Electrochemical sensor for nitroaromatic type energetic materials using gold nanoparticles/poly(o-phenylenediamine–aniline) film modified glassy carbon electrode

Electrochemical behavior and voltammetric determination of some nitro-substituted benzamide compounds

“…As can be seen in Table 4, the linearity range is wider than that for the DP voltammetric determination of nitrofurantoin (NF) at a mercury meniscus modified silver solid amalgam electrode (2-100 µ M), 36 determination of 2-amino-6-nitrobenzothiazole (ANBT) at a silver solid amalgam electrode modified by a microcrystalline natural graphite polystyrene composite film (0.2-10 µ M), 33 amperometric detection of nitrophenol (NP) at a porous copper modified PGE (50-850 µ M), 38 and cyclic voltammetric determination of trinitrotoluene (TNT) (2.5-40 and 40-120 mg L −1 ) and dinitrotoluene (DNT) (2-40 and 40-140 mg L −1 ) . 30,31 The sensitivity of the proposed method is higher than that of determination of NF, 36 ANBT and 5-nitrobenzimidazole (5-NBIA), 33 NP, 38 TNT, and DNT. 30,31 Moreover, it is comparable to that obtained with determination of niclosamide at a PGE 39 and determination of aromatic nitro compounds (nitrobenzene, TNT, and DNT) at a Pd nanoparticle graphene modified GCE.…”

Fe‐enriched Clay‐coated and Reduced Graphene Oxide‐modified N‐doped Polymer Nanocomposite: A Natural Recognition Element‐based Sensing Electrode for DNT

“…Nitro‐explosives inherently possess electroactive characteristics because of the reducible nitro groups present in their structures . Hence, electrochemical measurements of nitro‐aromatic compounds are relatively faster and can provide higher sensitivity and lower detection limit over a wide linear concentration range than the other measurement techniques such as mass spectrometry, electron capture detector, and ion mobility spectrometry .…”

Graphene based nanosensor for aqueous phase detection of nitroaromatics

“…14 Several polymeric systems were employed for the detection of nitroaromatics using physical, structural and electronic interactions between analyte and polymeric material. 26,27 Primary concern in developing new sensors is to collect adequate amount of recognition/binding element in the sensor probe. In this aspect, molecularly imprinted polymers possess various advantages such as varying selectivity and low cost.…”
