Cellulose acetate (CA) and activated carbon (AC) were used as base material and additive, respectively, to prepare CA/AC composite membranes. By adjusting the AC content (5%, 10%, 15%, and 20%), the morphology and the adsorption capability of the samples for target dyes were studied. The results showed that the surface flatness and compactness of the barrier layer deteriorated with increasing AC content. In addition, the pore size and structures of the supporting layer became large due to the partial agglomeration of the AC in the CA. The relationship between adsorption time and adsorption capability was investigated. It was found that the 15% AC composite membrane possessed the highest adsorption efficiency for acid blue dye. The adsorption equilibrium was 58.69 mg/g for 60 mg/L acid blue dye at 120 min. For acid yellow and acid dark dye, the adsorption equilibria were 58.23 and 58.34 mg/g, respectively.

醋酸纤维素（CA）和活性炭（AC）分别用作基础材料和添加剂，以制备CA / AC复合膜。通过调节AC含量（5％，10％，15％和20％），研究了样品对目标染料的形态和吸附能力。结果表明，随着AC含量的增加，阻挡层的表面平整度和致密性降低。另外，由于CA中AC的部分聚集，支撑层的孔径和结构变大。研究了吸附时间与吸附能力之间的关系。发现15％AC复合膜对酸性蓝染料具有最高的吸附效率。60 mg / L酸性蓝染料在120分钟时的吸附平衡为58.69 mg / g。对于酸性黄和酸性深色染料，
