چکیده

در این پژوهش، غشاهای نانوفیلترسیون پلیمری بر پایه پلیمر پلی اتر سولفون تهیه شده به‌روش غوطه‌وری در حمام غیرحلال، با استفاده از ترکیب پلیمر کیتوسان و نانو صفحه‌های گرافن اکساید، اصلاح سطحی شدند و اثر این لایه‌نشانی بر خواص عملکردی و ضد گرفتگی غشا مورد بررسی و ارزیابی قرار گرفت. غشاهای اصلاح سطح شده به‌طور قابل توجهی جداسازی نمک را بهبود دادند و خاصیت آبدوستی در آن‌ها بیشتر از غشای پلیمری پلی اتر سولفون پیش از فرآیند اصلاح بود. مقدار جداسازی نمک از 68% به مقدار 94% افزایش یافت که دلیل آن، کاهش اندازه و اندازه حفرات موجود در سطح بود. خاصیت جذب در پلیمر کیتوسان و نانو صفحه‌های گرافن اکساید در تماس با محلول خوراک به‌عنوان دلیل دیگری در این زمینه گزارش گردید. این در حالی بود که مقدار شار آب عبوری از غشا در اثر لایه‌نشانی لایه پلیمری و افزایش ضخامت لایه جداساز کاهش یافت. زاویه تماس آب نیز در اثر بهبود آبدوستی و وابستگی سطح در نتیجه لایه نشانی لایه آبدوست کیتوسان و نانو صفحه‌های گرافن اکساید، کاهش یافت که این به معنی افزایش آبدوستی در غشاهای فوق بود. مورفولوژی سطح غشاهای اصلاح شده از حالت زبر با میانگین nm 11 در غشای پلی اتر سولفون به حالت صاف‌تر در غشاهای اصلاح شده با میانگین nm 5 تغییر یافت. نرخ بازیابی شار و نرخ گرفتگی کلی در توافق کامل با نتایج حاصل از زاویه تماس آب و میزان پارامتر زبری سطح محاسبه شده به‌دست آمد. افزایش نرخ بازیابی شار و کاهش نرخ گرفتگی بیانگر بهبود موفقیت‌آمیز خواص ضدگرفتگی در نتیجه فرآیند لایه‌نشانی بود.

چکیده [English]

In the current study, prepared PES nanofiltration membranes with phase inversion method were modified by the novel composite chitosan/GO (graphene oxide) nano-sheets coating process and the effect of coating on performance and membrane antifouling properties was investigated. The results revealed that the salt rejection strongly improved, and their hydrophilicity enhanced rather than PES. The rejection increased from 68% for PES to 94% due to pore size reduction and improvement in adsorption. But permeability flux was decreased by increasing skin layer after coating. In addition, contact angle was decreased because of chitosan and GO nano-sheets hydrophilic nature. The surface morphology was changed from rough surface to smoother one by coating. Finally, flux recovery ratio and total fouling ratio were in good agreement with contact angle results and roughness parameters. Moreover, an increase in flux recovery ratio and reduction of total fouling ratio indicated successfully enhancement of antifouling properties of membrane by coating of chitosan/GO nan-osheets.
