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 PROPOSED RESEARCH WILL DEVELOP AN IN SITU PROCESS WHICH WILL ENHANCE THE RATE AND EFFICIENCY ASSOCIATED WITH THE BIODEGRADATION OF HYDROPHOBIC ORGANIC CHEMICALS AT MILITARY INSTALLATIONS AND SUPERFUND SITES. RESEARCH ACTIVITIES WILLFOCUS ON IDENTIFICATION OF CHEMICAL OR BIOLOGICAL EMULSIFIERS (SURFACTANTS) WHICH WILL ENHANCE THE BIO-AVAILABILITY OF SUCH PETROGENIC WASTE AS CREOSOTE, COAL TARS, ...

This Phase I project involves the development of a portable system for the analysis of trace metals in aqueous solutions based on an innovative disposable multi-element nanoband electrode sensor. The system will be capable of real-time detection of a variety of heavy metals in aqueous solutions, including Zn, Cd, Pb, Cr, Cu, and Hg with a 100 ppb detection limit. The system also will be capable ...

THERE ARE NUMEROUS INDUSTRIAL PROCESSES REQUIRING THAT MATERIAL BE HEATED AND THEN SUBSEQUENTLY COOLED. IF MOST OF THIS HEAT IS RECOVERED AND RECYCLED TO THE OVEN, THE NET POWER INPUT TO THE OVEN COULD BE SUBSTANTIALLY REDUCED. THE KEY TO ACCOMPLISHING THIS IS AN INCREASE OF THE HEAT TRANSFER COEFFICIENT BETWEEN GAS AND MATERIAL SO THAT THE HEAT EXCHANGERS ARE RESASONABLY COMPACT. SIMPLE EXPERIMEN ...

RINSE WATER AND OTHER AQUEOUS WASTES FROM METAL FINISHING OPERATIONS PRESENT A DISPOSAL PROBLEM BECAUSE OF THEIR HEAVY METAL AND AGGRESSIVE CHEMICAL CONTENT. GENERALLY, THESE WASTES ARE TREATED CHEMICALLY TO PRECIPITATE THE METALIONS AS OXIDES OR HYDROXIDES. THIS TREATMENT IS COSTLY BECAUSE IT INVOLVES THE ADDITION OF CHEMICALS, DISPOSAL OF SLUDGE WITH LOSS OF VALUABLE METALS, AND LOSS OF THE HIGH ...
