cases [23–25] in order to establish a condition that could satisfy an
optimized condition for all the analytes under study in termsof sensitivity.
The global response employed in this present work is shown below:

where GR is the global response (or combined response) and Ri is the
individual response for each analyte under evaluation.
TheGR function combines the individual responses for Cu, Fe and Pb in
a final response, which was used in the optimization. The individual
response for each analyte was derived from the combination of the
individual absorbance, measured in the injection of the emulsions, with
the relative sensitivity and the actual concentration of each analyte in the
emulsion. The individual responses can be represented by the following
relation:
Ri =
Ai
Si:Ci
where Ri is the individual response for each analyte, Ai is the
individual absorbance measured in each experiment, Si is the relative
sensitivity for each analyte and Ci is the real concentration of each
element in the emulsions used in the experiments.
