Determining Iron and Copper Levels with Flame AA Spectrophotometry

**Abstract** The determination of trace metal concentrations, particularly iron and copper, is fundamental in various scientific disciplines, including environmental monitoring and material science. This study employs Flame Atomic Absorption Spectrophotometry (FAAS) to quantify iron and copper in samples with unknown concentrations. FAAS is chosen for its precision and reliability in detecting metal ions. The experiment begins with the preparation of standard solutions, followed by calibration of the spectrophotometer. Samples whose metal concentrations are unknown are then examined. The absorption of light at specific wavelengths corresponding to iron and copper allows for the calculation of their concentrations based on the calibration curve. Results indicate successful identification and quantification of iron and copper, demonstrating the efficacy of FAAS in such analyses. This method provides a streamlined and accurate approach to monitor and determine trace metal concentrations in various sample types.
