Nitroaromatic explosives detection using electrochemically exfoliated graphene
Detection of nitroaromatic explosives is of paramount importance from security point of view. Graphene sheets obtained from the electrochemical anodic exfoliation of graphite foil in different electrolytes (LiClO4 and Na2SO4) were compared and tested as electrode material for the electrochemical detection of 2,4-dinitrotoluene (DNT) and 2,4,6-trinitrotoluene (TNT) in seawater. Voltammetry analy...
متن کاملCapacitance Properties of Electrochemically Synthesised Polybithiophene-Graphene Exfoliated Composite Films
The graphene (GR) has attracted intensive interest due to its two-dimensional and unique physical properties. In the present study, the graphene sheets were synthesized by electrochemical exfoliation of graphite in sulfuric acid solution. The polybithiophene-graphene (PbTh-GR) composite films deposited onto indium tin oxide substrate (ITO/PbTh-GR) have been prepared by the incorporation of ...
متن کاملPolymer sensors for nitroaromatic explosives detection
Several polymers have been used to detect nitroaromatic explosives by a variety of transduction schemes. Detection relies on both electronic and structural interactions between the sensing material and the analyte. Quenching of luminescent polymers by electron deficient nitroaromatic explosives, such as trinitrotoluene, may be monitored to detect explosives. Resistive sensing using carbon black...
متن کاملDetection of nitroaromatic explosives based on photoluminescent polymers containing metalloles.
The synthesis, spectroscopic characterization, and fluorescence quenching efficiency of polymers and copolymers containing tetraphenylsilole or tetraphenylgermole with Si-Si, Ge-Ge, and Si-Ge backbones are reported. Poly(tetraphenyl)germole, 2, was synthesized from the reduction of dichloro(tetraphenyl)germole with 2 equivs of Li. Silole-germole alternating copolymer 3 was synthesized by coupli...
متن کاملFluorescent Nanofilms for Nitroaromatic Explosives Detection-Promises and Challenges
Fast and sensitive detection of nitro-aromatic explosives is of vital importance for finding hidden explosives in airport luggage or mails, screening of personnel, and detection of buried landmines [1-3]. A crucial example is the detection of trace amount of 2,4,6-trinitrotoluene (TNT), which is a typical nitro-aromatic explosives [ 4-8]. Various TNT detection methods are currently available, s...
