Cerium fluoride (CeF₃) nanoparticles (NPs) were synthesized and applied in polysulfone (PS) membrane fabricated by phase inversion method. The produced nanocomposite membranes (PS/CeF₃) with different contents of CeF3 NPS (0.25%, 0.5%, 0.75% and 1% w/w) were used to treat pharmaceutical wastewaters. The membranes were characterized by FESEM, EDX, XRD, FTIR, porosity, and water contact angle analyses. Evaluation of the characteristics and performance of the nanocomposite membranes confirmed that utilizing photocatalytic CeF₃ NPs in membrane structure could effectively decompose organic contaminants in pharmaceutical wastewaters. It also improves the hydrophilicity and antifouling ability of membrane during filtration especially, in the presence of UV irradiation. The permeate flux of the PS membrane increased from 35.1 to 63.77 l/m²h by embedding 0.75% of CeF₃ NPs in membrane structure due to the porosity enhancement from 71.36–78.42% and the decrease in contact angle from 62.9º to 53.73º. Moreover, the flux decline of PS/CeF₃-0.75% membrane under UV irradiation was from 63.6 to 46.1 l/m²h that considerably lower than that of the neat PS membrane (from 34.7 to 4.9). On the other hand, the degradation efficiency of PS/CeF₃-0.75% membrane was more than 97%, and COD removed was more than 65% while they were 75% and 31%, respectively for the nascent PS membrane. Therefore, applying the appropriate amount of CeF₃ NPs in PS membranes not only greatly increased the permeate flux but also significantly enhanced the degradation efficiency and COD removal. This indicates that nanocomposite membranes can be confidently applied for pharmaceutical wastewater treatment UV irradiation.

合成了氟化铈 (CeF ₃ ) 纳米粒子 (NPs) 并将其应用于通过相转化法制备的聚砜 (PS) 膜中。制备的具有不同CeF3 NPS 含量（0.25%、0.5%、0.75% 和1% w/w）的纳米复合膜（PS/CeF ₃）用于处理制药废水。通过FESEM、EDX、XRD、FTIR、孔隙率和水接触角分析对膜进行表征。对纳米复合膜的特性和性能的评估证实，利用光催化 CeF ₃膜结构中的纳米颗粒可以有效分解制药废水中的有机污染物。它还提高了过滤过程中膜的亲水性和防污能力，尤其是在紫外线照射下。通过在膜结构中嵌入 0.75% 的 CeF ₃ NP，PS 膜的渗透通量从 35.1 增加到 63.77 l/m ² h，这是由于孔隙率从 71.36–78.42% 增加，接触角从 62.9º 减小到 53.73º . 此外，PS/CeF ₃ -0.75% 膜在紫外线照射下的通量下降从 63.6 到 46.1 l/m ² h，远低于纯 PS 膜（从 34.7 到 4.9）。另一方面，PS/CeF ₃的降解效率-0.75% 的膜为 97% 以上，COD 去除率超过 65%，而新生 PS 膜的 COD 去除率分别为 75% 和 31%。因此，在PS膜中应用适量的CeF ₃ NPs不仅大大提高了渗透通量，而且显着提高了降解效率和COD去除率。这表明纳米复合膜可以自信地应用于制药废水处理紫外线照射。
