Qhov Tseem Ceeb Qhov txawv - Chelating Agent vs Sequestering Agent
Chelating agents thiab sequestering agents tshem cov hlau ions los ntawm kev daws teeb meem los ntawm kev tsim cov complex nrog cov hlau ion tshwj xeeb. Cov txheej txheem no hu ua chelation. Nws tuaj yeem siv los tshem tawm cov dej tawv lossis cov hlau hnyav los ntawm cov dej. Ntau cov chelators thiab sequestrants muaj hlau ion nyiam, uas txhais tau hais tias, lub chelator lossis sequestrant yuav khi nrog ib qho hlau ion ua ntej khi nrog lwm cov hlau ions hauv qhov system. Qhov sib txawv tseem ceeb ntawm tus neeg saib xyuas chelating thiab tus neeg saib xyuas sequestering yog tias tus neeg sawv cev chelating tuaj yeem khi nrog ib qho hlau ion thaum tus neeg sawv cev sequestering tuaj yeem khi nrog ob peb hlau ions ib zaug.
Tus neeg saib xyuas Chelating yog dab tsi?
Tus neeg sawv cev chelate yog ib yam khoom uas muaj peev xwm ua tau ob peb daim ntawv cog lus nrog ib qho hlau ion thiab tsim ib qho nyuaj. Cov hlau ion tsis tuaj yeem koom nrog lwm cov tshuaj tiv thaiv uas tshwm sim hauv lub cev vim kev tsim cov txheej txheem. Qhov no yog hu ua chelation. Yog hais tias tus neeg sawv cev chelate ua ob daim ntawv cog lus nrog cov hlau ions, tus neeg sawv cev chelate hu ua bidentate; yog tias nws tsim ntau daim ntawv cog lus, nws yog hu ua multidentate.
Tus neeg sawv cev chelates tsim cov dej ruaj khov soluble ntawm cov hlau. Qhov no tiv thaiv cov hlau los ntawm kev koom nrog hauv nws cov tshuaj tiv thaiv ib txwm muaj. Chelating tus neeg sawv cev tsim kev sib koom tes nrog cov hlau ion, hloov cov qauv tshuaj ntawm cov hlau ion. Chelating cov neeg ua haujlwm tseem ceeb heev hauv cov tshuaj tiv thaiv. Yog tias qhov kev daws teeb meem muaj qhov sib xyaw ntawm ob lub hlau ions, peb tuaj yeem ntxiv tus neeg sawv cev chelating los tiv thaiv lwm cov hlau ion los ntawm kev cuam tshuam hauv cov tshuaj tiv thaiv txhawm rau txhawm rau nrhiav tus nqi ntawm ib qho hlau ion tam sim no hauv cov tshuaj. Chelating agents yog ntuj los yog hluavtaws organic tebchaw siv nyob rau hauv industrial lossis biological applications.
Ib qho piv txwv zoo ntawm tus neeg sawv cev chelate yog Ethylenediamine. Nws tuaj yeem tsim ob daim ntawv cog lus nrog kev hloov pauv hlau ions xws li Nickel (II). Cov nickel ion muaj rau covalent electrons; Hauv lwm lo lus, nws muaj peb khub ntawm electrons. Yog li, peb Ethylenediamine molecules yuav khi nrog ib lub hlau ion.
Lwm qhov piv txwv yog EDTA. Nws feem ntau yog siv hauv xab npum thiab tshuaj ntxuav tes txij li EDTA molecule tuaj yeem khi nrog calcium thiab magnesium ions hauv cov dej tawv, tiv thaiv kev cuam tshuam hauv kev tu cov xab npum thiab tshuaj ntxuav tes.

Tus Neeg Ua Haujlwm Sequestering yog dab tsi?
Cov tshuaj tiv thaiv yog cov tshuaj lom neeg uas tuaj yeem khi nrog cov hlau ions hauv kev daws teeb meem. Kev sib xyaw ua ke ntawm tus neeg sawv cev sequestering thiab cov hlau ions ua kom ruaj khov, dej soluble complex. Tom qab ntawd cov hlau ion tshwj xeeb tsis tuaj yeem ua rau lwm yam kev cuam tshuam (cov tshuaj tiv thaiv uas cov hlau ion nkag mus thaum tsis muaj tus neeg sawv cev sequestering). Txawm hais tias nws qhia tib yam nkaus li tus neeg sawv cev chelating, nws txawv ntawm tus neeg sawv cev chelate los ntawm nws txoj kev "txheej" hlau ion; Sequestering cov neeg ua haujlwm yog tsim los ntawm ob peb qhov chaw nquag uas tuaj yeem khi nrog cov hlau ions. Qhov no ua rau tus neeg sawv cev sequestering muaj zog dua li tus neeg sawv cev chelate vim tias tus neeg sawv cev chelate tuaj yeem khi nrog ib qho hlau ion xwb.
Feem ntau, cov hlau ions zoo ib yam li cov saw hlau. Tom qab ntawd qhov kev khi ntawm cov neeg ua haujlwm sequestering mus rau qhov kawg ntawm cov chains tsim cov qauv zoo li lub nplhaib uas tuaj yeem tshem tau yooj yim.
Dab tsi zoo sib xws ntawm Chelating Agent thiab Sequestering Agent?
- Cov neeg thov kev thov kuj yog ib hom tshuaj chelate.
- Ob tus neeg ua haujlwm chelating thiab sequestering tuaj yeem khi nrog cov hlau ions hauv kev daws teeb meem thiab tuaj yeem tiv thaiv cov hlau ion los ntawm kev ua raws li nws cov kev xav.
- Chelating agents thiab sequestering agents yog cov organic compounds uas tuaj yeem yog ntuj lossis hluavtaws.
- Ob leeg tuaj yeem tsim ruaj khov, dej soluble complexes nrog hlau ions.
