In this work, two toxic compound, sulfide and thiocyanate were determined simultaneously
using kinetic spectrophotometry. These anions have shown the catalytic effects on the
reaction between iodine and azide. Since the system was nonlinear, a nonlinear model,
principal component-wavelet neural network (PC-WNN) was used as the multivariate
calibration method. The principal component analysis was used to decrease the dimension
of the original matrix. In other words, the scores of the PCs, 5, instead of the original ...
