Summary: The use of pottery granules (PG) as an adsorbent for removing toxic metal Pb(II) from drinking water was studied. The physicochemical factors such as contact time, PG dose, pH, solution temperature, and coexisting ions were investigated. The results showed that PG had efficient adsorption capacity for Pb(II), with removal increasing with increasing PG dose and agitation time, and decreasing with increasing Pb(II) concentration. The adsorption process was described as favorable, with Pb(II) being adsorbed in multilayers onto the PG surface.

Summary: The main sources of heavy metal pollution are industrial wastewater and waste residues, which have serious detrimental effects on water and soil environments as well as human health. In this study, a gel adsorbent (AA-SW-AMPS) was prepared using microwave-assisted chemical cross-linking with fir sawdust as the raw material, following the principle of waste utilization. The microstructure, reaction mechanism, and water absorption performance of AA-SW-AMPS were investigated using SEM, FTIR, XRD, and swelling dynamic experiments. The results showed that AA-SW-AMPS had a porous structure with a specific surface area of 240.75 cm²/g, enabling excellent sorption of heavy metals.

Summary: The heavy metal ions present in industrial wastewater pose a significant threat to human health. To mitigate heavy metal ion pollution, it is crucial to explore an adsorbent that is low-cost, environmentally friendly, exhibits high adsorption capacity, and is easily recyclable. In this study, lignin sulfonate derived from corn stover was modified using a hydrothermal method, resulting in a porous structure that provides more internal adsorption sites for heavy metal ions. The modified lignosulfonate adsorbent efficiently removes heavy metals, particularly Cu2+ and Pb2+, from wastewater, with an adsorption capacity of 450.3 mg/g for Cu2+ and 475.4 mg/g for Pb2+. Additionally, at a concentration of 40 mg/L for Cu2+ and Pb2+, and using a dosage of 0.4 g/L of adsorbent, the adsorption equilibrium is achieved within 60 minutes. Furthermore, the adsorbent achieves removal rates of 83% for Pb, 72% for Cd, 87% for Cu, 36% for Zn, 25% for Mn, 95% for Cr, and 99% for Fe in wastewater within 2 hours. This research demonstrates the development of a practical adsorbent for the removal of heavy metals from real-world wastewater.

Summary: Water is crucial for human survival, particularly in arid regions or places with limited fresh water. Desalination is an effective method for meeting the increasing water demand. Membrane distillation technology, which operates at low temperature and pressure, is used for water treatment and desalination. However, the challenges of water efficacy and biofouling arise due to the lack of suitable and versatile membranes. Researchers have explored different membrane composites to develop efficient and biofouling-resistant membranes for membrane distillation.

Summary: A simulation model was used to evaluate the effect of capillary pressure on CO2 capture by membrane absorption. The study found that the use of a hydrophilic membrane resulted in higher CO2 flux. Additionally, the effect of capillary pressure increased as the membrane pores became smaller, leading to an increase in CO2 flux. The replacement of water absorbent with a 1 M monoethanolamine solution also significantly increased CO2 flux.
