Title of the project

VOLTAMMETRIC DETECTION OF NITRO-EXPLOSIVE COMPOUNDS USING HYBRID DIAMOND-GRAPHENE SENSORS: FIELD MONITORING OF EMERGING CONTAMINANTS IN THE BALTIC SEA REGION

 

NOR/SGS/NITROsens/0011/2020-00

  • Project timeline: 01.09.2021 – 01.09.2023
  • The research leading to these results has received funding from the Norway Grants 2014-2021 via the National Centre for Research and Development as part of the SMALL GRANT SCHEME Call competition for PLN 909,935 
 
the goal of the project

The main project objective is to develop a novel electrochemical sensing platform – NITROsens for nitro-explosive compounds detection in both sea and freshwater. The functional nanostructured carbon sensing electrode will be designed, allowing to achieve enhanced sensitivity towards high-energetic nitro-compounds. The sensor will make it possible to quickly confirm the presence of explosive compounds in the aquatic environment. 

Impact

1. CONTROL OF THE CONCENTRATION OF NITRO-EXPLOSIVE COMPOUNDS IN THE BALTIC SEA

The worldwide use of nitro-explosives in the military and industrial applications has led to widespread environmental contamination. Only after World War I and II in the Baltic Sea, vast amounts of nitro-explosives was dumped, including highly toxic 2,4,6-trinitrotoluene (TNT) and 1,3,5-trinitro-1,3,5-triazine (RDX). Only in the vicinity of Germany, there are 1.6 million metric tons of sunken conventional munition explosives. Over time, metal shields in which explosives have been deposited begin to corrode, which results in increasing uncontrolled emissions of these pollutants into the environment. From these reasons, nitro-explosives and their decomposition products are widespread in the environment, especially in marine and inland water. However, the detection of conventional explosives in natural ecosystems is still an analytical challenge.

2. DEVELOPING AN INNOVATIVE SENSORY PLATFORM FOR THE FAST DETECTION OF NITRO-EXPLOSIVE COMPOUNDS

In this project, we propose a novel electrochemical sensing platform – NITROsens for rapid nitro-explosive compounds detection in both sea and freshwater. The limit of detection of NITROsens platform will be below the lifetime health advisory limit of nitro-explosive in drinking water, i.e. 2.0 ppb. The sensor will make it possible to quickly confirm the presence of explosive compounds in the aquatic environment. Hence, it can be successfully used for screening measurements to estimate environmental pollution with high-energetic nitro-compound. The sensor can also be used to assess the degree of leakage of explosives from the dumped after World War I and II barrels.
