Plasticizer diisononyl phthalate reacts with Fluorescent Pink reagent in aqueous solution,making the fluorescence intensity of Fluorescent Pink enhance.The degree of fluorescence enhancement shows a good liner relationship with the content of diisononyl phthalate in certain range,so we establish a new fluorescence spectrometry for the determination of plasticizer diisononyl phthalate.The regression equation is F=-2.5+134.6C,correlation coefficient r=0.999 5,the linear range is 5.0×10-7-2.0×10-5 mol/L,relati...
