چکیده

با گسترش روزافزون آلودگی­ ها، توجه به حذف و کاهش ورود آلاینده ­ها به محیط با روش‌هایی مقرون به‌صرفه و کارآمد ضروری می­ نماید. یکی از منابع اصلی آلوده‌کنندة بوم­ سازگان آبی عناصر با فرم ­های مختلف هستند، که برخلاف ترکیبات آلی از طریق فرآیندهای شیمیایی یا زیستی در طبیعت تجزیه نمی‌شوند و به­ طور جدی شبکه ­های غذایی و نهایتاً سلامت انسان را تحت تأثیر قرار می­ دهند. یکی از این ذرات روی می‌باشد که با توجه به دامنة تحمل متفاوت آبزیان، با حضور در محیط آبی اثرات متفاوتی را القا می‌نماید. مطالعة حاضر به ­منظور حذف نانوذرة شیمیایی، سبز و یون فلز روی در دو غلظت 1/5و 2/5 میلی­گرم در لیتر با استفاده از سیستم تصفیة تله­ ذره‌گیر Bit Trap Filter انجام شد. نمونه‌برداری­ ها در یک بازة زمانی سه ساعته و هر بیست دقیقه یکبار صورت گرفت. بازدهی کاهش غلظت نانوذره شیمیایی، سبز و یون فلزی روی در غلظت اولیه 1/5 میلی­ گرم در لیتر به‌ترتیب 98 درصد، 98/67درصد و 98/67 به­ دست آمد. بازدهی کاهش غلظت نانوذره شیمیایی، سبز و یون فلزی روی در غلظت اولیه 2/5 میلی­ گرم در لیتر به ترتیب 98/40درصد، 99/20 درصد و 98/40درصد به­ دست آمد. مطالعة حاضر به­ خوبی نشان داد که نانوذره شیمیایی، سبز و یون فلزی روی را می­ توان با استفاده از سیستم تصفیة تله‌ذره‌گیر از محیط آبی حذف نمود.

چکیده [English]

With the increasing spread of pollution, it is essential to focus on removing and reducing the entry of pollutants into the environment using cost-effective and efficient methods. One of the main sources of pollution in aquatic ecosystems is elements in various forms, which, unlike organic compounds, do not decompose in nature through chemical or biological processes and severely affect food webs and ultimately human health. Zinc is one such particle, which, given the varying tolerance levels of aquatic organisms, induces different effects in the aquatic environment. This study aimed to remove chemical, green, and ionic zinc nanoparticles at two concentrations of 1.5 and 2.5 mg/L using a Bit Trap Filter system. Sampling was performed over three hours, every twenty minutes. The efficiency of reducing the concentration of chemical, green, and ionic zinc nanoparticles at an initial concentration of 1.5 mg/L was 98%, 98.67%, and 98.67%, respectively. The efficiency of reducing the concentration of chemical, green, and ionic zinc nanoparticles at an initial concentration of 2.5 mg/L was 98.40%, 99.20%, and 98.40%, respectively. This study demonstrated that chemical, green, and ionic zinc nanoparticles can be removed from the aquatic environment using a Bit Trap Filter system.
