چکیده

هدف از این تحقیق استفاده از روش فیلتراسیون توسط نانوفولرن اصلاح‌شده (C60) با تتراهیدروفوران، جهت حذف و کاهش فلزات سنگین مانند نیکل و کادمیم می‌باشد. شرایط بهینه برای حذف یون فلزات سنگین توسط نانوجاذب‌ها عبارتند از: pH، غلظت جذب شونده، مقدار جاذب، زمان و دما می‌باشد که برای هر دو یون مورد ارزیابی قرار گرفته است، نتایج نشان می‌دهد برای هر دو یون، شرایط بهینه جذب توسط نانوجاذب فوق، تقریباً یکسان بدست آمد. همچنین جذب سطحی هر دو یون با عدد اکسایش دو، توسط مدل‌های ایزوترم جذب بررسی گردید. نتایج نشان می‌دهد که بهترین ایزوترم جذب برای یون کادمیم، ایزوترم دابینین- رادوشکویچ و برای یون نیکل، ایزوترم فریندلیچ می-باشد. فرایند جذب برای هر دو یون، فیزیکی و بصورت تک لایه و گرمازا است. نتایج کلی نشان می‌دهند که نانوفولرن اصلاح شده دارای مقاومت حرارتی و مکانیکی بالایی‌ست و کاملاً پایدار بوده و می‌تواند بدون کم شدن فعالیت خود بیش از 20 بار با راندمان بالای 91% مورد استفاده قرار گیرد.

چکیده [English]

The aim of this study has investigated the removal and reduction of heavy metals such as nickel and cadmium by filtration of modified Nano-fullerene (C60) with tetrahydrofuran. The optimum conditions have been evaluated for the removal of heavy metal ions by nano-adsorbents, which are pH, adsorbent concentration, adsorbent amount, time and temperature. The results show optimum conditions for both ions are almost the same amount. The adsorption of both ions was investigated with the two-oxidation number by adsorption isotherm models. The results show that the best absorption isotherm for Cd2+ is Dobbin-Raduskvich isotherm and for Ni2+ is Freundlich isotherm. The absorption process for both ions is physical, monolayers and exothermic. The data show that the modified nanofullerene has a high thermal and mechanical resistance and is completely stable, which can be used for more than 20 times with high efficiency of %91 without losing its activity.
