Online COD Analyzer
Detection Principple
Ntxiv ib qho kev paub txog cov tshuaj potassium dichromate rau cov qauv dej, thiab siv cov ntsev ntsev los ua cov tshuaj tiv thaiv thiab mercury sulfate ua tus neeg sawv cev npog hauv cov kua qaub nruab nrab. Tom qab kub-kub thiab siab-siab digestion cov tshuaj tiv thaiv, xyuas cov absorbance ntawm cov khoom ntawm ib tug tshwj xeeb wavelength. Raws li Lambert Beer txoj cai, muaj ib qho kev sib raug zoo ntawm cov tshuaj oxygen xav tau cov ntsiab lus hauv dej thiab qhov nqus dej, thiab tom qab ntawd txiav txim siab cov ntsiab lus ntawm cov tshuaj oxygen xav tau hauv dej.Note: Muaj qhov nyuaj rau oxidize cov khoom xws li aromatic hydrocarbons thiab pyridine hauv cov qauv dej, thiab lub sijhawm zom zaub mov tuaj yeem tsim nyog txuas ntxiv.
