چکیده

متیلن ﺑﻠﻮ رایج‌ترین ﻣﺎده رﻧﮕﯽ در جهان برای رﻧﮓ‌آمیزی پنبه، ﭘﺸﻢ و اﺑﺮیشم با مصرف زیاد است که در پساب صنایع نساجی به مقدار زیاد یافت می‌شود. در این پژوهش واکنش تجزیه فوتوکاتالیزگری متیلن بلو در پساب با استفاده از نانوکامپوزیت ZnFe2O4-ZnO-perlite  در حالت سوسپانسیون و تابش نورهای فرابنفش  و مرئی LED در فوتوراکتور ناپیوسته انجام شد. برای تهیه نانوکامپوزیت ZnFe2O4-ZnO-perlite، ابتدا ترکیب نانوگوی‌های ZnFe2O4 با استفاده از روش هیدروترمال سنتز شد. در ادامه، نانوذرات اکسید روی در محیط حاوی پرلیت و ZnFe2O4 با روش سل-ژل سنتز شد. برای شناسایی نانوکامپوزیت تهیه شده از تصاویر میکروسکوپ الکترونی روبشی، طیف سنجی تبدیل فوریه-زیر قرمز و همچنین الگوی پراش پرتو ایکس استفاده شد. تأثیر عوامل عملیاتی در تجزیه فوتوکاتالیزگری نظیر مقدار کاتالیزگر، توان لامپ‌های UV و مرئی LED، مدت زمان تابش و دمای واکنش بررسی شد و بیشترین کارایی در شرایط بهینه با مقدار نانو فوتوکاتالیزگر 3 گرم در لیتر، توان لامپ‌های فرابنفش و مرئی LED 20 وات، مدت زمان تابش 120دقیقه و دمای 35 درجه سلسیوس مشاهده شد. واکنش از نظر سینتیکی در شرایط بهینه بررسی شد و نتایج نشان داد که سینتیک آن شبه مرتبه اول بود و نتایج قابل قبولی در این بررسی‌ها به دست آمد. بر اساس این نتایج روشی برای تجزیه فوتوکاتالیزگری با استفاده از نانوکامپوزیت ZnFe2O4-ZnO-perlite به‌دست آمد که می‌‌توان با گسترش آن به شکل صنعتی، برای تجزیه پساب‌های رنگی در صنایع استفاده نمود.

چکیده [English]

Methylene blue is the most common colored material that is used to stain cotton, wool and silk; it has a high global consumption, and is found in high-tech textile wastewater. In this study, the photocatalysis degradation reaction of methylene blue (MB) in polluted water was performed using a ZnFe2O4-ZnO-perlite nanocomposite in suspension condition under UV and visible LED illumination in a batch photoreactor. To prepare ZnFe2O4-ZnO-perlite nanocomposite, first, ZnFe2O4 nanospheres were synthesized by hydrothermal route, ZnO nanoparticles were prepared via sol-gel method in media containing perlite and ZnFe2O4. To detect prepared nanocomposite, scanning electron microscopy (SEM) images, Fourier-transform infrared spectroscopy (FT-IR) and X-ray powder diffraction (XRD) pattern were used. Effects of operating factors on photocatalyst degradation such as catalyst amount, powers of UV and visible LED lamps, radiation duration and reaction temperature were investigated. The highest efficiency was obtained under optimal conditions (3 g/L photocatalyst amount, UV power and LED power of 20 watts, the radiation time of 120 minutes and temperature of 35 ºC). The kinetic reaction was investigated in optimal conditions and the results showed that its kinetics was first order and the results were acceptable in these studies. Based on these results, a method for photocatalytic degradation was obtained using a ZnFe2O4-ZnO-perlite nanocomposite, which can be used to expand it into industrial form, for wastewater treatment in industry.
