An analytical method for the simultaneous determination of organochlorine pesticides, PCBs, PAHs, phthalates, chloroaromatics, phenolics, phenoxy acids and other base/neutral compounds in sewage sludge is described. Spiked sewage sludge samples were extracted with a mixture of dichloromethane/diethyl ether under basic and acidic conditions. The combined extracts were fractionated via gel permeation...
The infrared emittance and transmittance spectra of a chemical vapor-deposited diamond substrate were determined at 4.2, 77 and 295 K. The multiphonon region was analyzed under varying degrees of spectral resolution. No variance in spectral properties over this temperature range was observed beyond measurement uncertainty. The refractive index of the material was determined in the 3-21 micron spectral...
