Abstract:

Matrix effects in atomic absorption analysis are of several types salinity, and physical properties of the analysis-solution, and the nature of the solvent modify the atomizing of the solution the constituents of the matrix determine the physical reactions in the flame. A knowledge of each of these phenomena permits determination of the proper method of correction. The matrix effect can be interpreted in terms of perturbations of spectral type which result from the superposition of molecular absorption bands on the atomic line being measured. Author
