WebJan 8, 2024 · In chemistry, the flame test is a simple qualitative analysis technique to check for the presence of alkali, alkaline-earth metal ions and some transition metals. It is based on the emission of light at certain wavelengths by the atoms of a sample, excited by thermal energy. A small amount of sample – or a solution of it in hydrochloric acid ... WebAtomic absorption spectroscopy uses light in the ultraviolet-visible range. For Pb analysis, a thin beam of light is passed through the flame containing the analyte. The beam contains light at 283.3 nm. The light is absorbed by Pb atoms as excitation of electrons from the Pb ground state to the first energy level occurs.
