[ 1 ] - مطالعه مقایسه ای روی سرعت تخریب فوتوکاتالیستی تتراسایکلین با استفاده از نانو ذرات ZnS و Cu-loaded ZnSحساس شده به نور مرئی

نانو ذراتZnS و Cu-loaded ZnS حساس شده به نور مرئی با استفاده از روش ترسیب شیمیایی سنتز شد که در این سنتز از رنگ طبیعی آنتوسیانین به عنوان حساس کننده و بازدارنده رشد استفاده شد. از تکنیکهای XRD و TEM و UV-Vis جهت شناسایی و بررسی ویژگی های ساختاری نانو ذرات استفاده شد. سپس اثر فوتوکاتالیستی این نانو ذرات در تخریب تتراسایکلین مورد مقایسه و سنجش قرار گرفت و میزان تخریب فوتوکاتالیستی تتراسایکلین توس...

[ 2 ] - Synthesis of ZnO-nanoparticles by microwave assisted sol-gel method and its role in photocatalytic degradation of food dye Tartrazine (Acid Yellow 23)

ZnO- nanoparticles with an average particle size of 24 nm were successfully synthesized using the microwave assisted sol- gel technique. Structural and morphological properties of the nanoparticles were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy disperse spectrum (EDS) and Fourier transform infrared spectroscopy (FTIR). The band gap ene...

[ 7 ] - Validation of an Analytical Method for Simultaneous Determination of 18 Persistent Organic Pollutants in Trout Using LLE Extraction and GC-MS/MS

Persistent organic pollutants, (POPs), are vast distributed compounds in environment which are recognized as one of the global pollution problems. These groups of materials being dangerous due to their high stability are accumulated in animal tissues and occurring in the food chain. One of the major paths through which persistent organic combinations access to human body is consuming polluted f...
