Methods for 90 S r in soil by Cherenkov counting and liquid scintillation spectrometry

Electrochemical determination of insensitive munition constituents 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) using gold nanoparticle/carbon nanotube‐modified pencil graphite electrode in groundwater sample

Propellants, Explosives, Pyrotechnics

For the electrochemical detection of nitrotriazolone (NTO), multiwalled carbon nanotubes (MWCNT) ... more For the electrochemical detection of nitrotriazolone (NTO), multiwalled carbon nanotubes (MWCNT) and gold nanoparticles have been combined to generate nanocomposites. Electrochemical analysis and surface characterisation using scanning electron microscopy (SEM) and energy dispersive X‐ray (EDX) spectroscopy techniques were used to confirm the presence of gold nanoparticles on MWCNT. The electrochemical behavior of NTO at the modified pencil graphite electrode in the pH range of 2.0–10.0 (0.04 M Britton‐Robinson buffer solution) was evaluated using cyclic (CV) and differential pulse voltammetry (DPV).The suggested electrochemical sensor displayed a quick reaction to NTO with an optimal set of experimental parameters, a linear calibration curve spanning 30 to 1500 nM, and a detection limit of 22.6 nM. Using the differential pulse voltammetry technique, the usefulness of the MWCNT/AuNPs, and PGE for the determination of NTO in groundwater was evaluated.

Characterization and properties of a new insensitive explosive co-crystal composed of trinitrotoluene and pyrene

A new energetic co-crystal of trinitrotoluene (TNT) and pyrene (PYRN) with a 1:1 molar ratio was ... more A new energetic co-crystal of trinitrotoluene (TNT) and pyrene (PYRN) with a 1:1 molar ratio was prepared by a slow solvent evaporation technique. Co-crystal physicochemical properties have also been examined using optical microscopy, powder X-ray diffraction, single crystal X-ray diffraction, and differential scanning calorimetry. The results of single-crystal X-ray diffraction and non-covalent interaction calculations showed that non-covalent interactions (donor-acceptor π-π interaction) govern the structures of the TNT: PYRN co-crystal. The experimental and theoretical outcomes supported each other in the study. Thermal stability, impact sensitivity, and detonation performance of the co-crystal were investigated. DSC measurement indicates that the co-crystal has a melting point of 167°C and a decomposition temperature of 293°C, indicating outstanding thermal stability. The co-crystal was found to be less impact-sensitive than TNT using the BAM fall hammer instrument. Furthermore,...

Electroanalytical Determination of Ziram by Differential Pulse Voltammetry with Reduced Graphene Oxide/Gold Nanoparticles Modified Glassy Carbon Electrode

Acta Chimica Slovenica

The graphene oxide (GO) was synthesized using a modified Hummer’s method. A composite sensor consisting of gold nanoparticles (AuNPs) and reduced graphene oxide (RGO) was electrochemically fabricated on a glassy carbon electrode. The nanocomposite was evaluated utilizing scanning electron microscopy (SEM). Cyclic voltammetry was used to illuminate the modified sensor’s electrochemical properties at each stage of the modification. The suggested sensor was demonstrated good analytical performance to determine ziram pesticide in water and peach juice, including a very low detection limit, a large linear range, and a low RSD.

Samples were collected by using duplicate portion sampling technique and dried by freeze dryer after their homogenization process. The method used in the 90 Sr analysis is based on the separation of the daughter 90 Y at equilibrium with 10% di(2-ethyl-hexyl)phosphoric acid (HDEPH) in toluene and Cherenkov counting by a liquid scintillation spectrometer (LSS). 14 C activity concentration is determined by the combustion of the sample in an oxygen atmosphere to 14 CO2, absorption of 14 CO2 by special reagent, mixing with the scintillator and counting in liquid scintillation spectrometer. 40 K, 134 Cs and 137 Cs activity concentrations were measured by high purity germanium detectors in gamma spectrometer. An annual effective dose caused by these radionuclides was estimated usi...

Po-210 decays to stable lead with a physical half-life of 138 days. This means that after 138 days, only half o f the radioactivity originally present is left. Different methods can be used to measure Po-210 according to the objectives o f the measurement. Generally, the greater the precision and sensitivity needed, the longer the process w ill take because o f the need for chemical processing to separate and concentrate polonium and, to allow time for a sufficient number o f radioactive decays to take place. The main objective o f this work w as to investigate the suitability o f liquid scintillation spectrometry to provide a fast analytical procedure for the determination o f Po-210 in urine samples. LSS was used as screening method for the preliminary analysis o f Po-210 in 103 urine samples collected from the passengers o f suspicious British Airway...
