| چکیده | ||
| دراین کار تحقیقاتی نانو کامپزیت SnO2-Zn2SnO4 با روش حالت جامد ساخته شد. خصوصیات این نانو ذرات با تکنیکهای مختلف از قبیل اسپکتروسکوپی پرتو ایکس و میکروسکوپ نشر الکترون بررسی شد. سپس یک حسگر الکتروشیمیایی برای اندازه گیری پیریدیم با استفاده از این نانو ذرات ساخته شد. این حسگر خواص الکترو کاتالیست بسیار عالی برای اندازه گیری پیریدیم نشان داد. پیک اکسایش این دارو در محدوده 0.3 تا 607.0 میکرومولار از پیریدیم خطی است. حد تشخیش 0.009 میکرومولار برای این روش پیشنهاد شد. این روش پیشنهادی بسیار انتخاب گر و ساده با دقت بالا برای اندازه گیری پیریدیم در نمونه های دارویی و مایعات بیولوژیکی است. | ||

| چکیده [English] | ||
| The SnO2-Zn2SnO4 nanocomposite was successfully prepared via a simple solid state method. The resulted nanocomposite was characterized by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Then, a novel pyridium sensor has been developed based on SnO2-Zn2SnO4 nanocomposites modified carbon paste electrode (SnO2-Zn2SnO4/CPE). The fabricated sensor exhibits outstanding electrocatalytic activities toward the oxidation of pyridium. The oxidation peak current was proportional to the concentration of pyridium from 0.3 to 607.0 µM with a detection limit of 0.009 µM at signal to noise ratio of 3. The proposed method was examined as a selective, simple and precise method for voltammetric determination of pyridium in real samples with satisfactory results. | ||
