This project addresses the development of diode-laser-based continuous-emissionsmonitors (CEMs) to meet the emissions monitoring requirements imposed on a widerange of industries by Federal and state clean air regulations. The overridingobjective is the development of new, highly reliably instrumentation that hassubstantially lower long term operating and maintenance costs than existinginstrument ...

In order for plastics recycling to be a viable alternative in the long term, the recycled resins must be competitive with virgin resins both in terms of economics and purity. Current processing technologies utilize either hand sorting or automated sorting on the bottle level. However, there are many sources of contamination other than whole bottles, which will remain in the stream using whole bot ...

COMMON CAUSE FAILURE ANALYSIS (CCFA) IS AN IMPORTANT ELEMENTOF A COMPLETE PROBABILISTIC RISK ASSESSMENT (PRA) SINCE COMMON CAUSE FAILURE IS OFTEN A DOMINANT FACTOR IN THE RISK POSED TO PUBLIC HEALTH AND SAFETY FROM NUCLEAR POWER PLANT ACCIDENTS. A MAJOR PROBLEM ASSOCIATED WITH PERFORMING A CFFA IS THE ABSENCE OF SUPPORTING QUALITATIVE OR QUANTITATIVE COMPONENT FAILURE DATA. EXTENSIVE AMOUNTS OF CO ...

CONTAMINATION OF GROUNDWATER BY TRICHLOROETHYLENE AND OTHER VOLATILE HALOGENATED SOLVENTS REPRESENTS A SERIOUS THREAT TO THE NATION'S DRINKING WATER. CURRENT TREATMENT TECHNIQUES FOR CONTROLLING SUCH CONTAMINATION ARE LIMITED TO AERATION, ADSORPTION, AND LINKING. A PROMISING ALTERNATIVE IS PHOTOCHEMICAL OXIDATION, BUT THIS PROCESS IS AS YET UNOPTIMIZED, POORLY UNDERSTOOD, AND LARGELY LIMITED. PHOT ...

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 ...

Industrial wastewater containing toxic waste compound and metal ions pose manyproblems of disposal. The most generally used method of removing metalcontaminants is lime treatment to precipitate metals as hydroxides. The metalis not normally recovered resulting in the need for sludge disposal. The costof sludge disposal plus fewer available disposal sites makes that methodincreasing less attract ...
