چکیده مقاله :

زمینه و هدف: هر ساله میلیون ها تن مواد رنگی وارد پساب ها می شوند که این مواد از خطرناک ترین ترکیبات شیمیایی محسوب می شوند و حذف این مواد از پساب ها یک ضرورت است. هدف از این مطالعه بررسی و شناسایی امکان استفاده از جاذب بلوط مغناطیسی به عنوان یک جاذب کم هزینه برای حذف متیلن بلو از محلول های آبی است. روش و بررسی: با استفاده از آنالیز FTIR وجود آهن مغناطیسی در ساختار بلوط بررسی شد. در این کار از یک سیستم ناپیوسته برای انجام فرایند جذب استفاده شد و اثر pH، دوز جاذب، غلظت اولیه متیلن بلو، زمان تماس به عنوان پارامترهای کلیدی مورد بررسی قرار گرفت. همچنین مدل های ایزوترم مختلف جهت بررسی داده های آزمایشگاهی استفاده شدند. بافته ها: نتایج به خوبی نشان می دهد که افزایشpH باعث افزایش درصد حذف شده و بیشترین مقدار جذب در pH معادل 7 است. بررسی مدل های جذب نشان داد که ایزوترم های لانگمویر و Dubinin Radushkevich نسبت به مدل های دیگر تطابق بهتری با داده های آزمایشگاهی دارند. بررسی داده های سینتیکی نشان داد که داده ها از مدل شبه درجه دوم پیروی می کند. بحث و نتیجه گیری: این مطالعه به خوبی نشان داد که جاذب ارائه شده به خوبی قابلیت حذف رنگ را از پساب دارد. همچنین دارا بودن خاصیت مغناطیسی جاذب، سرعت احیا آن را سریع و راحت تر می کند.

چکیده انگلیسی:

Background and objective: Each year about billion tons of dyes from textile and dyeing industry are discharged in the wastewater, which they are the most dangerous chemicals. Then removing this dyes from wastewater requires proper treatment before being released into the environment. The aim of this study is to evaluate and determine the possibility of using absorbent obtained from the Fe3O4-Oak as a low-cost adsorbent for the removal of methylene blue from aqueous solution. Material and Methodology: FTIR analysis was used to investigate the presence of magnetite iron in the oak structure. In these tests, a batch system was used for the absorption process. The effect of pH, adsorbent dosage, and initial concentration of dye and time as key parameters were evaluated. Also, the isotherm models were used to study the experimental adsorption data. Findings: The results that increasing pH increases the removal rate and the highest adsorption was obtained at pH 7. The Langmuir, Freundlich, temkin and Dubinin–Radushkevich isotherm models were used to evaluate experimental data and obtained results indicated that the Langmuir isotherm and Dubinin–Radushkevich models is better than other models with data obtained. Finally, the results of this study indicate that used absorbent have high efficiency for removal of methylene blue. The pseudo-second-order kinetic model well depicted the kinetics of dyes adsorption on adsorbent. Discussion and Conclusion: This study has been showed that the present adsorbent has a good case for removing dye from wastewater and also, having the magnetic property of the adsorbent will cause more rapid regeneration.
