“…3a and 3b). There For TATP, LODs reported by GC-MS ranged from 0.1 -5 ng [25,26], LODs reported by using Ion Mobility Spectrometry (IMS) ranged from 800 -1900 ng [27]. The lowest LOD for H 2 O 2 by chemiluminescence using Cu 2+ as a catalyst was reported at 0.3 µM [28], which is slightly lower than the 0.5 µM obtained in this work.…”

“…Triacetone triperoxide (TATP) is a primary high explosive that has been used by terrorist organizations 1, 2. Unlike most secondary high explosives intended for military and industrial applications, TATP has a high vapor pressure,3 and may readily be detected through vapor sampling and analysis techniques 4–6…”

Sonochemical synthesis of platinum nanoparticles (Pt NPs) in formic acid solutions and pure water was investigated using a 20 kHz ultrasonic irradiation. The obtained results gave new insights on the underneath Pt(IV) reduction mechanism in formic acid media under argon and in pure water under Ar/CO atmosphere. It was shown that in pure water sonochemical reduction of platinum ions occurs by hydrogen issued from homolytic water molecule split. Pt(IV) ion reduction appears to be a very slow process under argon atmosphere in pure water due to formation of oxidizing species like OH radicals and H(2)O(2) leading to reoxidation of intermediate Pt(II) ions. Sonochemical reduction is accelerated manifold in the presence of formic acid or Ar/CO gas mixture. Solution and gas-phase analyses reveal that both CO and HCOOH act as OH(.) radical scavenger and reducing agent under ultrasonic irradiation. Their ability to reduce platinum ions at room temperature is enhanced due to the local heating in the liquid shell surround the cavitation bubble. An innovative synthesis route for monodispersed Pt NPs in pure water without any templates or capping agents in the presence of Ar/CO gas mixture is then proposed. Obtained Pt NPs within the range of 2-3 nm exhibited a strong stability towards sedimentation in water. Since Ar/CO atmosphere is the only restriction of the process, this procedure can be applied in various media and is also compatible with a large array of experimental conditions.

“…Solid phase microextraction (SPME)-GC-MS method having fast analysis time and simple sample preparation to analyze TATP with detection limits being 5 ng has been reported (Kende et al, 2008). Same method has been used to analyze chemical degradation products of TATP after treatment with different acids and storage: the results indicated that both rate of degradation and the products formed are dependent from the acid.…”

In recent years, explosive materials have been widely employed for various military applications and civilian conflicts; their use for hostile purposes has increased considerably. The detection of different kind of explosive agents has become crucially important for protection of human lives, infrastructures, and properties. Moreover, both the environmental aspects such as the risk of soil and water contamination and health risks related to the release of explosive particles need to be taken into account. For these reasons, there is a growing need to develop analyzing methods which are faster and more sensitive for detecting explosives. The detection techniques of the explosive materials should ideally serve fast real-time analysis in high accuracy and resolution from a minimal quantity of explosive without involving complicated sample preparation. The performance of the in-field analysis of extremely hazardous material has to be user-friendly and safe for operators. The two closely related ion spectrometric methods used in explosive analyses include mass spectrometry (MS) and ion mobility spectrometry (IMS). The four requirements-speed, selectivity, sensitivity, and sampling-are fulfilled with both of these methods.
