AB  - The study of the electrochemical reduction on acetonitrile modified platinum electrode and determination of trinitrotoluene (TNT) in neutral solution by simple galvanostatic technique is presented here. The obtained potential-time responses on the applied constant cathodic current pulses showed two potential transitions before achieving the steady-states, referring to the multi-step reduction process of nitro groups in TNT molecule. The calibration curves of the dependence of the square root of the first transition time (τ 0.5) on the TNT concentration were linear in the ranges 4.4 – 303.8 μM and 0.09 – 4.40 μM for applied constant current of 0.1 mA. The detection limit was 0.09 μM. The method was tested in the river water. The results indicated the sensitivity of the galvanostatic method for TNT determination in the environmental samples. From the first transition on the E-t curves the characteristics important for the understanding the mechanism of the reduction process were obtained. It was found that four electrons are involved in the reduction process of the first nitro group, indicating that the reduction product in a neutral electrolyte is hydroxylamine.

AB  - The electrochemical reduction of 2,4,6-trinitrotoluene (TNT) was investigated by cyclic voltammetry on a platinum electrode in aqueous sodium chloride solutions with acetonitrile containing different concentrations of TNT. The obtained cyclic voltammograms showed three distinct reduction peaks in the potential range of -0.45 to -0.8 V (vs. an Ag/AgCl (3 M KCl) reference electrode), which refer to the multi-step process of TNT reduction. The calibration curves of the dependence of the first peak current on the TNT concentration were linear in the ranges 4.4-638.4 μM and 0.11-4.40 μM for two different scan rates, 200 mV s-1 and 20 mV s-1, respectively. The detection limit was 0.11 μM. Acetonitrile chemisorption on Pt surface took place and caused thus modified platinum electrode to exhibit an electrochemically stabile behaviour. Hence, a very high reproducibility over a prolonged time and voltammetric cycling was provided for using a Pt wire that is easy to handle as a suitable material for TNT sensing. Additionally, it was confirmed by testing the acetonitrile modified Pt wire for TNT detection in river water. © 2010 Elsevier B.V. All rights reserved.

AB  - This work studies the introduction of cleaner production (CP) in the tank farm of the Pancevo Oil Refinery. From 2003 to 2008, substantial investments in storage technology and equipment were made in order to minimize the emissions of volatile organic compounds (VOCs). This article analyzes the effects of the CP activities using a model of tank farm emissions before and after reconstruction. US EPA TANKS software was used in order to develop a comprehensive model of the tank farm emissions. The year 2006 was accepted as representative for the analyses and related technical and production data as well as meteorological information were employed in the development of the model. The results show that the total VOC emissions were 37.6% lower after reconstruction and that the emissions of the major pollutant benzene were decreased by 62.7%. The effects of the CP activities were analyzed through the reduction of ecological damage, elements related to the operating costs, liability issues and the company's image. Future tank farm reconstruction activities in the Oil Refinery, Pancevo were proposed and their environmental effects predicted. An indicator of the expected decrease in VOC pollution was developed and quantified, with the aim of its use for quick calculations in similar cases. © 2010 Elsevier Ltd. All rights reserved.
