The fluorescence spectra of melamine milk solution are measured under the UV light excitation.A model(WT-RBFNN) that combines wavelet transform(WT) and radial basis function neural network(RBFNN) is proposed to determine the melamine concentration in milk by fluorescence spectroscopy.The trained RBFNN is employed to determine the six kinds of samples melamine milk solution concentration,the relative error of the results are 1.19%,2.99%,1.06%,1.43%,2.12% and 3.83%,respectively.The results show this method ca...
