Kev Tshuaj Xyuas COD Hauv Online
Txoj Cai Tshawb Nrhiav
Ntxiv ib qho tshuaj potassium dichromate uas paub lawm rau hauv cov qauv dej, thiab siv ntsev nyiaj ua tus catalyst thiab mercury sulfate ua tus neeg sawv cev masking hauv cov kua qaub muaj zog. Tom qab qhov kub thiab txias siab thiab siab siab zom cov tshuaj tiv thaiv, nrhiav qhov absorbance ntawm cov khoom ntawm qhov wavelength tshwj xeeb. Raws li Lambert Beer txoj cai, muaj kev sib raug zoo ntawm cov tshuaj oxygen thov hauv dej thiab qhov absorbance, thiab tom qab ntawd txiav txim siab qhov concentration ntawm cov tshuaj oxygen thov hauv dej. Nco ntsoov: Muaj cov tshuaj nyuaj rau oxidize xws li aromatic hydrocarbons thiab pyridine hauv cov qauv dej, thiab lub sijhawm zom zaub mov tuaj yeem ntev dua.
