A method of flame atomic absorption analysis has been developed which does not need a light source, such as hollow-cathode lamp, which to produce the radiation absorbed by the analyte atoms. In short, flame photometry (FP) is an atomic technique which measures the wavelength and intensity of light emitted by atoms in a flame resulting from the drop from the excited state (formed due to absorption of energy from the flame) to lower states. 1.2.1 Flame atomic absorption spectroscopy Prior steps to the stage of atomization in flame are the treatment of the sample, dissolving it in a convenient matrix, and the stage of pneumatic nebulisation. The principle of spectrophotometry is the interaction between energy and matter. The determination of potassium using an atomic absorption spectrophotometer requires a light source (wavelength for K = 766.5 nm) and an atomization source (flame).
