Activated carbon (AC)-containing porous cellulose beads (ACPBs) with a three-dimensionally interconnected porous structure and high impact strength were prepared in a single step from cellulose acetate and AC via a non-solvent-induced phase separation process at room temperature. The adsorption behavior of the ACPBs was evaluated using toluidine blue (TB) dye as a model adsorbate. The effects of initial dye concentration and contact time on the adsorption kinetics and isotherms of ACPBs were studied. The adsorption of TB by the ACPBs followed pseudo-second-order kinetics and could be expressed by the Langmuir adsorption isotherm model. ACPB adsorbed 119.1 mg/g of TB at an initial TB concentration of 101.0 mg/L and the Langmuir equation predicted that the maximum adsorption capacity of ACPBs for TB was 123.5 mg/g. ACPBs could retain original shape and around 85% of their adsorption capacity after three times recycle. Furthermore, ACPBs efficiently removed malodorous gases from gas mixtures, indicating potential for environmental applications including toxic dye and gas elimination.

在室温下，通过非溶剂诱导的相分离过程，由乙酸纤维素和AC一步制得具有三维互连多孔结构和高冲击强度的含活性炭（AC）的多孔纤维素珠（ACPB）。使用甲苯胺蓝（TB）染料作为模型吸附物评估ACPB的吸附行为。研究了初始染料浓度和接触时间对ACPBs吸附动力学和等温线的影响。ACPB对TB的吸附遵循伪二级动力学，可以用Langmuir吸附等温线模型表示。ACPB在101.0 mg / L的初始TB浓度下吸附了119.1 mg / g的TB，Langmuir方程预测ACPBs对TB的最大吸附容量为123.5 mg / g。回收三遍后，ACPB可以保留原始形状，并保持其吸附能力的85％左右。此外，ACPB有效地去除了混合气体中的恶臭气体，表明其在环境中的应用潜力很大，包括有毒染料和气体消除。
