ملخص المقالة :
در این مقاله، از اکسید گرافن برای حذف ۲-کلروفنل از محلول‌های آبی به روش جذب سطحی استفاده شد. به این منظور اثر پارامترهای مختلف از جمله غلظت اولیه ۲-کلروفنل، زمان تماس، pH اولیه محلول و مقدار جاذب بر روی حذف آن مطالعه شد. نتایج نشان داد که فرایند جذب سطحی در ۵۰ دقیقه به تعادل می‌رسد و مقدار حذف ۲-کلروفنل با افزایش مقدار جاذب ابتدا افزایش و سپس کاهش می‌یابد. از طرفی با افزایش غلظت اولیه ۲-کلروفنل و pH، درصد حذف ۲-کلروفنل کاهش یافت. مطابق نتایجg/L 3/0 از اکسید گرافن قادر به حذف %76/78 از ۲-کلروفنل در غلظت اولیه mg/L 100 و در 2pH = است. بنابراین اکسید گرافن جاذب پرقدرتی برای حذف ترکیب سمی ۲- کلروفنل از محیط‌های آبی می‌باشد.
