Chelating agents chemicals yog ib pawg ntawm cov tebchaw uas muaj peev xwm tsim kev sib koom tes nrog cov hlau ions. Cov complexes yog tsim thaum tus neeg sawv cev chelating khi nrog cov hlau ion los ntawm ntau qhov chaw, tsim kom muaj lub nplhaib ruaj khov zoo li cov qauv nyob ib ncig ntawm cov hlau ion. Cov txheej txheem no feem ntau hu ua chelation thiab feem ntau siv hauv kev lag luam thiab tshuaj.
Cov tshuaj no tau siv dav hauv ntau yam kev lag luam xws li kev kho dej, textile, thiab pulp thiab ntawv kev lag luam, nrog rau hauv kev lag luam khoom noj thiab tshuaj. Hauv cov kev lag luam no, cov neeg ua haujlwm chelating yog siv los ua cov khoom ntxiv los tiv thaiv cov kev xav tsis zoo thiab txhim kho tag nrho cov txiaj ntsig ntawm cov txheej txheem.
Hauv kev lag luam khoom noj khoom haus, cov tshuaj chelates tau ntxiv rau cov khoom noj khoom haus los tiv thaiv cov khoom noj kom zoo thiab ruaj khov. Piv txwv li, tus neeg sawv cev chelating EDTA (ethylenediaminetetraacetic acid) feem ntau yog siv los tiv thaiv cov zaub thiab txiv hmab txiv ntoo tsis muaj xim. Nws kuj pab khaws cov tsw thiab kev ntxhib los mos ntawm cov khoom noj no.
Hauv kev kho mob, cov tshuaj chelate yog siv los tshem tawm cov tshuaj lom ntawm lub cev. Cov txheej txheem no hu ua chelation therapy thiab yog siv los kho cov mob xws li hnyav hlau lom, atherosclerosis, thiab qee hom mob qog noj ntshav. Chelating cov neeg ua haujlwm khi nrog cov tshuaj lom hauv lub cev, tsim cov complexes uas tom qab ntawd tshem tawm ntawm lub cev los ntawm cov zis.
Txawm li cas los xij, cov tshuaj chelates kuj tuaj yeem cuam tshuam tsis zoo rau ib puag ncig yog tias lawv tsis muab pov tseg kom raug. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm EDTA, nws yog feem ntau siv nyob rau hauv xab npum thiab tu cov khoom. Thaum cov khoom no raug ntxuav hauv qhov ntws, EDTA tuaj yeem khi nrog cov hlau hauv cov dej khib nyiab, ua rau nws nyuaj rau tshem tawm cov hlau ntawm cov chaw kho dej khib nyiab.
Hauv kev xaus, chelate agents chemicals ua lub luag haujlwm tseem ceeb hauv kev lag luam thiab tshuaj. Lawv yog siv los txhim kho kev ua tau zoo thiab zoo ntawm ntau yam txheej txheem thiab tseem tuaj yeem siv los kho cov mob. Txawm li cas los xij, lawv cov kev siv yuav tsum tau saib xyuas thiab lawv cov khoom pov tseg yuav tsum tau tswj xyuas kom zoo kom tsis txhob muaj kev cuam tshuam tsis zoo rau ib puag ncig.
