Chelating agents yog organic compounds muaj peev xwm txuas ua ke hlau ions los tsim cov nplhaib zoo li cov qauv hu ua chelates. Los ntawm: Phau ntawv ntawm Toxicology ntawm Kev Ua Tsov Rog Tshuaj Tshuaj, 2009.
Yuav ua li cas yog tus neeg sawv cev chelate?
Chelating agents yog tshuaj sib txuas uas ua rau cov hlau ions ua kom ruaj khov, dej-soluble complexLawv tseem hu ua chelators, chelators, lossis sequestering agents. Chelating agents muaj lub nplhaib zoo li qhov chaw uas tsim tsawg kawg yog ob daim ntawv cog lus nrog cov hlau ion tso cai rau nws tawm mus.
Cov tshuaj chelates thiab piv txwv yog dab tsi?
Tus neeg sawv cev chelating yog cov khoom uas nws cov molecules tuaj yeem tsim ntau daim ntawv cog lus rau ib leeg hlau ion … Ib qho piv txwv ntawm ib qho yooj yim chelate agent yog ethylenediamine. ethylenediamine. Ib qho molecule ntawm ethylenediamine tuaj yeem tsim ob daim ntawv cog lus rau kev hloov pauv-hlau ion xws li npib tsib xee (II), Ni2 +.
Tus neeg sawv cev chelating yog dab tsi hauv kev tshuaj ntsuam chemistry?
Chelating agents yog tshuaj sib xyaws uas nws cov qauv tso cai rau kev txuas ntawm lawv ob lossis ntau dua tus neeg pub atoms (lossis qhov chaw) rau tib lub hlau ion ib txhij thiab tsim ib lossis ntau lub nplhaib.
Cov tshuaj chelate ua haujlwm li cas?
Chelators ua haujlwm los ntawm kev khi rau cov hlau hauv cov hlab ntsha Thaum lawv tau txhaj rau hauv cov hlab ntsha, lawv ncig los ntawm cov ntshav, khi rau cov hlau. Ua li no, chelators sau tag nrho cov hlau hnyav rau hauv ib qho chaw uas tau lim los ntawm ob lub raum thiab tso tawm hauv cov zis.
