SUMMARY
The discussion focuses on analyzing mercury in the presence of cobalt using Atomic Absorption Spectroscopy (AAS), specifically at the wavelength of 235.65 nm where both elements exhibit absorption. Cold vapour AAS is identified as the method for examining mercury, which involves reducing mercury to its elemental form due to its high vapor pressure. The challenge lies in distinguishing between the signals of mercury and cobalt during analysis, as both elements can interfere with each other's detection.
