چکیده

پایداری و شیمی سبز اکنون بخش جدایی‌ناپذیری از شیمی محیط زیست، علوم مواد و جاذب‌های آلودگی به ویژه آلودگی‌های نفتی هستند. امروزه مواد مزوپوری سهم مهمی در تصفیه آب دارند و مطالعات روش‌های بررسی آن ها و ایجاد رابطه میان این مطالعات در آزمایشگاه تا کاربرد در صنعت از اهمیت ویژه ای برخوردار است. آنالیزهای مربوط به سطح و حفره نقش بسیار مهمی در درک خواص مواد به عنوان جاذب دارند. در این میان برای مواد مزوپور ایزوترم بی جی اچ یکی از روش‌های متداول برای تحلیل و تعیین توزیع اندازه منافذ مواد مزومتخلخل است. این روش برای تعیین ویژگی‌های مواد بر اساس فرآیند جذب و دفع گاز در ساختارهای تخلخلی استفاده می‌شود. در این پژوهش که در راستای تحقیقات قبل است، جاذب هایی بر پایه پنبه که با چارکل و بنتونیت اصلاح سطحی شده اند مورد بررسی قرار گرفتند. ایزوترم‌های این جاذب‌ها نشان داد که در درجه اول خواص حفرات به مواد مزومتخلخل تعلق دارد و در درجه دوم اندازه منافذ کاملا با میزان حذف نمونه حقیقی آلودگی نفتی در محیط آبی در تعامل است. یافته‌های ما بینش‌های ارزشمندی در زمینه طراحی و بهینه‌سازی جاذب‌های مزومتخلخل برای کاربردهای عملی ارائه می‌دهند و نشان می‌دهند در این سیستمها میتوان از آنالیز بی جی اچ به عنوان یک معیار دقیق برای جذب آلاینده‌های نفتی استفاده کرد. این مطالعه گامی مهم به سوی توسعه روش‌های مقرون به صرفه و سازگار با محیط زیست برای پاکسازی آلودگی از آب با استفاده از مواد مزومتخلخل سبز است.

چکیده [English]

Sustainable chemistry and green chemistry are now integral components of environmentally-friendly materials science, pollution adsorption studies, and particularly research on oil pollutants. Mesoporous materials currently play a significant role in water purification, and extensive research is being conducted to analyze and characterize these materials' pore size distribution, from laboratory experiments to industrial applications. The Barrett-Joyner-Halenda (BJH) method is one of the most widely used approaches for this purpose. In this study, we investigated pumice-based sorbents modified with charcoal and bentonite. The results revealed that these sorbents have mesoporous characteristics, and their pore size distribution is significantly correlated with the actual sample's oil contaminant removal efficiency in an aqueous environment. These findings provide valuable insights into the design and optimization of mesoporous sorbents for practical applications. Moreover, the BJH analysis serves as an accurate criterion for oil contaminant adsorption in such systems. This study marks an important step towards the development of cost-effective, eco-friendly methods for oil pollutant purification from water using green mesoporous materials.
