Summary: This study investigates the stability of Cs+-exchanged zeolite 13X using thermal treatment. The results show that extraframework Cs+ can stabilize the zeolite framework, but with increasing treatment temperature, Cs+ migrates from spacious sites to confined sites, resulting in lower leaching. During high-temperature treatment above 900℃, the zeolite framework is completely destroyed and nonporous phases are formed, with Cs+ mainly existing in amorphous phases and pollucite. Therefore, thermal treatment to form pollucite is recommended for storing Cs+-exchanged zeolite 13X in nuclear waste repositories to achieve maximum Cs+ retention.

Summary: In recent years, porous adsorption materials have received extensive attention in environmental remediation. However, green preparation and effective post-treatment are still the main challenges in practical applications. In this study, a novel porous adsorbent was successfully fabricated from aqueous foams templates stabilized by natural plant Sapindus mukorossi (S. mukorossi) and nano-clay attapulgite (APT) via a thermally-initiated polymerization. The as-prepared porous adsorbent exhibited abundant interconnected pore structures and demonstrated excellent adsorption properties for chlortetracycline hydrochloride (CTC) and tetracycline hydrochloride (TC), with a maximum adsorption capacity of 620 mg/g and 538 mg/g, respectively. After adsorption, the waste porous adsorbent was converted into carbon/APT material through anaerobic calcination. At a carbonization temperature of 400 degrees C, carbon/APT with large amounts of negative charges and oxygen-containing functional groups exhibited a good adsorption capacity for Cd2+ and showed potential as a soil remediation agent.

Summary: Super-wetting membranes with catalytic performance were fabricated using Fe3O4-loaded attapulgite (FATP) nanofibers. These membranes possess hydrophilicity and micro-nano roughness, which resist oil fouling and act as a catalyst for the Fenton-like reaction. During oil-in-water filtration, more than 99.5% of oil droplets can be rejected, and membrane permeance remains at 62% of its initial value. After hydraulic cleaning, the permeance recovers to 85%, and the remaining 10.9% can be restored through the Fenton-like reaction. This study provides insights into the catalytic mechanism of membranes after oil fouling.

Summary: In this study, functional Zn-based mixed metal oxides (Zn-MMOs) were fabricated using a ZnO-assisted hydrothermal coprecipitation method with spent metal ions from acid-leached clay for antibiotic and microorganism removal from water. The results demonstrated that the composition, micro-structure, adsorption, and antibacterial activity of Zn-MMOs were influenced by the amount of ZnO added. Zn-MMOs showed high adsorption capabilities for tetracycline and chlortetracycline, as well as comparable antibacterial activity to commercial ZnO, making them effective for eliminating microbial contaminants in water. This work offers a collaborative solution for waste resource utilization and wastewater pollution treatment, contributing to the promotion of green economy and sustainable development.
