The physical effects and interferences that the method of standard additions would correct or compensate for in AAS should be described. Concept introduction: Standard addition is a method which is referred to as the technique of quantitative analysis to lower the effects of the matrix interfering in the signals of analyte measurement. Interference is a type of phenomenon which leads to fluctuations in the intensity of the signals of analyte measurements in spectroscopy.

Question
