Decontamination of 2 chloro ethyl phenyl sulphide using mixed metal oxide nanocrystals

Abstract

Decontamination reaction of 2 chloro ethyl phenyl sulphide (2-CEPS), a surrogate of sulphur mustard, was studied on nanocrystals of AP-Al₂O₃, AP-Al₂O₃-Fe₂O₃, AP-Al₂O₃-V₂O₅ and AP-Al₂O₃-CuO by using gas chromatography, gas chromatog­raphy-mass spectrometry and infrared spectroscopy techniques. Decontamination of 2-CEPS resulted via hydrolysis, oxidation and formation of surface bound alkoxides on AP-Al₂O₃-V₂O₅, whereas on AP-Al₂O₃, AP-Al₂O₃-Fe₂O₃ and AP-Al₂O₃-CuO, de­contamination of 2-CEPS resulted by hydrolysis and formation of surface bound alkoxides. Reaction of 2-CEPS on AP-Al₂O₃, AP-Al₂O₃-Fe₂O₃, AP-Al₂O₃-V₂O₅and AP-Al₂O₃-CuO exhibited pseudo first order behavior. AP-Al₂O₃-Fe₂O₃, AP-Al₂O₃-V₂O₅and AP-Al₂O₃-CuO nanocrystals exhibited superior decontamination properties than AP-Al₂O_3.
