Industrial wastewater often contains xenobiotics such as heavy metals, dyes and proteins, yet there is a lack of efficient cleaning methods. Therefore, here we fabricated hollow fiber membranes using polyphenylsulfone containing 1, 3 and 5 wt% of cellulose acetate and cellulose acetate phthalate by non-solvent induced phase separation. Membrane morphology was characterized by field emission scanning electron microscopy. The hydrophilicity of the membranes was measured by contact angle, water uptake and porosity measurement. The thermal miscibility of the membrane with additives was assessed by thermogravimetric analysis. Hollow fiber membranes were tested for separation of azo dyes, e.g., reactive orange 16 and reactive black 5, and of proteins: bovine serum albumin, egg albumin and pepsin. Results show increasing rejection of dyes and proteins with the content of cellulose acetate and cellulose acetate phthalate. Water permeability was 41.26 L/m² h bar for the polyphenylsulfone membrane, 64.47 L/m² h bar for the polyphenylsulfone/5 wt% cellulose acetate membrane and 72.60 L/m² h bar for the polyphenylsulfone/5 wt% cellulose acetate phthalate membrane.

工业废水通常包含异种生物，例如重金属，染料和蛋白质，但缺乏有效的清洁方法。因此，在这里，我们通过非溶剂诱导的相分离，使用含有1、3和5重量％的乙酸纤维素和邻苯二甲酸乙酸纤维素的聚苯砜制备了中空纤维膜。通过场发射扫描电子显微镜表征膜的形态。通过接触角，吸水率和孔隙率测量来测量膜的亲水性。膜与添加剂的热混溶性通过热重分析进行评估。测试中空纤维膜以分离偶氮染料，例如活性橙16和活性黑5，以及分离蛋白质：牛血清白蛋白，蛋清蛋白和胃蛋白酶。结果表明，随着醋酸纤维素和邻苯二甲酸醋酸纤维素含量的增加，染料和蛋白质的排阻增加。透水率为41.26 L / m聚苯砜膜为² h bar，聚苯砜/ 5 wt％乙酸纤维素膜为64.47 L / m ² h巴，聚苯砜/ 5 wt％乙酸邻苯二甲酸纤维素膜为72.60 L / m ² h bar。
