Application of neural network calibrations to an halide ISE array

The Neural Network (NN) technique was applied to the calibration of an ion selective electrode (ISE) array comprising a bromide selective electrode, t wo chloride ISEs and one thiocyanate ISE. The measured samples were synthet ic mixture solutions of chlorides and bromides in concentration ranges such that interference;occurs, The NN method allowed to perform the calibration without estimating the coefficients of the Nikolskii-Eisenman theoretical relation. Only the determination of bromide was detailed. The results obtai ned using this method were better than those obtained using linear multivar iate calibration methods. (C) 2000 Elsevier Science B.V.
