چکیده

در پژوهش حاضر، غشاهای نانوکامپوزیتی از نانوذرات آب‌دوست روی اکسید (ZnO) و پلی وینیلیدن فلوراید (PVDF) توسط روش تغییر فاز تهیه شدند. اثر غلظت‌های مختلف نانوذرات در ساخت غشاها بر عملکرد جداسازی محلول‌های مختلف مورد ارزیابی قرار گرفت. جهت ارزیابی ساختار و شیمی سطح غشاها از تصاویر میکروسکوپی الکترونی روبشی و طیف سنجی مادون قرمز تبدیل فوریه (ATR-FTIR) استفاده شده است. نتایج نشان می‌دهد که محتوای آب غشاهای ساخته شده از 96/77% در غشای M1 بدون نانوذره به 60/79% در غشای M3 شامل 1/0% وزنی از نانوذرات افزایش می‌یابد و سپس به 59/66% در غشای M5 کاهش پیدا می‌کند. بالاترین میزان شار آب خالص عبوری L/m2h 97/19 در 1/0% وزنی نانوذرات (غشای M3) به‌دست آمد. لازم به ذکر است که فاکتور پس‌دهی سدیم سولفات در غشاها دارای روند افزایشی- کاهشی است و از 59% به 82% در غشای M3 افزایش و سپس از 82 به 62% کاهش می‌یابد. بنابراین، نتایج عملکرد بهینه را برای غشای M3 نشان می‌دهند. این مطالعه پتانسیل غشاهای تهیه شده از پلی وینیلیدین فلوراید/ روی اکسید را برای کاربردهای تصفیه فاضلاب نشان می‌دهد.

چکیده [English]

In this research, polyether sulfone (PES)/ polyvinylidene fluoride (PVDF) nanocomposite membranes were prepared form hydrophilic ZnO nanoparticles by phase inversion process. The effects of different concentrations of nanoparticles were investigated in terms of separation performance. In addition, the prepared membranes were characterized by SEM and AT-IR analysis. The results showed that the water content membranes increase from 77.96% in M1 (without nanoparticle) to 79.60% in M3 for 0.1 wt.% of ZnO, and the highest pure water flux was observed 19.97 L/m2h in 0.1 wt.%. Furthermore, the Na2SO4 rejection increased from 59% in M0 to 832% in M3. Thus, M3 showed the best performance separation among all prepared membranes. Ultimately, this study shows the potential PVDF-PES/ZnO membranes for application in wastewater treatment.
