THE LINEAR ABSORBANCES METHOD ADAPTED TO SYSTEMS WITH 2 INTERFERING COMPOUNDS - THEORETICAL AND EXPERIMENTAL-STUDY

The paper exposes the theoretical and experimental study performed wit h the purpose to extend the application of the Linear Absorbances Meth od to more complex systems, which present two spectral interferences. The curves of collinearity are developed and a theoretical study of th em is carried out. The theoretical equations developed are experimenta lly tested and the influence of the variables involved in the Linear A bsorbance Method is studied, too. It is concluded that the use of coup les of collinear wavelengths of the interferents allows to obtain the concentration of a compound in the presence of two interfering substan ces.
