چکیده

امروزه به دلیل افزایش رشد جمعیت و همچنین افزایش تقاضای انسان‌‌ها، صنایع گوناگون به شدت در حال رشد و توسعه هستند که این موضوع باعث کاهش آب‌های خالص شده و در نتیجه لزوم بازیافت آب‌‌ها در اولویت قرار گرفته است. مواد رنگزا ترکیبات آلی پیچیده‌ای هستند که در صنایع مختلف از آنها استفاده می‌‌شود. نانو ساختارهای چارچوب‌‌های آلی-فلزی مغناطیسی می‌‌تواند به عنوان یک ماده اصلی برای توسعه پایدار و حذف آلاینده‌‌های زیست‌محیطی استفاده شود. این چارچوب‌‌ها به دلیل حضور نانو ذرات مغناطیسی، هوشمند عمل کرده و با استفاده از یک میدان مغناطیسی متناوب خارجی جمع آوری شده و این مواد جاذب  قابلیت بازسازی مجدد و احیا دارند. با استفاده از این کامپوزیت‌‌های مغناطیسی می‌‌توان آلودگی‌‌ها را در محیط کنترل و جداسازی کرد. نانو ساختارهای چارچوب‌‌های آلی-فلزی مغناطیسی به دلیل سنتز و جداسازی آسان و دارا‌بودن دو رفتار جذبی و تخریبی، مساحت سطح بالا، واکنش سریع آنها با مواد رنگزای آلی و بازده بالا، نسل جدیدی از مواد را برای تصفیه پساب‌‌های صنعتی به وجود آورده‌‌اند. در این مطالعه سعی شده است که نانو ساختارهای چارچوب‌‌های آلی-فلزی مغناطیسی و همچنین کاربرد آنها به عنوان نانو جاذب برای حذف مواد رنگزای آلی از پساب‌‌های صنعتی بررسی شود.

چکیده [English]

Todays, due to increasing population growth as well as increasing human demand, various industries are growing rapidly, which has led to a decrease in clean water, and as a result, the need to recycle water has become a priority. Dyes are complex organic compounds that are used in various industries. The nanostructures of magnetic metal-organic frameworks can be used as the main material for sustainable development and the elimination of environmental pollutants. These frameworks are intelligent due to the presence of magnetic nanoparticles and have been collected using an alternating external magnetic field, which can be reconstructed and regenerated. These magnetic composites can be used to control and isolate contaminants in the environment. The nanostructures of magnetic metal-organic frameworks, due to their easy synthesis and separation and their two attractive and destructive behaviors, high surface area, their rapid reaction with organic dyes and high efficiency, give a new generation of materials to industrial effluent treatment. In this study, an attempt has been made to investigate the nanostructures of magnetic metal-organic frameworks as well as their application as nano sorbents to remove organic dyes from industrial effluents.
