چکیده

توسعه تکنولوژی منجر به افزایش آلودگی ناشی از فلزات سنگین به دلیل سمیت بالا و اثرات مخرب بر سلامت انسان و محیط‌زیست شده است. روش‌های متعددی برای حذف فلزات سنگین از پساب‌ها وجود دارد. فلوتاسیون یونی، یک روش کارآمد، برای حذف یون‌های فلزات سنگین از محلول‌های آبی، با بازدهی بالا و هزینه عملیاتی پایین است. این روش توانایی بالقوه‌ای در حذف آنیون‌ها و کاتیون‌های معدنی و آلی دارد و به‌عنوان یکی از پیشرفته‌ترین فناوری‌های تصفیه آب محسوب می‌شود. در سال‌های اخیر، استفاده از نانوکلکتورهای گرافن اکساید و گرافن اکساید عامل‌دار شده در این فرآیند مورد توجه قرار گرفته است. این نانوکلکتورها به دلیل سطح ویژه بالا، پایداری مناسب، سنتز آسان، بازدهی بالا و امکان استفاده مجدد، عملکرد قابل توجهی در حذف یون‌های فلزات سنگین از پساب‌ها دارند. مطالعات نشان دادند که اصلاح سطح گرافن اکساید با گروه‌های عاملی مناسب، موجب بهبود انتخاب‌پذیری و افزایش بازدهی فلوتاسیون یونی می‌شود. این مقاله، به بررسی پیشرفت‌های اخیر در حذف یون‌های فلزات سنگین از پساب‌ها با روش فلوتاسیون یونی و همچنین به بررسی مکانیزم‌های جذب، تأثیر پارامترها و روش‌های بهینه‌سازی فرآیند فلوتاسیون یونی با استفاده از نانوکلکتورهای گرافن اکساید و گرافن اکساید عامل‌دار شده پرداخته و پیشنهاداتی برای تحقیقات آتی در زمینه نانوکامپوزیت‌های گرافن و جاذب‌های طبیعی ارائه می‌دهد.

چکیده [English]

The development of technology has led to an increase in heavy metal pollution due to their high toxicity and detrimental effects on human health and the environment. Various methods exist for the removal of heavy metals from wastewater. Among them, ion flotation is an efficient technique for the removal of heavy metal ions from aqueous solutions, offering high efficiency and low operational costs. This method has the potential to remove both inorganic and organic anions and cations, and it is considered one of the most advanced water treatment technologies. In recent years, the use of graphene oxide nanocollectors and functionalized graphene oxide in this process has attracted significant attention. These nanocollectors exhibit remarkable performance in removing heavy metal ions from wastewater due to their high specific surface area, good stability, ease of synthesis, high efficiency, and reusability. Studies have shown that surface modification of graphene oxide with appropriate functional groups improves selectivity and enhances the efficiency of ion flotation. This article reviews recent advances in the removal of heavy metal ions from wastewater using ion flotation. It also explores adsorption mechanisms, the influence of various parameters, and optimization methods for the ion flotation process using graphene oxide and functionalized graphene oxide nanocollectors, and offers suggestions for future research on graphene-based nanocomposites and natural adsorbents.
