N,N'-disalicylidene-1,2-propanediamine; determination of in jp-8 jet fuel and use as ligand in ion selective electrode membrane : water activation of magnesium nickel alloy for hydrogen uptake and storage

Abstract

Alternative fuels are developed for various reasons. One reason is to simplify the number of fuels needed in combat conditions .. The military has developed an alternative fuel, JP-8 jet fuel, for use fn its aircraft, armored and personnel vehicles, and generators in combat conditions. Another reason is growing concern over the depletion of the world's fossil fuel reserves. Hydrogen has been considered an ideal alternative to fossil fuels because it is abundant, and if burned properly is environmentally friendly. JP-8 contains the metal deactivator N,N'-disalicylidene- 1,2-propanediamine (DSPA) to reduce the catalytic activity of dissolved copper, thus increasing the thermal stability of the fuel. A method for determination of DSPA in JP-8 jet fuel, and a cation-responsive 1electrode system that incorporates DSPA in an ion selective electrode membrane have been developed. Determination of DSPA in JP-8 with aqueous and non-aqueous systems has been investigated. Results obtained using high pressure liquid chromatography, and UV/visible spectrophotometry are included. Electrodes have been produced that can be conditioned for a particular ion. Preparation method, electrode response, and selectivity studies are included. Activation of magnesium nickel alloy for hydrogen uptake and storage has been the focus of intensive investigations.An inexpensive and rapid activatipn procedure for magnesium nickel alloy for hydrogen uptake and storage has been discovered. This process has been studied using differential scanning calorimetry, x-ray photoelectron spectroscopy, mass spectrometry, and scanning electron microscopy.
