Objective: To study the technological parameters of the purification process of Depsides in Salvia miltiorrhiza with macroporous resin.
Method: The adsorptive characteristics and eluting parameters of the process were studied by taking the content of depsides as index.
Result: 85 mL of extractive of depsides (1.25 g x mL(-1)) was purified with a column of macroreticular resin ( Phi30 mm,127 mL) and washed with 4 BV of distilled water, the eluted with 4 BV of 80% ethanol (1% ammonia).
Conclusion: This process of applying macroporous resin to adsorb and purify depsides in S. miltiorrhiza is feasible.

The purification efficiency of autoexhaust carbon strongly depends on the heterogeneous interface structure between active metal and oxide, which can modulate the local electronic structure of defect sites to promote the activation of reactant molecules. Herein, the high-dispersion CuO clusters supported on the well-defined CeO nanorods were prepared using the complex deposition slow method. The formation of heteroatomic Cu-O-Ce interfacial structural units as active sites can capture electrons to achieve activation of the NO and O molecules.

This research explores the biosorption of Rhodamine B (Rd-B) and Sunset Yellow (SY) dyes using cross-linked chitosan-alginate (Ch-A) biocomposite beads, combining experimental investigations with theoretical studies to elucidate the biosorption mechanisms. The biocomposite beads were synthesized through an eco-friendly cross-linking method, and their structural properties were characterized using various characterization techniques. Complementary theoretical studies using Monte Carlo (MC) simulations and molecular dynamics (MD) calculations provided insights into the molecular interactions between the dyes and the biocomposite beads.

Hexagonal boron nitride (h-BN) exhibits unique application potential in water purification due to its large specific surface area, high porosity, and chemical inertness. Designing adsorbents with highly active adsorption sites is one effective method to improve their adsorption capacities. In this study, porous h-BN aerogels containing multiple defect types (DP-BN) were synthesized by using salt templates.

OH-mediated advanced oxidation processes (AOPs) are widely used in wastewater treatment and drinking water purification. Recently, an increasing number of studies have indicated that common inorganic nitrogen ions can efficiently generate •OH under UV irradiation, demonstrating strong performance in the degradation of various contaminants. Conversely, the presence of inorganic nitrogen ions in UV or other oxidation processes dramatically increases the yield of toxic nitro (so)-aromatic products and the formation potential of nitrogenous disinfection by-products with high genotoxicity and cytotoxicity.

Adeno-associated viruses (AAV) are among the leading vectors for in vivo gene therapy. The purification of AAV remains a bottleneck as it typically requires multiple individual process steps, often resulting in product loss and high costs. Current downstream processes are usually serotype-specific and rely primarily on expensive affinity resins.
