A membrane optode was developed utilizing the 8-hydroxyquinaldine (HQ) facilitated preconcentration of UO(2)(2+) ions and subsequent colored complex formation of UO(2)(2+) with 4-(2-thiazolylazo)-resorcinol (TAR) in optode matrix. The composition of the membrane optode was optimized by scanning several extractants immobilized

The acidity constants of 4-(2-thiazolylazo)-resorcinol (TAR) were determined by the principal component-wavelet neural network (WNN). Biprotic acid mass balance equations, the distribution functions and the corresponding spectral profiles which were generated by a Gaussian model, have been considered to simulate
