Studies from Urmia University Yield New Information about Nanoparticles (Gas chromatographic detection of some nitro explosive compounds in soil samples after solid-phase microextraction with carbon ceramic copper nanoparticle fibers)

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Nanoparticles. According to news reporting originating in Orumiyeh, Iran, by NewsRx journalists, research stated, "In this research, a new solid-phase microextraction fiber based on carbon ceramic composites with copper nanoparticles followed by gas chromatography with flame ionization detection was applied for the extraction and determination of some nitro explosive compounds in soil samples. The proposed method provides an overview of trends related to synthesis of solid-phase microextraction sorbents and their applications in preconcentration and determination of nitro explosives."

The news reporters obtained a quote from the research from Urmia University, "The sorbents were prepared bymixing of copper nanoparticles with a ceramic composite produced by mixture of methyltrimethoxysilane, graphite, methanol, and hydrochloric acid. The prepared sorbents were coated on copper wires by dip-coating method. The prepared nanocomposites were evaluated statistically and provided better limits of detection than the pure carbon ceramic. The limit of detection of the proposed method was 0.6 mu g/g with a linear response over the concentration range of 2-160 mu g/g and square of correlation coefficient >0.992. The new proposed fiber has been demonstrated to be a suitable, inexpensive, and sensitive candidate for extraction of nitro explosive compounds in contaminated soil samples."

According to the news reporters, the research concluded: "The constructed fiber can be usedmore than 100 times without the need for surface generation."
