Powder activated carbon (PAC), derived from calligonum pollygonides, was successfully modified with the ionic liquid (IL) trihexyltetradecylphosphonium bromide ([PC₆C₆C₆C₁₄][Br]) in the presence of sodium alginate and characterized using SEM, FTIR and TGA. PAC, granular AC (GAC), AC-alginate and AC-Alg-IL bead were assessed for the removal of phenol from aqueous media via batch adsorption. Both PAC and AC-Alg-IL beads displayed high adsorption capacities, 123 mg/g and 78 mg/g, respectively, under optimized conditions. In contrast, GAC gave a much lower adsorption capacity than AC-ALG-IL beads, indicating that AC-ALG-IL beads are superior as potential adsorbents for this industrial application. Theoretical studies showed that the pseudo-second-order kinetic and Freundlich isotherm models were suitable to describe the adsorption process. The interaction between phenol and AC-Alg-IL beads was analyzed using the conductor-like screening model for realistic solvents (COSMO-RS). It has been concluded that AC-Alg-IL beads can be used as an efficient adsorbent for phenol and other organic compounds.

粉状活性炭 (PAC) 来源于 calligonum pollygonides，成功地用离子液体 (IL) 三己基_十四烷基溴化鏻 ([PC ₆ C ₆ C ₆ C ₁₄][Br]) 在海藻酸钠存在下并使用 SEM、FTIR 和 TGA 进行表征。对 PAC、颗粒活性炭 (GAC)、活性炭-藻酸盐和 AC-Alg-IL 珠粒通过批量吸附从水性介质中去除苯酚进行了评估。在优化条件下，PAC 和 AC-Alg-IL 珠粒均显示出高吸附容量，分别为 123 mg/g 和 78 mg/g。相比之下，GAC 的吸附能力比 AC-ALG-IL 珠低得多，这表明 AC-ALG-IL 珠作为该工业应用的潜在吸附剂是优越的。理论研究表明，拟二级动力学模型和 Freundlich 等温线模型适用于描述吸附过程。苯酚和 AC-Alg-IL 珠粒之间的相互作用使用类似导体的真实溶剂筛选模型 (COSMO-RS) 进行分析。
