چکیده

امروزه گسترش فناوری و توسعۀ فعالیت‌های صنعتی، سبب ورود مقادیر زیادی از آلاینده‌های مختلف به محیط‌های آبی شده است. ترکیبات سیانید از آلاینده‌های پساب صنایع مختلف به‌خصوص معادن طلا و نقره‌اند که به‌علت سمی بودن زیاد برای انسان و محیط زیست باید پیش از تخلیه به محیط تصفیه شوند. در این پژوهش، نانوذرات مغناطیسی سیلیکا مطابق روش هم‌رسوبی و استوبر با اندکی تغییر سنتز و با خاکستر برگ درخت زیتون تلخ اصلاح و قابلیت آن برای حذف سیانید از محلول‌های آبی بررسی شد. برای تعیین مشخصات نانوکامپوزیت سنتزشده از الگوی پراش پرتو ایکس، طیف‌سنج مادون قرمز تبدیل فوریه، میکروسکوپ الکترونی روبشی و مغناطیس‌سنج نمونۀ مرتعش استفاده شد. طرح آزمایش در این تحقیق به‌صورت یک عامل در یک زمان بود و تأثیر عوامل pH، مدت زمان تماس، مقدار جاذب و غلظت اولیۀ سیانید بررسی شد. براساس نتایج این پژوهش، در شرایط بهینۀ 5=pH، مقدار جاذب 750 میلی‌گرم بر لیتر، مدت زمان تماس 30 دقیقه و غلظت اولیۀ 50 میلی‌گرم بر لیتر سیانید، 81/41درصد این ماده حذف شد. بررسی مدل‌های ایزوترمی جذب از مدل لانگمویر با ضریب همبستگی 0/981 تبعیت می‌کند. همچنین بررسی سینتیکی جذب نشان داد که سرعت فرایند جذب یون‌های سیانید روی جاذب Fe3O4/SiO2 برازش بهتری با مدل سینتیکی شبه ‌مرتبۀ دوم دارد. این تحقیق نشان داد که نانوذرات مغناطیسی سیلیکای اصلاح‌شده با خاکستر برگ درخت زیتون تلخ قابلیت خوبی در جذب آلایندۀ سیانید در محلول‌های آبی دارند.

چکیده [English]

Today, the technology advancements and industrial developments have led large amounts of pollutants to make their way to aquatic environments. Cyanide compounds are a pollutant, found mainly in the gold and silver mines sewage, which should be refined due to high toxicity for human beings and the environment before discharging. In this study, silica magnetic nanoparticles were synthesized in the main accordance with the Stober method with a slight synthetic change and modified with bitter olive leaves ash; the aim was to assess the capability of the proposed method in the removal of the cyanide compounds from aqueous solutions. To determine the synthesized nanocomposite specifications, the following methods were used: X-ray diffraction pattern, Fourier transform infrared spectrometer, scanning electron microscopy, and parametric magnetometer. The experimental design in this study was one factor at a time and the effect of pH, the duration of contact, the amount of adsorbent, and the initial concentration of cyanide were investigated. Based on the results, up to 81.41% of the cyanide was excluded under the optimal conditions of PH at 5, absorbent amount of 750 mg /L, contact duration of 30 minutes, and initial concentration of 50 mg /L cyanide.  The results also revealed that the iso-thermic absorption models basically follow the Langmuir model with a correlation coefficient of 0.981. Conducting a traditional absorption study showed the speed of the absorption of the cyanide ions on Fe3O4/SiO2 adsorbent is better matched with a second-order kinetic model. Correspondingly, the study findings showed silica magnetic nanoparticles modified with bitter olive leaves ash are good in absorbing cyanide contaminants in aqueous solutions.
