Introduction
Estimation of iron by Atomic absorption spectroscopy
Atomic Absorption Spectroscopy (AAS) technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed. AAS can be used to determine over 70 different elements in solution or directly in solid samples. this technique finds aplications in pharmacology, biophysics and toxicology etc.
This lesson gives students the basic idea about the principle and estimation of iron by AAS method
Task
At the end of this activity the students will get the information about the different light sources, instrumentation, working of AAS and its application in the estimation of iron
