ABSTRACT
An on-site method for the determination of sulfur mustard ( SM) was developed based on pinhole shell-isolated nanoparticle-enhanced Raman spectroscopy. By using 0. 1 mol/L MgSO4 as effective agglomeration reagent, more Raman “hot spots” were induced, and thus a limit of detection for SM at 10 μg/L was achieved with a linearity of 10-1000 μg/L and an analytical enhanced factor of 1. 1×106. This method can be directly applied in the measurement of SM in environmental water samples with good sensitivity and reproducibility, and the standard addition recovery was between 88%-114%. Good differentiation of four SM related compounds, 2-chloroethyl ethylsulfide, thiodiglycol, bis-β-chloroethyl sulphoxide and bis-β-chloroethyl sulphone, was also obtained.
