    What is potassium dichromate maximum wavelength using UV specrophotometer?
    I am going to measure the concentration of cr by using UV spetrophotometer.
    I want to know what is the maximum wave length of potassium dichromate to figure the calibration curve of it.

    It really depends on your matrix (if you can, make a scan on your spectrophotometer) - but try 257 nm.
