Kev siv Ethylenediaminetetraacetic Acid (EDTA)

Ethylenediaminetetraacetic Acid (EDTA) yog ib qho kev sib xyaw ua ke uas muaj ntau yam kev siv hauv ntau yam lag luam. Nws complexing thiab chelating zog ua rau nws yog ib qho tseem ceeb reagent nyob rau hauv ntau daim ntawv thov uas nws yog siv raws li ib tug stabilizer, detergent, thiab sequestering neeg sawv cev.
Cov mis mos molecular ntawm EDTA yog C10H16N2O8 thiab cov compound muaj qhov hnyav molecular ntawm 292.24 g / mol. Nws yog cov xim tsis muaj xim crystalline thiab yog soluble hauv dej heev. EDTA muaj ntau yam pH ruaj khov, nrog rau qhov zoo ntawm pH 7 thiab 9.
Ib qho ntawm cov kev siv ntau tshaj plaws ntawm EDTA yog ua tus neeg saib xyuas hauv kev lag luam khoom noj. Nws tau ntxiv rau ntau yam khoom noj thiab dej haus los tiv thaiv kev tsim cov hlau ion complexes uas tuaj yeem ua rau tsis muaj xim, tawm tsw, thiab rancidity. EDTA kuj tseem siv nyob rau hauv kev lag luam tshuaj pleev ib ce, qhov chaw uas nws ua hauj lwm raws li ib tug stabilizer nyob rau hauv cov tshuaj zawv plaub hau thiab conditioners.
EDTA kuj tau siv dav hauv cov tshuaj thiab chaw kuaj mob. Nws muaj ntau yam kev siv kho mob, suav nrog ua cov tshuaj tiv thaiv coagulant rau kev sau ntshav, ua chelator rau hnyav hlau lom, thiab ua tus activator hauv kev kuaj ntshav. EDTA kuj tseem siv tau los ua cov tshuaj tua kab mob hauv qee cov khoom siv tshuaj, xws li tshuaj tua kab mob thiab tshuaj tua kab mob.
Ntxiv rau nws cov kev lag luam thiab kev siv kho mob, EDTA kuj tseem siv rau hauv kev tshuaj ntsuam chemistry. Nws yog feem ntau siv los ua tus neeg sawv cev complexing hauv spectrophotometric titration ntawm hlau ions. EDTA kuj tseem siv los ua qhov tsis nyob hauv qee qhov kev tshawb fawb ntawm cov tshuaj tiv thaiv enzymatic.
Txawm li cas los xij, kev siv EDTA tau muaj teeb meem vim nws muaj peev xwm cuam tshuam ib puag ncig. EDTA tsis yog biodegradable, thiab nws cov tsub zuj zuj hauv ib puag ncig tuaj yeem muaj qhov tsis zoo rau cov dej hauv dej. Vim li no, qee lub tebchaws tau ua cov kauj ruam los txwv nws txoj kev siv hauv qee yam khoom thiab kev siv.
Zuag qhia tag nrho, EDTA yog ntau yam sib xyaw nrog kev siv dav hauv ntau qhov kev lag luam. Nws zoo heev complexing thiab chelating zog ua rau nws ib tug tseem ceeb reagent nyob rau hauv ntau yam sib txawv chaw. Txawm hais tias nws siv tau muaj teeb meem, kev coj ua kom raug thiab pov tseg tuaj yeem pab txo qis nws qhov cuam tshuam ib puag ncig.
