کاربرد نانو ذرات آهن صفر ظرفیتی برای بهبود پارامترهای مقاومت برشی خاک رس آلوده به گازوئیل

نوع مقاله : مقاله پژوهشی

چکیده

در سالهای اخیر نانوذرات آهن صفر ظرفیتی کاربرد های زیادی در تجزیه ترکیبات هیدروکربنی و پالایش سایر آلاینده ها داشته اند. اما تا کنون پژوهش مشخصی در مورد کاربرد آنها برای بهسازی خاک انجام نشده است. در این تحقیق از این نانو ذرات برای حذف گازوئیل از یک خاک رس آلوده استفاده شده و اثرات آن برحدوداتربرگ، تراکم و پارامترهای مقاومت برشی خاک بررسی شده است. نتایج نشان دهنده افزایش زاویه اصطکاک داخلی، چسبندگی، حداکثر دانسیته خشک و رطوبت بهینه خاک آلوده پس از اختلاط با نانو ذرات آهن می باشد. علاوه بر این، حد روانی و حد خمیری خاک کاهش یافته است.
