چکیده

رنگ‏زا‏ها از مهم‌ترین آلاینده‏های صنعتی راه‌یافته به محیط‏زیست به حساب می‏آیند و ازاین‏رو حذف آنها از پساب‏های صنعتی امری بسیار مهم است. در این میان ارائه روشی اقتصادی و با کارایی زیاد برای حذف رنگ‏زا مالاشیت سبز که از رنگ‏زا‏های بسیار سمّی برای محیط‏زیست و انسان است، مهم و ضروری است. در این پژوهش حذف رنگ‏زا مالاشیت سبز با استفاده از یک جاذب مقرون‌به‌صرفه و مؤثر بررسی شد که در راستای آن از کربن فعال حاصل از هسته خرما استفاده شد. کربن فعال حاصل از هسته خرما با استفاده از نانوذرات مغناطیسی Fe3O4 و اکسید کلسیم به روش رسوب‏دهی شیمیایی اصلاح شد. خواص و ویژگی‏های این سه جاذب با استفاده از آنالیزهای FTIR، VSM، TGA، XRD و SEM بررسی شد. پارامترهای مؤثر بر فرایند جذب از جمله pH، مقدار جاذب، زمان تماس و غلظت اولیه رنگ‏زا مالاشیت سبز بهینه‏سازی شدند. پژوهش‌های تعادلی و سینتیکی فرایند جذب با استفاده از مدل‏های رایج و مختلف انجام شد. نتایج به‏دست آمده نشان داد شرایط بهینه برای جذب رنگ‏زای مالاشیت سبز با استفاده از جاذب مورد بررسی عبارت است از: غلظت اولیه برابر با 10 میلی‏گرم در لیتر، pH برابر 7، زمان تماس برابر با 20 دقیقه، دوز جاذب برای AC، AC/Fe3O4 و AC/Fe3O4/CaO به‏ترتیب برابر با 3، 3 و 2 گرم بر لیتر. همچنین مدل فروندلیچ توانایی بیشتری برای توصیف رفتار تعادلی فرایند و مدل سینتیک شبه‌درجه دوم توانایی مناسبی برای بیان سینتیک واکنش دارد. بیشینه ظرفیت جذب تعیین شده با استفاده از مدل لانگمیر برای AC، AC/Fe3O4 و AC/Fe3O4/CaO به‏ترتیب برابر با 9/50، 7/85 و 4/107 میلی‏گرم بر گرم به‏دست آمد. توانایی واجذبی و استفاده مجدد AC/Fe3O4/CaO تا 8 مرحله بررسی شد که نتایج نشان داد جاذب‏ مذکور توانایی چندین مرتبه استفاده مجدد در فرایند جذب سطحی را دارد. نتایج نشان داد اصلاح کربن فعال با نانوذرات مغناطیسی Fe3O4 و اکسید کلسیم موجب افزایش بازدهی جذب آن می‌شود و آن ‏را به یک جاذب مناسب برای تجاری‌سازی تبدیل می‌‏سازد.

چکیده [English]

Dyes are one of the most important industrial environmental pollutants, and therefore their removal from industrial wastewater is very important. The malachite green is a very toxic dye for the environment and humans, therefore an economical and high-efficiency method to remove this dye from water solutions is necessary. In this study, the removal of malachite green was investigated using a economical and effective adsorbent, in which activated carbon from date kernel was used. Activated carbon from date kernel was modified by Fe3O4 magnetic nanoparticles and calcium oxide. The properties and characteristics of these adsorbents were investigated using FTIR, VSM, TGA, XRD and SEM analyzes. Parameters affecting the adsorption process such as pH, adsorbent dosage, contact time and initial concentration of malachite green were optimized. Equilibrium and kinetic study of adsorption process was performed using common models. The results showed optimal conditions for adsorption of malachite green using the adsorbent are: initial concentration equal to 10 mg/l, pH=7, contact time equal to 20 minutes, adsorbent dose for AC, AC/Fe3O4 and AC/Fe3O4/CaO equal to 3, 3 and 2 g/l, respectively. The Freundlich model also has a higher ability to describe process equilibrium behavior and the pseudo-second-order kinetics model has a good ability to express reaction kinetics. The Langmuir adsorption capacity of malachite green by the AC, AC/Fe3O4 and AC/Fe3O4/CaO was determined to be 50.9 mg/g, 85.7 mg/g and 107.4 mg/g respectively. The desorption and reuse ability of AC/Fe3O4/CaO was investigated up to 8 steps, which showed that the adsorbent has the ability to be reused several times in the adsorption process. The results showed that modification of activated carbon with magnetic Fe3O4 nanoparticles and calcium oxide increases its adsorption efficiency and makes it a suitable adsorbent for commercialization.
