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.

WebSpectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. [2] Spectrophotometry uses photometers, known as spectrophotometers, that can measure the intensity of a light beam at different wavelengths. WebThere are four main stages which occur during this flame emission spectroscopy. 1. Evaporation: The sample containing metal particles is dehydrated by the heat of the flame and the solvent is evaporated. 2. Atomisation: At this stage the metal ions that were in the solvent are reduced to metal atoms. For example, Mg2+ (aq) + 2e → Mg (g). diabetic calf socks cheap
