زمینه و هدف: اﻓﺰاﯾﺶ ﻣﯿﺰان ﻓﺴﻔﺎت در ﻣﺤﯿﻂ ﻫﺎی آﺑﯽ ﺗﻮازن رﺷﺪ ﻣﻮﺟﻮدات آﺑﺰی را ﺑﻪ ﻫﻢ ﻣﯽ زﻧﺪ و ﻣﺸﮑﻼت زﯾﺴﺖ ﻣﺤﯿﻄﯽ ﺟﺪی را اﯾﺠﺎد ﻣﯽ ﮐﻨﺪ. در این مطالعه هدف بررسی آزمایشگاهی حذف یون فسفات با استفاده از نانوذرات اکسیدگرافن می باشد. روش بررسی: جاذب مورد استفاده در این تحقیق گرافن بوده که ابتدا به سنتز اکسید گرافن توسط مدل هامر پرداخته شد.جاذب سنتز شده به دلیل دارا بودن گروه های عاملی اپوکسی و هیدروکسیل بر روی سطح خود موجب می شود که خاصیت آب دوست بودن آن افزایش یابد و منجر به ارتقاء کاربرد اکسید گرافن در محیط های آبی شود.اثر پارامترهای مختلف شامل مقدار جاذب، pH، غلظت اولیه، دما و زمان تماس بر روی میزان جذب بررسی شد. هم چنین در ادامه مطالعات سینتیکی بر روی داده ها انجام گردید. یافته‌ها: بیش ترین درصد جذب برابر با 75% بوده است که در 3= pH و بعد از سه ساعت تماس محلول با جاذب اتفاق افتاده است. هم چنین نتایج نشان می دهد که داده ها متناسب با مدل سنتیکی شبه مرتبه دوم بوده است. اطلاعات آزمایشگاهی با مدل لانگمیر تطبیق داده شد. بحث و نتیجه‌گیری: با ﺗﻮﺟﻪ ﺑﻪ ﻧﺘﺎﯾﺞ ﺑﻪ دﺳﺖ آﻣﺪه جاذب اکسید گرافن به عنوان جاذب سازگار با محیط زیست ﺗﻮاﻧﺎﯾﯽ ﻣﻄﻠﻮﺑﯽ در حذف ﻓﺴﻔﺎت دارد .
