Question

Why r u used potassium dichromate in uv calibration?

Answer 1

Some points: Potassium dichromate is especially useful in the visible range but also useful in UV. Potassium dichromate itself is stable and avaialble in high purity. In dilute perchloric acid solution, it has a linear response with good temperature stability and also stable as solution. The peaks are well defined, molar absorptivity at 350 nm is accuratly known . You can find much more information in old classical analytical and spectroscopic text books and from NIST (xNBS).


I hope it helps you.
