Summary: Soils are complex mixtures with unique properties that affect the sorption process of contaminants. This study investigated the sorption of ivermectin in two soil types and found that factors such as soil type, solution pH, ivermectin concentration, and temperature influenced the sorption process. The results also showed that the sorption of ivermectin occurred mainly on the soil surfaces and within the soil pores or phases.

Summary: This study investigated the adsorption and desorption of gallic acid (GA), protocatechuic acid (PCA), chlorogenic acid (CGA), and 4-hydroxybenzoic acid (4-HBA) using commercially available mesoporous silica materials (MSMs). The results showed that amine-modified SBA-15 mesoporous silica exhibited the highest adsorption capacity for GA, and the antioxidant capacity of the adsorbed compounds was preserved after desorption.

Summary: This study evaluated the adsorption of volatile organic compounds (VOCs) on three different adsorbents and found that the adsorption capacity was influenced by pore size, surface area, and polarity. Palygorskite showed the highest adsorption capacity due to its small total pore volume and large micropore volume. The study also constructed pore models and analyzed the adsorption heat, concentration distribution, and interaction energy, revealing that smaller pores result in higher VOC concentration.

Summary: This study improved the surface quality of synthetic hematite iron oxide coated sand and evaluated its adsorption and desorption capabilities for copper ions. It was found that the coating at a lower pH resulted in higher copper ion removal efficiency, reaching 94%. Acidic solutions were identified as effective desorption media for copper ions on the surface of hematite iron oxide coated sand.

Summary: Plastic debris, especially microplastics (MPs), can bind with pollutants and be ingested by humans, increasing the health risks. This study investigated the adsorption and desorption behavior of polycyclic aromatic hydrocarbons (PAHs) on different types of MPs, and assessed the potential carcinogenic risk. The results showed that higher molecular weight PAHs were more easily adsorbed on MPs, with polyethylene (PE) having higher adsorption efficiency than polymethyl methacrylate (PMMA). The desorption experiments in a simulated digestive system revealed that the activity of digestive enzymes affected the desorption, with PMMA showing higher desorption efficiency than PE. Molecular dynamics simulation confirmed enzyme-induced desorption. Risk assessment indicated that PAHs desorption from PMMA posed a higher carcinogenic risk compared to PE. This study enhances understanding of the interactions between pollutants, MPs, and human health risks.

Summary: In this study, a mesoporous poly(N,N-0-methylene-bis(1-(3-vinylimidazolium)) chloride), labeled as PDVIm-Cl, with double anions (Cl-) and low monomer molecular weight was synthesized and utilized for the adsorption of anionic dyes. The PIL exhibited superior adsorption ability towards anionic dyes, with RB19 achieving the highest capacity. The material showed high removal efficiencies for anionic dyes over a wide pH range and demonstrated great reusability in continuous column adsorption-desorption processes.

Summary: In this study, a dual-pH-sensitive chitosan/mesoporous silica nanoparticle-based anticancer drug delivery system was developed using the tumor-triggered targeting strategy. Both in vitro and in vivo studies demonstrated that the system could induce cancer cell apoptosis, inhibit tumor growth, and reduce the cytotoxicity of the drug against normal cells, showing potential for cancer therapy.

Summary: Orally administered tetracycline antibiotics may be affected by their interaction with feed, leading to changes in their bioavailability and efficacy. This study investigated the pH-dependent adsorption of doxycycline in animal feed and its release pattern in simulated gastrointestinal conditions. The results showed strong interactions between doxycycline and the organic biomass in the feed. The release of doxycycline was found to occur in three stages, with the highest release efficiency suggesting good bioavailability in ruminants after oral administration.
