography.Emkhakheni wezokwelapha, i-EDTA ingasetshenziselwa ukwelapha i-mercury kanye nobuthi bomthofu ngenxa yekhono layo lokubopha ama-ion ensimbi nokusiza ekuwahlukaniseni.Ngokufanayo, kubaluleke kakhulu ekuhlaziyeni igazi.I-EDTA ingasetshenziswa futhi njengesithako emikhiqizweni yokunakekelwa komuntu siqu njenge-shampoo, izinto zokuhlanza, njll., njenge-ejenti yokuthungatha.

Iyini i-Sodium Citrate?

I-sodium citrate iyinhlanganisela ye-inorganic ene-sodium cations nama-anion citrate ngezilinganiso ezahlukene.Kunezinhlobo ezintathu ezinkulu zama-molecule e-sodium citrate: i-monosodium citrate, i-disodium citrate, ne-molecule ye-trisodium citrate.Ngokuhlangene, lawa masawoti amathathu aziwa ngenombolo E 331. Nokho, ifomu elivame kakhulu usawoti we-trisodium citrate.

I-Trisodium citrate inefomula yamakhemikhali ethi Na3C6H5O7.Esikhathini esiningi, lesi sakhi sivame ukubizwa ngokuthi i-sodium citrate ngoba iwuhlobo oluningi kakhulu lukasawoti we-sodium citrate.Le nto ine-saline-like, tart flavour kancane.Ngaphezu kwalokho, le nhlanganisela iyisisekelo esincane, futhi singayisebenzisa ukwenza izixazululo ze-buffer kanye ne-citric acid.Le nto ibonakala njengempushana emhlophe ecwebezelayo.Ngokuyinhloko, i-sodium citrate isetshenziswa embonini yokudla njengesengezo sokudla, njengesinongo noma njengesilondolozi.

I-EDTA noma i-ethylenediaminetetraacetic acid iyi-aminopolycarboxylic acid enefomula yamakhemikhali [CH2N(CH2CO2H)2]2.I-sodium citrate iyinhlanganisela ye-inorganic ene-sodium cations nama-anion citrate ngezilinganiso ezahlukene.Umehluko oyinhloko phakathi kwe-EDTA ne-sodium citrate ukuthi i-EDTA iwusizo ekuhlolweni kwe-hematological ngoba igcina amangqamuzana egazi kangcono kunamanye ama-ejenti afanayo, kuyilapho i-sodium citrate iwusizo njenge-ejenti yokuhlola i-coagulation ngoba izici V kanye ne-VIII zizinzile kule nto.
