Aqueous modelling of chemical speciation in simulated lung fluid (SLF) enables a better understanding the underlying factors that influence metal(loid) inhalation bioaccessibility from airborne particulate matter. Such an approach can be used to supplement experimental techniques are integral health risk assessment exposure by inhalational routes. In this paper, we modelled aqueous chemistry pa...

Vast majority of past studies that have been conducted on controlled salinity water flooding (CSWF) use diffuse layer model (DLM) calculates only the surface potential, which can be significantly different from ?-potential interface. Importantly, stability water-film (between oil and rock surface) dictates ultimate recovery is related to ?-potential. As such, using DLM calculated potential (dir...

Finding cost-efficient ways of increasing oil production with a low carbon footprint is the new challenge for petroleum industry that wants to meet net-zero emission goals by 2050. Smart water injection an EOR process increases and delays breakthrough wettability alteration. Seawater smart in chalk reservoirs, being especially effective at high temperatures. Different studies have shown effecti...

Summary Several laboratory experiments demonstrated that the use of sodium hydroxide could increase solution pH and reduce adsorption anionic surfactants. However, a better understanding rock-oil-brine interactions their effect on surfactant during alkaline-surfactantpolymer (ASP) flooding is needed for realistic representative estimations levels. Therefore, this study presents novel approach t...

Radionuclides are inorganic substances, and the solubility of substances is a major factor affecting disposal radioactive waste release concentrations radionuclides. The degree determines whether nuclide source migrates to far field site. Therefore, most effective method for retarding radionuclide migration reduce in aqueous geochemical environment subsurface systems. In order assess performanc...

The calculation of a reliable temperature dependent dolomite solubility product constant (Ksp?dol) has been the subject much research over last 70 years. This study evaluates log10(aCa2+/aMg2+) values using PHREEQC (Pitzer approach) for screened subset (n = 11,480) formation waters in U.S. Geological Survey National Produced Wate...

background and objectives: the mobility, bioavailability and environmental fate of heavy metal ions in soil are controlled by sorption onto soil minerals and solid organic matter. the sorption is strongly affected by the presence of various low-molecular-weight organic acids. the main objective of this study was to investigate the effects of oxalic acid on sorption of cd on clay fraction of a s...
