4 thiab EDTA

EDTA-4NA

EDTA, los yog ethylenediaminetetraacetic acid, yog synthesized los ntawm reacting ethylenediamine nrog chloroacetic acid nyob rau hauv lub xub ntiag ntawm sodium hydroxide. Cov tshuaj tiv thaiv yields nws nrog rau sodium chloride. Lub cev lub cev ntawm nws muaj xws li ib tug dawb crystalline hmoov tsos, nrog ib tug melting point ntawm ib ncig ntawm 240-250 degree . Nws yog me ntsis soluble hauv dej txias tab sis yooj yim yaj hauv dej kub thiab acids. Nws yog tus neeg sawv cev chelating, tsim cov khoom ruaj khov nrog cov hlau ions, thiab tau siv dav hauv kev lag luam xws li tshuaj, tshuaj ntxuav tes, thiab dej kho rau nws lub peev xwm los muab cov hlau ions.

EDTA, los yog ethylenediaminetetraacetic acid, yog ib tug ntau yam chelating neeg sawv cev uas feem ntau siv nyob rau hauv ntau yam kev lag luam, kev kho mob, thiab kev siv scientific vim nws muaj peev xwm los khi hlau ions. Ib qho ntawm nws cov ntawv tshwj xeeb yog hauv cov tshuaj, qhov twg EDTA yog siv los ua tus neeg sawv cev chelate los kho cov tshuaj lom neeg hnyav. EDTA tsim cov khoom ruaj khov nrog cov hlau tsis zoo xws li txhuas, mercury, cadmium, thiab arsenic, ua kom yooj yim rau lawv tawm ntawm lub cev. Txoj kev kho chelation no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum mob hnyav lossis mob hnyav hlau lom, pab txo cov tshuaj lom thiab txo cov kev pheej hmoo ntawm kev noj qab haus huv. Tsis tas li ntawd, EDTA 4NA (tetrasodium ntsev ntawm EDTA) yog siv nyob rau hauv ntau yam kev kuaj cov txheej txheem, suav nrog molecular biology thiab biochemistry, qhov tseeb hlau ion concentrations yog ib qho tseem ceeb rau kev sim raug.
