[ 1 ] - Extraction and Determination of Cyproheptadine in Human Urine by DLLME-HPLC Method

Novel dispersive liquid-liquid microextraction (DLLME), coupled with high performance liquid chromatography with photodiode array detection (HPLC-DAD) has been applied for the extraction and determination of cyproheptadine (CPH), an antihistamine, in human urine samples. In this method, 0.6 mL of acetonitrile (disperser solvent) containing 30 µL of carbon tetrachloride (extraction solvent) was ...

[ 3 ] - 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...

[ 4 ] - 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...

[ 5 ] - Electrochemical Oxidation of Flavonoids and Interaction with DNA on the Surface of Supramolecular Ionic Liquid Grafted on Graphene Modified Glassy Carbon Electrode

The study of the interaction between DNA and small molecules such as drugs is one of the current general interest and importance. In this paper, the electrochemical investigation of the interaction between some flavonoids such as rutin, quercetin, and hesperidin with dsDNA on the surface of Supramolecular Ionic Liquid grafted on the Graphene Oxide Modified Glassy Carbon Electrode (</s...
