Abstract
⺠We introduce a simple, sensitive, selective and low cost procedure for direct spectrophotometric determination of melamine in milk samples by applying RAFA to pH gradual change-UV spectral data (pH-spectra). ⺠We recorded the changing spectra and obtained the bilinear matrix of pH-spectra. Based on these data, the concentration of melamine in samples could be predicted by RAFA with satisfactory results. ⺠The complicated pre-separation operation is not needed. ⺠The approach is simple to producing second order data. ⺠The apparatus required in this method is easily obtainable.
