Uranium adsorption by iron modified zeolite and zeolite composite membranes.

Composite membranes incorporated with high-performance adsorbents are promising for uranium removal. The impact of speciation and ionic strength on uranium adsorption by zeolites was investigated in both static adsorption and composite membrane filtration. Zeolites with high Si/Al ratios exhibited the highest uranium adsorption capacity.

Understanding fluoride adsorption from groundwater by alumina modified with alum using PHREEQC surface complexation model.

Fluoride is recognized as a vital ion for human and animal growth because of the critical role it plays in preventing skeletal and dental problems. However, when it is ingested at a higher concentration it can cause demineralization of teeth and bones resulting in fluorosis, therefore, the production of high-adsorptive capacity material which is also cost-effective is necessary for the treatment of fluorides. In this study, aluminium foil is valorised into alumina nanoparticles.

Theoretical Modeling of the Impact of Salt Precipitation on CO Storage Potential in Fractured Saline Reservoirs.

Deep saline reservoirs have the capacity to hold large volumes of CO. However, apart from the high brine salinity, which poses an injectivity challenge, a high percentage of saline reservoirs are also fractured. The mechanisms of drying and salt precipitation and the resulting impact on CO injection are unique in fractured reservoirs.
