title: [Simultaneous spectrophotometric determination of mixed colorants by artificial neural network].
abstract: The back propagation artificial neural network was applied to process spectrophotometric data of mixed colorants. By optimizing the network structure and parameters, the predication accuracy was enhanced. The method was used for simultaneous determination of mixed colorants in synthetic samples and drinks on sale with satisfactory results. Therefore, the artificial neural network may provide a new approach to determine the mixed colorants is drinks by spectrophotometry without any preliminary chemical separation.
