Khoom Taw Qhia Thiab Daim Ntawv Thov
Disodium ethylenediaminetetraacetic acid, tseem hu ua EDTA disodium ntsev, yog cov xim tsis muaj kob crystalline. Nws muaj zoo solubility thiab siab solubility hauv dej. Disodium ethylenediaminetetraacetic acid muaj zog chelating muaj peev xwm thiab tuaj yeem tsim cov complexes nrog hlau ions, tshwj xeeb tshaj yog rau divalent hlau ions.
Daim ntawv thov:Kev siv lub ntsiab ntawm disodium ethylenediaminetetraacetic acid yog raws li tus neeg sawv cev chelating thiab complexing tus neeg sawv cev. Nws tuaj yeem siv rau hauv kev kho dej, textile dyeing, resin stabilizers, cog cov as-ham, thiab lwm yam. Hauv kev tshuaj xyuas tshuaj, nws yog feem ntau siv hauv kev sib koom tes titration los txiav txim siab cov ntsiab lus ntawm cov hlau ions.
