With the diversion rate of ginkgolide A, B, K as comprehensive evaluation indexes, the amount of activated carbon, ad- sorption time, mix rate, and adsorption temperature were selected as factors, orthogonal design which based on the evaluation method of information entropy was used to optimize activated carbon adsorption technology of ginkgo diterpene lactones meglumine injection. Opti- mized adsorption conditions were as follows: adsorbed 30 min with 0.2% activated carbon in 25 °C, 40 r ·min⁻¹, validation test re- sult display. The optimum extraction condition was stable and feasible, it will provide a basis for ginkgo diterpene lactone meglumine injection' activated carbon adsorption process.

The structure and active components of the filling material play a critical role in the contamination remediation performance of permeable reactive barriers. However, current methods lack a comprehensive understanding of the structural evolution and long-term performance of these materials during remediation processes. This study utilizes column experiments combined with spectral induced polarization (SIP) monitoring to investigate the effectiveness of zero-valent iron (ZVI), activated carbon (AC), and their composite with sand in removing Cr(VI).

A novel nanocomposite magnetic hydrogel was synthesized based on κ-carrageenan, acrylic acid, and activated carbon as an absorbent for removing heavy metal ions from aqueous solution. FT-IR spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and vibration sample magnetometer (VSM) were employed to confirm the structure of the nanocomposite hydrogels. The effects of contact time, pH, particle size, temperature, and metal ion concentration on the metal ion adsorption were investigated.

The Campylobacter prevalence in free-ranging broiler flocks is usually higher than in conventional flocks, and effective interventions for this production type are needed. This study aimed to investigate the on-farm Campylobacter-reducing effect of feeding three feed additives or a water additive to broilers from hatching to slaughter. Newly hatched Ranger Gold broilers (n = 140) were randomly placed into five cages (n = 28/cage) within a flock of 6,000 broilers.

Phytophthora blight caused by Phytophthora capsici is a serious disease affecting a wide range of plants. Biochar as a soil amendment could partially replace peat moss and has the potential to suppress plant diseases, but its effects on controlling phytophthora blight of container-grown peppers have less been explored, especially in combination of biological control using Trichoderma. In vitro (petri dish) and in vivo (greenhouse) studies were conducted to test sugarcane bagasse biochar (SBB) and mixed hardwood biochar (HB) controlling effects on pepper phytophthora blight disease with and without Trichoderma.
