Molecularly imprinted polymers for detection of explosives In gas phase approach for the detection of TNT in cargo containers

In this work, adsorption properties of TNT molecularly imprinted polymers (MIPs) with different functional monomers are characterized using Langmuir and Freundlich isotherm. Affinity constants and pre-exponential factors are calculated for the two models. Langmuir model is applicable in gas phase adsorption on MIPs which is different from adsorption in liquid phase. The MIPs investigated here use TNT as template and acryl amide (AA), methacrylic acid (MAA) and methacrylamide (MAAM) as functional monomers.
