● Siv 2,7-Disulfonaphthalene Disodium ntsev yog ib qho tshuaj ntsuam xyuas siv los kawm anion xaiv kev txhaj tshuaj-sweep-micellar eletrokinetic chromatography.
2,7-Naphthalenedisulfonic acid disodium ntsev yog cov tshuaj sib xyaw nrog cov mis molecular C10H6Na2O6S2.Nws yog ib qho ntsev disodium ntawm 2,7-naphthalenedisulfonic acid, uas txhais tau hais tias nws muaj ob lub sodium ions (Na+) uas cuam tshuam nrog sulfonic acid pawg (-SO3H) txuas rau lub nplhaib naphthalene ntawm 2 thiab 7 txoj haujlwm. feem ntau pom raws li ib tug dawb los yog tawm-dawb crystalline hmoov thiab yog heev dej-soluble.Nws yog feem ntau yog siv los ua cov xim nruab nrab hauv kev tsim cov dyes reactive, acid dyes, thiab cov dyes ncaj qha.Daim ntawv ntsev disodium txhim khu lub solubility thiab stability ntawm cov compound nyob rau hauv dej-raws li formulations.2,7-Naphthalenedisulfonic acid disodium ntsev kuj yuav siv tau raws li ib tug pH regulator los yog buffering tus neeg saib xyuas nyob rau hauv ntau yam kev lag luam txheej txheem.Nws cov pab pawg sulfonic acid ua rau nws cov kua qaub heev, uas tuaj yeem siv rau hauv cov ntawv thov uas yuav tsum tau tswj pH. Zoo li txhua yam tshuaj lom neeg, nws yog ib qho tseem ceeb uas yuav tsum tau ua 2,7-Naphthalenedisulfonic acid disodium ntsev nrog kev saib xyuas thiab ua raws li kev ceev faj txog kev nyab xeeb.Nws raug nquahu kom tshuaj xyuas cov ntaub ntawv kev nyab xeeb cov ntaub ntawv (MSDS) thiab ua raws li tag nrho cov lus qhia txog kev nyab xeeb thaum ua haujlwm nrog cov khoom sib xyaw no.
