Radioactive "mixed" waste contains radionuclides and varying quantities of semivolatile and/or volatile organics, some or all of which may be named specifically by the RCRA. They are presently stored above-ground at greatcost to the user. Analytical

The regulatory semivolatile organic compounds present in radioactive aqueous waste samples are extracted and concentrated in a small-scale version of a standard EPA procedure normally used for ground waters. Decontamination is sufficient to permit an

The mutagen, 2-aminonaphthalene, which is the dominant aromatic amine species in several fossil fuels, may be isolated readily by using a sequential high-performance liquid chromatographic procedure. An initial isolation is achieved on a semi-prepara
