چکیده

در این پژوهش، پودرهای تک فاز فریت کبالت (CoFe2O4) توسط روش سنتز احتراق محلولی با استفاده از نیترات های فلزی به عنوان اکسنده و گلایسین به عنوان سوخت در مقادیر متفاوت نسبت مولی سوخت به اکسنده (f) برابر با 5/0، 75/0، 1 و 25/1 تهیه شدند. ساختار، مورفولوژی و مساحت سطح ویژه پودرهای فریت کبالت احتراق یافته توسط روش هایی چون پراش پرتو ایکس، میکروسکوپ الکترونی روبشی، جذب-واجذب نیتروژن ارزیابی شدند. با افزایش مقدار سوخت، مساحت سطح ویژه و حجم تخلخل به ترتیب از 285 به m2/g 35 و 38/1 به cm3/g 17/0 کاهش یافتند. پودرهای فریت کبالت احتراق یافته به عنوان جاذب برای حذف یون کادمیم از محلول آبی استفاده شدند. بررسی زمان تماس نشان داد که سینتیک فرآیند جذب از مدل شبه مرتبه دوم پیروی می کند. ایزوترم های جذب به خوبی بر مدل فردلیچ منطبق شدند و بیشترین میزان ظرفیت جذب ( mg/g 694) توسط پودرهای فریت کبالت احتراق یافته در نسبت مولی سوخت به اکسنده برابر با 75/0 بدست آمد.

چکیده [English]

Cobalt ferrite (CoFe2O4) powders were successfully prepared by solution combustion synthesis using metal nitrates as oxidant and glycine as fuel at various fuel to oxidant molar ratios (f=0.5, 0.75, 1 and 1.25). The structure, morphology and specific surface area of as-combusted CoFe2O4 powders were characterized by X-ray diffraction, scanning electron microscopy and nitrogen adsorption-desorption techniques. By increasing of fuel content, the specific surface area and pore volume decreased from 285 to 35 m2/g and 1.38 to 0.17 cm3/g, respectively. The as-combusted magnetic CoFe2O4 powders were used as adsorbent for removal of Cd(II). The effect of the contact time showed the kinetics of adsorption process followed the pseudo-second-order model and was controlled by film diffusion process. The adsorption isotherms were also well fitted on the Freundlich model. The as-combusted CoFe2O4 powders at f=0.75 exhibited excellent adsorption capacity (694 mg g−1) and high adsorption rate.
