Resolution of GC-MS data of complex PAC mixtures and regression modeling of mutagenicity by PLS

Article Abstract:

A variety of different polycyclic aromatic compounds (PACs) can be found in organic extracts of exhaust particles that are generated by combustion of fossil fuels. It is hard to quantify and predict the combined mutagenic or toxic effects of the PACs. The following paper discusses a strategy to predict the mutagenicity of PAC mixtures from mass spectrometry (GC-MS) - gas chromatography.

Catalytic reduction of NO with NH(sub 3) over carbons impregnated with Cu and Fe

Article Abstract:

Combustion of fuel and hyrdrocarbon wastes are two ways which nitrogen oxides are formed. One of the best ways of controlling nitrogen oxide emissions from stationary sources is the use of selective catalytic reduction (SCR) with NH(sub 3). The following experiment undertakes the examination of SCR of nitrogen oxides with NH (sub 3) over carbons impregnated with Fe and Cu.
