Developments in on-site spent solvent recovery have implications for reducedenvironmental pollution in the dry cleaning, furniture and paint manufacturingindustries as well as in a range of commercial services. Effluents from solventrecovery operations include fugitive emissions, vent stack gases and water/solvent mixtures. At present, the scale of solvent-recovery operations incertain industrie ...

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

THE DESTRUCTION OF ORGANIC HAZARDOUS WASTE BY ELECTRIC ARC PYROLYSIS HAS BEEN DEMONSTRATED TO BE TECHNICALLY FEASIBLE BY OTHERS. THE PRINCIPAL PROBLEMS LIE IN (1) THE SHORT LIFEOF THE ELECTRODES (AND RELATED STRUCTURES) DUE TO THE HIGH TEMPERATURES INVOLVED, AND (2) THE RELATIVELY HIGH COST OF THE ELECTRIC POWER NEEDED. APPLIED RESEARCH ASSOCIATES, INC. PROPOSE TO DESTROY ORGANIC HAZARDOUS WASTE B ...

SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

THE PRODUCTION OF HALOGENATED ORGANIC COMPOUNDS (HOCS) AND OF CHLOROFLUOROCARBONS (CFCS), IN THE UNITED STATES, PRODUCES ABOUT 200 MILLION POUNDS OF REFRACTORY, HAZARDOUS WASTE PER YEAR. DUE TO ITS LOW FUEL VALUE, CORROSIVITY, ANDHAZARDOUS METALS CONTENT, THE WASTE IS POORLY SUITED FOR DISPOSAL BY INCINERATION AND IS BANNED FROM DISOSAL IN LANDFILLS. PREVIOUS HAZARDOUS WASTE DISPOSAL RESEARCH, SPO ...

The Phase II work will demonstrate at pilot scale the successful recovery of antimony and iodine values from spent perfluoroalkyliodide (PFAI) catalyst. The technical feasibility of this innovation and simple recovery process was demonstrated in Phase I. This recovery process was shown to be capable of nearly 100% recovery of both antimony and iodine values without generation of hazardous air em ...

Replacements for the halocarbons banned by the Montreal Protocol will be producedby technologies which generate spent catalysts as a waste byproduct. These spentcatalysts contain tin, a valuable metal resource, in a matrix that willundoubtedly be classified as hazardous with regard to its disposal.Chemical & Metal Industries, Inc., proposed in this Phase I effort to investigatetwo alternative tec ...
