Taw qhia
Cov khoom no tuaj yeem siv rau kev tshawb fawb txog kev sim hauv cov haujlwm uas muaj feem xyuam. Photometric ntsuas ntawm hlau Fe (II) thiab tag nrho cov hlau. Cov xim ntawm Fe2 + complex yog xim liab liab ntawm pH 3.4-5.8 (1: 2, logK = 20.4), thiab TPTZ tuaj yeem siv los ua cov ntsuas hlau ntawm Fe. Txawm li cas los xij, TPTZ thiab hlau ions xws li Co, Cu thiab Ni kuj tseem yuav xim, yog li nws tsis tuaj yeem siv los ua cov xim xim xim rau Fe. Yog tias muaj coob tus Co, Cu thiab Ni ions, nws yuav cuam tshuam qhov kev tshawb pom. Ntxiv nrog rau Fe ions hauv cov dej ntshiab thiab cov dej boiler, tseem muaj cov lus ceeb toom tias Fe hauv cov qauv xws li iav, thee, hlau purity siab, cawv, thiab vitamin E tuaj yeem suav tau.
