Effects of Molecular Oxygen and pH on the Adsorption of Aniline to Activated Carbon
This paper examines the influence of molecular oxygen and pH on the adsorption of aniline to F-300 Calgon Carbon. Molecular oxygen increased the adsorptive capacity of GAC for anilines...

The Evaluation of Empty Bed Contact Time on the Biodegradation of Pentachlorophenol using an Anaerobic GAC Fluidized Bed
The objective of this research is to evaluate the effects of decreasing the empty-bed contact time (EBCT) on pentachlorophenol and its intermediates utilizing an anaerobic granular activated...

Activated Carbon as a Catalyst for Polymerization of Phenolic Compounds
Previous studies by the principal investigator showed that the increase in the adsorptive capacity of activated carbon for phenolic compounds can be attributed to polymerization (oxidative...

Carbon Isotopic Data from Test Hole USW UZ-1, Yucca Mountain, Nevada
Rock-CO2-gas analyses in test hole USW UZ-1 at Yucca Mountain indicate that gas movement in the unsaturated zone is likely through a dry-fracture...

Carbon-14: Some Evidence of Migration and Experiments on Immobilisation
Carbon-14 that is produced in nuclear reactors by reactions on C, N and O is one of the most biologically dangerous nuclides that are subject to global dispersion (H-3, 85-Kr, 129-I)....

Diffusion of Carbon Dioxide Through Layers of the Unsaturated Zone at Yucca Mountain
The estimation of diffusive transport of gases through tuffs is important in order to asses the Yucca Mountain as an environmentally safe and acceptable repository for spent fuel and high-level...

Organic Carbon Input in Shallow Groundwater at ÄSPÖ, Southeastern Sweden
The variation in carbon and oxygen isotopes in calcite fissure fillings and dissolved carbonate from shallow groundwaters has been examined at Aspo, southeastern Sweden. The shallow water...

Late Quaternary History and Uranium Isotopic Compositions of Ground Water Discharge Deposits, Crater Flat, Nevada
Three carbonate-rich spring deposits are present near the southern end of Crater Flat, NV, approximately 18 km southwest of the potential high-level waste repository at Yucca Mountain....

Corrosion Life-Time Assessment of Carbon Steel and Stainless Alloys for Geological Disposal Facility
The disposal facility for radioactive wastes, requires long-term integrity. Metal is considering to use as the engineered barrier which constructs the outer walls in such a facility, in...

Strontium Isotopic Evidence for a Higher Water Table at Yucca Mountain
At Yucca Mountain, calcite occurs as open-space fillings and coatings on fractures within much of the host volcanic rocks in both the saturated and unsaturated zones. Strontium isotope...

Lead Isotopic Composition of Paleozoic and Late Proterozoic Marine Carbonate Rocks in the Vicinity of Yucca Mountain, Nevada
Paleozoic and Late Proterozoic marine carbonate rocks (limestones, dolomites, and their metamorphic equivalents) cropping out in the vicinity of Yucca Mountain contain lead with an isotopic...
