چکیده مقاله :
زمینه و هدف: توسعه شهرنشینی و صنایع، منجر به افزایش میزان فاضلاب و پساب تولیدی گردیده است. دفع ناقص و غیر اصولی این فاضلاب ها باعث ورود مقادیر زیادی فلزات سنگین به محیط زیست شده که حذف آن ها از آب و پساب به عنوان آلودگی هایی که از نظر زیستی تجزیه ناپذیرند، برای حفظ محیط زیست و سلامت عمومی بسیار مهم است. روش بررسی: در این مطالعه به سنتز و بررسی ساختاری گاما نانو آلومینا سنتز شده به عنوان یک جاذب با کارایی بالا در حذف فلزات سنگین نیکل و کبالت پرداخته شده و با استفاده از طراحی آزمایش با نرم افزار DX7 اثر شرایط متفاوتی از قبیل میزان غلظت اولیه فلزات سنگین، مقدار نانو جاذب و pH بررسی گردید. یافته ها: نتایج آنالیز XRD، FTIR، SEM و EDX ساختار گاما نانو آلومینا را تائید نموده و مقدار فلزات محتوی با روش اسپکتروفتومتری UV-Vis اندازه گیری شده است. نانو گاما آلومینا بعنوان یک جاذب قدرتمند قادر به جذب بالای نیکل و کبالت در محیط های آبی با pH قلیایی بوده به طوریکه در نمونه های آزمون، 66/98% نیکل و 1/95% کبالت و در نمونه های حقیقی نیز 100% آن ها حذف گردیده است. بحث ونتیجه گیری: با بررسی نتایج مشخص گردید که گاما نانو آلومینا سنتز شده می تواند به عنوان یک نانو جاذب مقرون به صرفه و کارا جهت حذف فلزات سنگین محسوب شود که این امر توسط ایزوترم های جذب فرندلیچ و لانگمویر مورد بررسی و تایید قرار گرفت و مشخص گردید که فرایند جذب (تک لایه ای یا چند لایه ای، یکنواختی یا ناهمگن بودن) این عناصر توسط جاذب نانوگاما آلومینا ، از معادله جذب فرندلیچ و لانگمویر پیروی می کنند.
Background and Objective: The development of urbanization and industries has led to an increase in sewage and wastewater production. The defective and non-standard disposal of these wastewaters has resulted in influx of large amounts of heavy metals into the environment which their removal, as bio-irresolvable contaminants, from water and wastewater are considerably important for protecting environment and public health. Method: In this study, gamma Nano-alumina was synthesized and its structural analysis was characterized, which was applied as a high performance adsorbent for heavy metals Nickel and Cobalt. Moreover, by using DX7 software for experiment design, the effects of different conditions such as heavy metals initial concentration, Nano-adsorbent amount and pH were modified. Findings: The results of XRD, FTIR, SEM and EDX analysis, confirmed the existence of gamma Nano-alumina structure, and Nickel and Cobalt contents were determined by UV-Vis spectrophotometry method. Nano gamma alumina, as a powerful adsorbent, could be adsorbed the high levels of Nickel and Cobalt in alkaline pH-rich environments, then in experimental samples, 98.66% of Nickel and 95.1% of Cobalt and in real samples, 100% was eliminated. Discussion and Conclusion: It was found that synthesized gamma Nano-alumina could be considered as a cost-effective and high-performance Nano-absorbent for heavy metals elimination. Consequently, it was verified by Freundlich and Langmuir adsorption isotherms, which the adsorption process of these elements with the Nano-alumina absorbent followed by Freundlich and Langmuir adsorption equation.
