Homework Help: AAS of mercury in prescence of cobalt

  1. Mar 16, 2008 #1
    Just wondering how to analyse mercury in the presence of cobalt by atomic absorption analysis given that both elements emit and absorb radiation at 235.65nm.
    I know that mercury isj examined using cold vapour atomic absorbtion analysis... but knowing this still doesnt help????????

    Any hints would be appreciated

    Cold vapour AAS is a method in which mercury is reduced in the sample to elemental mercury which has a fairly high vapor pressure. What do you suppose the vapor pressure of zero valent cobalt might be?
