Chelation yog ib hom kev sib txuas ntawm ions thiab molecules rau hlau ions. Nws koom nrog kev tsim los yog muaj ob lossis ntau qhov sib cais sib koom ua ke ntawm ib qho polydentate ligand thiab ib qho hauv nruab nrab hlau atom. Cov ligands no hu ua chelants, chelators, chelating agents, los yog sequestering agents.
Yuav ua li cas yog tus chelates?
Chelating cov neeg ua haujlwm yog cov tshuaj sib txuas uas ua rau cov hlau ions tsim kom muaj kev ruaj khov, dej-soluble complex. … Cov tshuaj chelating tshwj xeeb khi hlau, txhuas, lossis tooj liab hauv cov ntshav thiab tuaj yeem siv los kho cov hlau no ntau dhau. Cov tshuaj chelating kuj tseem siv tau rau hauv kev kho mob hnyav hlau lom.
Tus neeg sawv cev chelate yog dab tsi?
Tus neeg sawv cev chelate yog ib yam khoom uas nws cov molecules tuaj yeem tsim ntau daim ntawv cog lus rau ib leeg hlau ion. … Ib qho piv txwv ntawm tus neeg saib xyuas yooj yim 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 chelate ua dab tsi?
Ib tshuaj lom neeg uas khi nruj rau cov hlau ions. Hauv cov tshuaj, cov tshuaj chelates yog siv los tshem tawm cov tshuaj lom ntawm lub cev. Lawv kuj tau kawm txog kev kho mob qog noj ntshav.
Tus neeg sawv cev chelate ntau tshaj yog dab tsi?
Calcium disodium ethylenediamine tetraacetic acid (CaNa2EDTA) yog tus neeg sawv cev siv ntau tshaj plaws. Nws yog derivative ntawm ethylenediamine tetraacetic acid (EDTA); ib qho hluavtaws polyamino-polycarboxylic acid thiab txij li xyoo 1950s tau yog ib qho tseem ceeb rau kev kho mob ntawm cov menyuam yaus lom lom lom zem ntau [12].
