The conductivity of lithium ions in polyacrylonitrile (PAN) is examined. Using the d.c. polarization method, the electric transport coefficient was observed to be less than 0.05. X-ray diffraction analysis confirms that PAN-LiClO 4 has an amorphous structure. Fourier-transform infrared spectroscopy results indicate that Li + ions form bonds not only with the C N groups of the PAN,...
This study investigates the particle-bound PAHs and metal content in the vicinity of petrochemical complex. Field measurement data indicate that the airborne concentration of particle-bound PAH correlated strongly with emission sources in the petrochemical industrial park. Concentration of particulate matter at various sampling locations had been influenced by road-dust entrainment rather than by...
