Detection of TNT wastewater by the molecular imprinted porous membrane

Abstract

In this paper, the preparation scheme of TNT molecularly imprinted porous film and the scheme of TNT identification and detection in wastewater are designed by means of molecular imprinting technology. The molecularly imprinted porous film material was prepared by the self-assembly method, and the TNT residue adsorption was detected by a UV-visible spectrophotometer. The concentration of TNT waste liquid was calculated by absorbance, and the effect of the deviation of ultraviolet spectra of different contents of TNT waste liquid was discussed. The results show that the molecularly imprinted films have high adsorption and specific recognition effect on TNT, which can be used for rapid and sensitive detection of TNT in the waste liquid.
