Uyini umehluko phakathi kwe-Edta ne-sodium citrate?

Umehluko osemqoka phakathi kwe-EDTA ne-sodium citrate ukuthi i-Edta ilusizo ekuhlolweni kwe-hematologic ngoba igcina amaseli egazi kangcono kunamanye ama-ejenti afanayo, kanti i-sodium citrate ilusizo njenge-ejenti yokuhlolwa kwe-cooational v noViii bazinze kakhulu kule nto.

Yini i-Edta (ethyleniaminetetetraetic acid)?

I-Edta noma i-Ethyleniaminettettetracetic acid iyinhlangano ye-aminopolyboxylic acid enefomula yamakhemikhali [CH2N (CH2CO2H) 2] 2. Kuvela njengesiqu esimhlophe, esinyibilikisiwe amanzi esisetshenziswa kabanzi ekubopheni kwensimbi ne-calcium ions. Le nto ingabopha nalawo ma-ion ngamaphuzu ayisithupha, okuholela kuthiwa waziwa ngokuthi yi-ejenti yosayizi (i-hexadentate). Kungaba nezindlela ezahlukahlukene ze-Edta, evame kakhulu i-dirodium Edta.

I-Indertilly, i-Edta ilusizo njenge-ejenti yokuhlala e-Sequester Ngaphezu kwalokho, kungavimbela ukungcola kwensimbi ion ukuguqula imibala yedayi embonini yezindwangu. Ngaphezu kwalokho, kuyasiza ekuhlukaniseni izinsimbi zeLanthanide nge-Ion-Exchange Chromatography. Ensimini yezokwelapha, i-EDTA ingasetshenziselwa ukwelapha ubuthi be-mercury kanye nokuholela ubuthi ngenxa yekhono labo lokubopha i-metal ion futhi basize ekuhlukaniseni. Ngokufanayo, kubalulekile kakhulu ekuhlaziyeni kwegazi. I-Edta nayo ingasetshenziswa njengesithako emikhiqizweni yokunakekelwa komuntu siqu efana ne-shampoo, izihlanza, njll., Njengomenzeli wokuhlala.

Kuyini i-sodium citrate?

I-sodium citrate iyindawo yokuhlanganisa i-inorganic enayo ama-sodium mations nama-citrate anions ngezilinganiso ezihlukile. Kunezinhlobo ezintathu ezinkulu zama-molecule e-sodium citrate: i-monosodium citrate, i-dirodium citrate, ne-trisodium citrate molecule. Ngokubambisana, lawo usawoti amathathu ayaziwa ngenombolo ye-331. Kodwa-ke, ifomu elijwayelekile kakhulu ngusawoti we-trisodium citrate.

I-trisodium citrate inefomula yamakhemikhali na3c6h5o7. Esikhathini esiningi, le mpikiswano ivame ukubizwa ngokuthi i-sodium citrate ngoba iyisimo esiningi kakhulu sosawoti we-sodium citrate. Le nto inokufana nosawoti, ukunambitheka okuthe xaxa. Ngaphezu kwalokho, le mpikiswano iyisisekelo sobumnene, futhi singayisebenzisa ukwenza izixazululo ze-buffer kanye ne-citric acid. Le nto ibonakala njengempuphu emhlophe ye-crystalline. Ngokuyinhloko, i-sodium cirtrate isetshenziswa embonini yokudla njengezengezo zokudla, njengokunambitheka noma njengokulondolozwa.

Umehluko osemqoka phakathi kwe-EDTA ne-sodium citrate ukuthi i-Edta ilusizo ekuhlolweni kwe-hematologic ngoba igcina amaseli egazi kangcono kunabanye abenzeli abafanayo, izici v ne-VIII zizinzile kakhulu kule nto.
