EXPLOSIVES PRECURSORS QUALITATIVE AND CANTITATIVE DETERMINATION BY VALIDATED FTIR METHOD
Abstract
Taking into account the Regulation (EU) No 98/2013 of the European Parliament and of the Council of 15 January 2013 on the marketing and use of explosives precursors, which establishes harmonized rules concerning the making available, introduction, possession and use of substances or mixtures that could be misused for the illicit manufacture of explosives, with a view to limiting their availability to the general public, and ensuring the appropriate reporting of suspicious transactions throughout the supply chain, our physico-chemical laboratory was assigned to ensure the verification of the explosives precursors concentrations in suspect transports. In this regard, a new simple method was elaborated and validated, based on FTIR Spectroscopy with the ATR module for liquids. Qualitative identification method for aqueous solution of sodium perchlorate, calcium and ammonium nitrate by studying three performance parameters such as selectivity, precision, robustness and quantitative methods in various concentrations for aqueous solution of sodium nitrate, calcium nitrate, hexamine, ammonium nitrate, sodium chlorate and potassium chlorate were validated by fulfilling the performance requirements such as repeatability, reproducibility, precision, fidelity and rightness. Experimental analyses were performed and statistic parameters such as were evaluated. Bilateral scheme was performed for two precursors, sodium nitrate and hexamine, was performed and the results were beyond expectations.
