Summary: Water sources with high uranium prevalence pose potential health risks. The development of efficient uranium scavenging water treatment techniques is of great importance. NH2-MCM-41(MCM-a) was synthesized and grafted using salicylaldehyde (MCM-s) and 3-hydroxybenzoic acid (MCM-hb). The results showed that MCM-s had the highest adsorption capacity under the optimum conditions. The thermodynamic parameters indicated the feasibility of the adsorption process. MCMs exhibit rapid adsorption rate, high adsorption efficiency, and regeneration ability, making them promising for uranium removal in water treatment.

Summary: Biosorption using phosphorylated hazelnut shell waste (FHS) is a promising method for lithium removal and recovery. This study investigated the performance of a continuous-flow packed-bed column system using FHS for ultra-low level lithium removal. The results showed that the lihium biosorption capacity of the FHS column was unaffected by the bed height, but decreased with increasing flow rate.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.

Summary: Analysis of in vivo exposure to traditional Chinese medicine using mass spectrometry is helpful for identifying effective ingredients and developing new drugs. This study focused on Forsythia suspensa (Lian Qiao) and used metabolomics technology to explore its in vivo exposure. By comparing the differences before and after administration, a complete set of nontargeted analysis strategies for TCM exposure was established. The study identified 393 Lian Qiao-related chemical components in mice after administration, including prototypes and metabolites. This study provides a reference for research on the active ingredients of Lian Qiao in vivo.
