Photo-assisted electrochemical detection (PAED) following HPLC-UV for the determination of nitro explosives and degradation products

Enhanced bioremediation of RDX and Co-Contaminants perchlorate and nitrate using an anaerobic dehalogenating consortium in a fractured rock aquifer

“…RDX and its potential daughter products and perchlorate were analyzed at UMBC. The analytical method developed for RDX and intermediates, which allowed the use of small sample volumes, used high performance liquid chromatography with ultra-violet absorbance and photo-assisted electrochemical detection (Fedorowski et al, 2011(Fedorowski et al, , 2012. RDX metabolites analyzed by this method included MNX, DNX, TNX, and MEDINA; detection limits were <0.001 mg/L, except for a detection limit of <0.010 mg/L for MEDINA.…”

A novel electrochemical sensor for nitroguanidine determination using a glassy carbon electrode modified with multi-walled carbon nanotubes and polyvinylpyrrolidone

“…16 For this reason, several methods have been developed for the quantification of NG in environmental samples such as acidimetry or alkalimetry (in anhydrous solvents), high-performance liquid chromatography (HPLC), gas chromatography (GC), Raman and infrared (IR) spectroscopy, high-performance thin layer chromatography (HPTLC), and fluorescence and chemiluminescence spectroscopy. [17][18][19][20][21][22][23][24][25][26][27][28] Currently, there are no standard methods for making an accurate analysis of insensitive munition compounds (such as NG) in environmental matrices. 29 Most of these methods are complicated and relatively expensive, time-consuming, not very sensitive (due to the thermal instability and high polarity of these compounds), and lack specificity.…”
