| در تحقیق حاضر به بررسی حذف فلزات سنگین (به صورت موردی حذف کبالت) از آب آلوده با استفاده از نانوذرات مغناطیسی Fe3O4 و بررسی تأثیر فاکتورهای pH، زمان ماند، غلظت اولیه کبالت و دما بر روی حذف کبالت پرداخته شده و برای توصیف داده‌های حاصل از آزمایشات جذب از ایزوترم‌های تعادلی لانگمویر و فروندلیچ استفاده شده است. آزمایش‌ها با روش تاگوچی در نرمافزار کوآلیتک که از روش فاکتوریل جزئی استفاده می‌کند، طراحی گردید. نانوذرات با روش هم‌رسوبی در آزمایشگاه سنتز شده و سپس آزمایش‌ها برای چهار سطح از هر فاکتور بر روی محلول شبیه‌سازی شده حاوی کبالت انجام می‌گردد و نتایج با کمک نرمافزار کوآلیتک به روش تحلیل استاندارد تاگوچی مورد آنالیز قرار گرفته می‌شوند. بالاترین میزان جذب کبالت برابر با 81 درصد، در حالت pH برابر با 9، زمان ماند 15 دقیقه، غلظت اولیه کبالت برابر با 7 میلیگرم بر لیتر و دمای °C 60 می‌باشد. همچنین با توجه به تحلیل، شرایط بهینه در حالت pH برابر با 9، زمان ماند 10 دقیقه، غلظت اولیه کبالت برابر با 25 میلیگرم بر لیتر و دمای °C 20 می‌باشد. میزان بازدهی در جذب کبالت 383/86 درصد پیش‌بینی می‌شود. در انتها نتیجه آزمایش در شرایط بهینه بر روی پساب صنعتی واقعی حاوی 36 میلیگرم بر لیتر کبالت 60 با درصد جذب 6/71 همراه می‌باشد که با توجه به تغییر در شرایط آزمایشگاهی و واقعی دارای اختلاف 11/17 درصدی می‌باشد. داده‌های حاصل از بررسی ایزوترهای جذب با دو مدل فوق مطابقت داشته و برازش بیشتری نسبت به مدل فروندلیچ دارد. | ||

| چکیده [English] | ||
| In the present study, the removal of cobalt ions from water by magnetic nanoparticles of Fe3O4 was investigated as a function of pH, time, cobalt ions concentration, and temperature. The design of experiments was performed using Taguchi fractional factorial method to study the effect of these factors at 4 levels on the performance of the nanoparticles synthesized by the co-precipitation technique. Data were analyzed by Coalition software and adsorption experiments were described based on Langmuir and Freundlich equilibrium isotherms. The highest adsorption rate (81%) was achieved at a cobalt initial concentration of 7 mg/l, a temperature of 60 °C, pH of 9, and residence time of 15 minutes. Considering the results of data analysis the optimum process conditions were found to be as follows: pH 9, residence time 10 minutes, cobalt initial concentration 25 mg/ L, and temperature 20 °C. The efficiency of cobalt adsorption was estimated to be 86/383%. The results of experiments on real industrial wastewater containing 36 mg/l cobalt 60 obtained under optimal conditions showed an adsorption efficiency of 71.6%. This indicates a drop of 17.11% that is attributed to the difference between experimental and actual conditions. The data obtained from adsorption isotherms were consistent with the two systems in question and best fitted to the Freundlich model. | ||
