Abstract:   (2691 Views)
Simultaneous analysis of explosives to identify, determine the purity and eliminate environmental pollution requires rapid, simple and cheap methods. Spectrophotometries method (UV-Vis), high-field proton nuclear magnetic resonance (1H-NMR), Raman spectroscopy and near infrared (NIR) are common methods that are applicable in two ways of direct and indirect in simultaneous analysis. In this point of view, derivative Spectrum and chemometric methods as direct method, without the initial separation steps, to improve the ability to detection peaks. In indirect methods, they used by coupling to other methods. In this manner High performance liquid chromatography (HPLC) provides resolution, high selectivity and reproducibility. Also in 1H-NMR, can achieved significantly to limit of detection without the need for derivatization with various compounds. Deep-ultraviolet resonance Raman spectroscopy (DRIVER) is used to detect of trace amounts of explosives with high reliability and sensitivity and fewer errors, speed and non-destructive NIR methods also, this method has suitable for the simultaneous analysis.
