Biosorption of metal ions by phototrophic microorganisms is regarded as a sustainable and alternative method for bioremediation and metal recovery. In this study, 12 cyanobacterial strains, including 7 terrestrial and 5 aquatic cyanobacteria, covering a broad phylogenetic diversity were investigated for their potential application in the enrichment...

In this paper, the adsorption process of copper ions on activated carbon (AC) was simulated in a column test. It was deduced that it is consistent with the pseudo-second-order model. Cation exchange was observed to be the major mechanism of Cu–AC interactions through scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDS), X-ray...

One of the crucial challenges of our time is to effectively use metal and metal oxide nanoparticles (NPs) as an alternative way to combat drug-resistant infections. Metal and metal oxide NPs such as Ag, Ag2O, Cu, Cu2O, CuO, and ZnO have found their way against antimicrobial resistance. However, they also suffer from several limitations ranging from...

Titanate nanotubes were synthesized and subjected to an ion exchange reaction with erbium salt aqueous solution to obtain titanate nanotubes exchanged with erbium (3+) ions. In order to evaluate the effects of the thermal treatment atmosphere on the structural and optical properties of erbium titanate nanotubes, we subjected them to heat treatment ...

Per- and polyfluoroalkyl substances (PFASs) have received extensive attention due to their various harmful effects. In this study, the adsorptive removal of 10 legacy and emerging PFASs by four anion-exchange resins (including gel and macroreticular resins) were systematically investigated. Our results showed that the capacities of resins absorbing...

Platinum-based catalysts are widely used for efficient catalysis of the acidic oxygen reduction reaction (ORR). However, the agglomeration and leaching of metallic Pt nanoparticles limit the catalytic activity and durability of the catalysts and restrict their large-scale commercialization. Therefore, this study aimed to achieve a uniform distribut...

The removal of biopolymer natural organic matter surrogates (uncharged dextran and anionic alginate, both polysaccharides) spiked in ultra-pure (UP) and tap water was investigated with weak (WBA) and strong (SBA) basic anion exchange resins (AER). It was found that SBA resins with OFT counter ions could remove up to 95% of the dextran by Hbonding i...

In the present study, the impact of hydrocarbons on soil health was examined and the effectiveness of the bioventing method to mitigate damage was evaluated. The three soils analyzed presented a clayey-sandy and clayey texture, and although the contamination did not significantly affect their water retention capacity, there was a loss of nutrients....

Sodium, potassium, and protons are the most important ions for life on earth, and their homeostasis is crucially needed for the survival of cells. The biological cells have developed a system that regulates and maintains the integrity of the cells by facilitating the exchange of these ions. These systems include the specific type of ion transporter...

Sequestration of CO2 within stable mineral carbonates (e.g., CaCO3) represents an attractive emission reduction strategy as it offers a leakage-free alternative to geological storage of CO2 in an environmentally benign form. However, the pH of aqueous streams equilibrated with gaseous streams containing CO2 (pH 8). Traditionally, alkalinity is pro...
