| چکیده | ||
| حذف فلزات سنگین از پساب‌ها یکی از چالش‌های اساسی در چند دهه اخیر بوده و فرآیند فلوتاسیون یونی یکی از روش‌های موثر بوده است. فلوتاسیون یونی مزایایی همچون سادگی، نیاز به انرژی کم، بازیابی و انتخاب پذیری بالا نسبت به سایر روش‌ها و غلظت بسیار کم فلز باقیمانده در محلول را دارد ولی از معایب آن، مصرف زیاد کلکتور است. هدف از این مطالعه، حداکثر بازیابی یون منگنز و حداقل مصرف کلکتور است. در این مطالعه، گرافن اکساید تهیه شده به عنوان نانوکلکتور، توسط آنالیزهای XRD، DLS، FTIR و SEM شناسایی شد. پارامترهای موثر شامل pH، غلظت گرافن اکساید به عنوان نانوکلکتور اصلی، دبی هوا، سرعت همزن و غلظت سدیم دودسیل سولفات به عنوان کلکتور کمکی بود. نتایج نشان داد که pH بهینه برای حذف یون منگنز از پساب سنتزی با فلوتاسیون یونی حدود 10 است و سایر مقادیر بهینه پارامترهای غلظت نانوکلکتور، دبی هوا، سرعت همزن و غلظت سدیم دودسیل سولفونات به ترتیب برابر با ppm 25، rpm 800، L/min 2 و ppm 43 است. در این شرایط، درصد حذف یون منگنز از پساب سنتزی و بازیابی آب به ترتیب برابر با 82/6 و 45 درصد بدست آمد. نتایج نشان داد که استفاده از گرافن اکساید به عنوان نانوکلکتور در فرآیند فلوتاسیون یونی برای تصفیه پساب‌ها، مزایای قابل توجهی مانند بازیابی حذف بالا، کاهش مصرف کلکتور، قابلیت استفاده مجدد از گرافن اکساید و موارد مشابه را دارد. | ||

| چکیده [English] | ||
| Removing heavy metals from wastewater has been one of the main challenges in recent decades, and the ion flotation process has been one of the most effective methods for heavy metals removing. The advantages of ion flotation are its simplicity, requiring less energy, having high recovery and selectivity, and by a low concentration of residual metal in the solution. One drawback of ion flotation is the collector's high consumption. The purpose of this study is to enhance the recovery of manganese ions while minimizing the consumption of collectors. In this study, graphene oxide (GO) prepared as a nanocollector was identified by XRD, DLS, FTIR, and SEM analyses. The effective parameters included pH, GO concentration, air flow rate, impeller speed, and SDS concentration as an auxiliary collector. The results indicated that a pH of approximately 10 is the most effective for removing Mn ions from synthetic wastewater using ion flotation. Other optimal parameters of nanocollector concentration, air flow rate, impeller speed, and SDS concentration are equal to 25 ppm, 800 rpm, 2 L/min, and 43 ppm, respectively. Under these conditions, the recovery of Mn ions from synthetic wastewater and water recovery were 82.6% and 45%, respectively. The results of this study demonstrated that utilizing GO as a nanocollector in the ion flotation method for wastewater treatment has significant advantages such as high removal recovery, reduction of collector consumption, and reusability of GO. | ||
