چکیده

6-4-2تری نیتروفنول از آلودگی­ های اصلی موجود در جریان پساب­ های صنایع پتروشیمی، نفت، داروسازی، پلاستیک و همچنین در مقادیر کمتر در فاضلاب شهری و کشاورزی یافت می­ شود. آلودگی اکوسیستم‌های آبی و آب آشامیدنی به این آلاینده باعث سمیت، مشکلات بهداشتی و طعم و بو می‌شود. هدف از این مطالعه حذف 2-4-6تری نیتروفنول از محلول آبی با استفاده از بیوکامپوزیت مغناطیسی پوسته خرچنگ پورتنوس سگنیس اصلاح‌شده است. به‌منظور بهینه­ سازی فرایند جذب2-4-6 تری نیتروفنول از نرم‌افزار دیزاین اکسپرت و روش پاسخ سطحی در طرح مرکب مرکزی استفاده شد. پارامترهای جذب مانند زمان تماس (10 تا 120 دقیقه)، pH (2-7)، غلظت اولیه تری­نیتروفنول (10 تا 60 میلی­ گرم بر لیتر) و میزان غلظت جاذب (10 تا 50 میلی­گرم) مورد بررسی قرار گرفتند. ایزوترم داده­ های تعادلی جذب با استفاده از مدل­ های ایزوترمی لانگمویر، فروندلیچ و تمکین بررسی شد. نتایج نشان داد در شرایط بهینه، کارایی حداکثر حذف2-4-6 تری نیتروفنول، 52 درصد با مقدار بهینه 3/25=pH، میزان غلظت جاذب 40 میلی گرم، غلظت اولیه 2-4-6تری نیتروفنول 22/5 میلی­ گرم بر لیتر و زمان 92/5 دقیقه به ­دست آمد. همچنین مطالعه مدل ایزوترم نشان داد جذب2-4-6 تری نیتروفنول بر روی جاذب از مدل لانگمویر با ضریب همبستگی (%86=R2) پیروی می­ کند و حداکثر ظرفیت جذب بر اساس مدل لانگمویر 59/88 میلی­ گرم بر گرم بوده است. نتایج این مطالعه نشان داد بیوکامپوزیت مغناطیسی پوست خرچنگ پورتنوس سگنیس اصلاح‌شده کارایی خوبی در حذف 2-4-6تری نیتروفنول دارد و درعین‌حال قیمت ارزان و دسترسی آسان سبب می ­شود که این بیوکامپوزیت به­ عنوان بیوجاذب مطلوبی مدنظر قرار گیرد.

چکیده [English]

Trinitrophenol is one of the major pollutants present in the effluents of petrochemical, oil, pharmaceutical and plastic industries, as well as in smaller amounts in municipal and agricultural wastewater. The aim of this study is to remove Trinitrophenol from aqueous solution using a modified Portunus segnis crab shell magnetic bio-composite. In order to optimize the adsorption process of Trinitrophenol, Design-Expert software and surface response method are used in the central composite design. The adsorption is evaluated by parameters of adsorbent dosage contact time (10 to 120 mins), pH (2-7), initial concentration of Trinitrophenol (10 to 60 mg / L) and adsorbent dosage (10 to 50mg). The equilibrium adsorption isotherms are analyzed using Langmuir, Freundlich and Tamkin isotherm models. The results show that under optimal conditions, the maximum removal efficiency of Trinitrophenol is attained 52% with an optimum value of pH = 3.25, the amount of adsorbent dosage is 40mg, the initial concentration of Trinitrophenol is 22.5mg per liter and the time is 92.5 minutes. Also, the study of the isotherm model show that the adsorption of Trinitrophenol on the adsorbent follows the Langmuir model with a correlation coefficient of (R2 = 86) and the maximum adsorption capacity based on the Langmuir model is 59.88mg per gr. The results of this study show that the modified Portunus segnis crab skin magnetic bio-composite has a good efficiency in removing Trinitrophenol, and at the same time its cheap price and easy access make this bio-composite to be considered a desirable biosorbent.
