چکیده
دنیا با بحران جهانی کیفیت آب روبه­رو است. رشد جمعیت، شهرنشینی و صنعتیشدن مصرف آب شیرین را تشدید کردهاست. حذف ترکیبات نفتی مضر از آب‌ها درپی تخلیه‌های صنعتی امروزی، برای محافظت از انسان، موجودات آبزی، حفظ کیفیت آب و جلوگیریاز آسیب‌های زیست‌بوم ناشیاز آلاینده‌ها ضروری است. هدف اصلی این پژوهش، جداسازی ترکیبات نفتی از آب بهروش غشایی بااستفاده‌از غشای پلیمری کیتوسان سنتزشده از پوست میگو و غشای ماتریس ‌مخلوط کیتوسان اصلاح‌شده‌است. از پوست میگو برای تهیۀ کیتوسان استفادهشد و سپس، غشای ماتریس مخلوط کیتوسان اصلاح‌شده‌با نانوذرات دی‌اکسید تیتانیم و استات سلولز سنتزشد. مدول غشایی از جنس تفلون ساختهشد و سامانۀ غشایی طراحی و ساختهشد. عملکرد پنج غشای مختلف ساختهشده با نام­ های M1 و M2 و M3 و M4 و M5 بررسی‌شد که متغییرهای عملیاتی مورد نظر عبارت‌است از: غلظت ورودی نفت، میزان نانوذرات در غشاهای سنتزشده و فشار عملیاتی. بهمنظور بررسی فرایند شاخص‌های شار عبوری و میزان حذف آلایندۀ نفتی بهعنوان پاسخ درنظرگرفتهشد. باتوجهبه مقایسۀ میان پنج غشای سنتزشده، غشای M3 حاوی سه‌درصد نانوذره با درصد حذف 8/94 در فشار 3 بار و برای خوراک با 10 درصد حجمی نفت، بهترین عملکرد را داشتهاست.

چکیده English

The whole world is facing a global water quality crisis. Population growth, urbanization, and industrialization have accelerated the consumption of fresh water. The removal of harmful oil compounds resulting from today's industrial discharges in waters is necessary to protect humans, aquatic organisms, and water quality and prevent ecological damage caused by pollutants. The main goal of this research is to separate petroleum compounds (oil) from water using chitosan polymer membrane synthesized from shrimp shells and modified chitosan mixed matrix membranes. Shrimp shells were used to prepare chitosan and then the mixed matrix membrane of chitosan modified with titanium dioxide nanoparticles and cellulose acetate was synthesized.
The performance of five different membranes made with the names M1, M2, M3, M4, and M5 was investigated, and the desired operating variables are oil inlet concentration, amount of nanoparticles in the synthesized membranes, and operating pressure. To investigate the process, the parameters of the water flux and the amount of oil pollutant removal were considered as the answer. According to the comparison between the five synthesized membranes, the M3 membrane containing 3 % of TiO2 nanoparticles with a removal percentage of 94.8% at 3 bar pressure, and 10% (v:v) of oil had the best performance.
