Abstract    The objective of this work is to develop a new class of nanocomposite ultrafiltration (UF) membranes with excellent solute rejection rate and superior water flux using zeolitic imidazolate framework-8 (ZIF-8) and multi-walled carbon nanotubes (MWCNTs). The effect of ZIF-8 and MWCNTs loadings on the properties of polyvinyldifluoride (PVDF)-based membrane were investigated by introducing respective nanomaterial into the polymer dope solution. Prior to filtration tests, all the membranes were characterized using several important analytical instruments, i.e., SEM-EDX and contact angle analyzer. The addition of the nanoparticles into the membrane matrix has found to increase the membrane pore size and improve its hydrophilicity compared to the pristine membrane. The separation performance of membranes was determined with respect to pure water flux and rejections against bovine serum albumin (BSA) and humic acid (HA).The experimental findings indicated that the nanocomposite membranes in general demonstrated higher permeation flux and solute rejection compared to the pristine membrane and the use of ZIF-8 was reported to be better than that of MWCNTs in preparing nanocomposite UF membranes owing to its better flux and high percentage of solute rejection.

چکیده    چكيدههدف از این کار توسعه یک کلاس جدید از غشاهای فوق فرآیند نانوکامپوزیتی (UF) با میزان ردگیری عالی و شار برتری آب با استفاده از زئولیت ایزادولات چارچوب 8 (ZIF-8) و چند نانولوله های کربنی چندتایی (MWCNTs) است. تأثیر بارگذاری های ZIF-8 و MWCNT ها بر خصوصیات پلیمویل دی فلوئورید (PVDF) غشای پایه با معرفی نانومواد مربوطه به محلول پلیمری پلیمر مورد بررسی قرار گرفت. قبل از آزمایش های تصفیه، تمام غشاها با استفاده از چندین ابزار تحلیلی مهم، یعنی SEM-EDX و آنالیز زاویه تماس، مشخص شدند. افزودن نانو ذرات به ماتریس غشایی، افزایش اندازه نمک غشاء را افزایش داده و هیدروفیل بودن آن را نسبت به غشاء بتونه بهبود می بخشد. عملکرد جداسازی غشا با توجه به شار خالص آب و رد شدن بر آلبومین سرم گاو (BSA) و اسید هومیک (HA) تعیین شد. یافته های آزمایش نشان داد که غشاهای نانوکامپوزیتی به طور کلی شوری نفوذی و رد پراکندگی را نسبت به بوته غشاء و استفاده از ZIF-8 بهتر از MWCNT ها در تهیه غشاء نانوکامپوزیت UF به دلیل شار مطلوب و درصد بالا رد حلال
