Interfacial Radiolysis Effects in Tank Waste Speciation

Chemical Speciation of Strontium, Americium, and Curium in High-Level Waste: Predictive Modeling of Phase Partitioning During Tank Processing

Speciation of heavy metals in coastal water of Qeshm Island in the Persian Gulf

Fuel storage tanks are one of the main sources of water pollution as well as loss of crude oil and oil products in refineries.  In the process of utilization of these tanks, considerable amounts of hydrocarbons may find their way into the coastal water, which eventually lead to loss of valuable hydrocarbons. Oil type, climatic condition and characteristics of oil tanks are among the main variab...

اثر کود فسفره زیستی و بسترهای مختلف کاشت بر برخی صفات کمی و کیفی گیاه شمعدانی ‌پیچ((Pelargonium peltatum

Application of bio-fertilizers and organic compounds is a way to reduce the use of chemical fertilizers. In order to study the effects of organic compounds and phosphate bio-fertilizer on some quantitative and qualitative attributes of ivy geranium (Pelargonium peltatum), a factorial experiment based on randomized complete blocks design (RCBD) was carried out using two factors including phospha...

Dynamic Effects of Tank Waste Aging on Radionuclide-Complexant Interactions

The overall objective of this project is to provide a scientific basis for safely processing complexant-containing high-level tank wastes for disposal. Our key goals are to identify methods for preparing realistic complexant-containing tank waste simulants, and to use those simulants to determine the relative importance of organic complexants and their breakdown products on the partitioning of ...

Effects of Organic Base Chemistry on Interfacial Tension, Wettability, and Capillary Pressure in Multiphase Subsurface Waste Systems

The presence of surfactants may have profound effects on the transport of organic contaminants in multiphase systems. It is a common practice, however, to model the subsurface migration of liquids independently of the aqueous phase composition. As such, transport in these systems may not be adequately characterized. This study investigates the impact of pH on interfacial tension, wettability, a...
