Abstract: The invention discloses a photoelectric chemical analysis method adopting a molecular imprinting functionalization modified electrode, relates to a molecular imprinting technology-based preparation method of a high-selectivity TiO2NTs modified electrode, and also relates to a method for high-selectivity and high-sensitivity detection of endocrine disrupting chemicals especially such as 2,4-dichlorophenoxyacetic acid (2,4-D) having no electrochemical activity by the high-selectivity TiO2NTs modified electrode as a photo anode. Compared with the prior art, the molecular imprinting technology-based preparation method creatively utilizes a molecularly imprinted polymer in selective modification of a photoelectric sensing electrode so that selectivity and detection sensitivity of an electrode are improved greatly; the interference caused by multiple concomitant micro-molecules is eliminated; a magnitude of a detection limit reaches to 10<-8>mol/L<-1>; the molecular imprinting functionalization modified electrode is stable; and the photoelectric chemical analysis method for detection has good reappearance.
