Summary: The hydrolysis reactions of anhydride are commonly used as model reactions for thermal hazard study. These reactions are initially heterogeneous liquid-liquid systems, but become homogeneous as the hydrolysis product increases the solubility of anhydride in water. This autocatalytic behavior poses a challenge for modeling the anhydride hydrolysis reactions. In this study, the hydrolysis of propionic anhydride was investigated and a reaction model considering both reaction kinetics and anhydride solubility was developed.

Summary: This study introduces a new method for preparing lotus seed starch nanocrystals (LS-SNCs) using acid hydrolysis combined with ultrasonic-assisted acid hydrolysis (U-LS-SNCs). The structural characteristics of the starch nanocrystals were evaluated through various analyses. The results showed that U-LS-SNCs can be prepared in a shorter time with smaller particle size and molecular weight compared to LS-SNCs. The modified nanocrystals showed high relative crystallinity and can be widely used in various applications.

Summary: The study found that the ultrasonic-assisted one-stage leaching process can efficiently leach lead from zinc leaching residue, with better results than the conventional process. The ultrasonic-assisted leaching process is controlled by a diffusion model and can release lead by forming PbCl42-, avoiding the precipitation of PbCl2. In addition, introducing ultrasound can lower the leaching temperature and reduce the amount of leaching agent.

Summary: Worldwide rapid urbanization and development have led to the release and dispersion of anthropogenic heavy metals, posing serious threats to aquatic ecosystems and human health. Although various methods for removing heavy metal ions from aqueous solutions have been explored, there is still a need for improvement in the efficient and pertinent treatment of heavy metal pollution. Adsorption is considered the best technique for heavy metal removal, and metal-organic frameworks (MOFs) are recognized as one of the most promising emerging adsorbents with excellent adsorption properties. This review provides a comprehensive overview of MOFs synthesis techniques, functionalization methods, and adsorption mechanisms, as well as a detailed comparison of their applications in heavy metal removal, aiming to offer a strong reference for MOFs synthesis and a feasible solution for heavy metal treatment.

Summary: Ti-MOF-SH was successfully synthesized by a simple one-step method. The kinetics, capacities, selectivities, repeatabilities and mechanisms of Hg2+ and Pb2+ absorption and removal by Ti-MOF-SH were investigated. It was found that Ti-MOF-SH had a maximum adsorption capacity of 943 mg/g for Hg2+ and 341 mg/g for Pb2+ under the optimum pH (5.0) at 298 K. The adsorption process was endothermic, conforming to the pseudo-second-order kinetic model and Langmuir model, and mainly relied on electrostatic interaction and chelation of functional groups. Ti-MOF-SH exhibited excellent selectivity and repeatability for Hg2+ and Pb2+ and is expected to have wide applications in the future.

Summary: Considering resource reserve and environmental protection, recovering palladium from spent catalysts is of great significance. This study proposes an external field enhancement method with ultrasonic-assisted ozone for palladium recycling. Ultrasonic mechanical and cavitation effects can destroy cladding layer and promote solid-liquid interface reaction, while ultrasonic excitation of ozone can generate highly oxidizing free radicals to improve oxidation and accelerate the oxidation rate of palladium.
