Summary: In this study, xanthan gum-based composites were successfully graft-modified by amantadine (XG-Fe3+/AM) to enhance the adsorption capacity and selectivity for methylene blue (MB) from aqueous solutions. The adsorption equilibrium of MB was achieved within 5 minutes at an initial concentration of 100 mg/L, with a maximum adsorption capacity of 565 mg/g. XG-Fe3+/AM showed a high removal rate of 95% for MB even after 5 desorption-regeneration cycles. The adsorption performance of MB was systematically examined by pH, contact time, temperature, and initial dye concentration.

Summary: In this study, a MMT/XG-Alg hybrid hydrogel nanocomposite was synthesized for the adsorption of MG. The structure and morphology of the hybrid nanocomposites were identified using BET, FTIR and SEM analyses. The optimal adsorption conditions were determined to be pH = 6, temperature 318 K, contact time 240 min, and the maximum adsorption capacity was found to be 769.23 mg/g. The adsorption process followed the Langmuir isotherm model, with MMT(0.5CMC)/XG-Alg showing the highest adsorption capacity. Kinetics were described by the pseudo-second order model, and thermodynamic parameters indicated an endothermic and spontaneous sorption process.

Summary: This study focused on the recovery of rare earth elements (REEs) from kaolinite through selective leaching and the synthesis of zeolites from the leaching residue. The results showed that the pH static leaching method achieved over 90% leaching of REEs from metakaolinite, while only extracting less than 2% of the major constituents. Zeolites with different compositions were successfully synthesized, and high purity sodalite exhibited superior adsorption capacity for Ce3+ compared to zeolite A. These findings suggest that kaolinite could be a potential source for REE recovery, and the resulting leaching residue could be used for the synthesis of zeolites as promising adsorbents for Ce3+ recovery.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
