Improvement of the Homogeneous Fenton Reaction for Degradation of Methylene Blue and Acid Orange II

the survey of the virtual higher education in iran and the ways of its development and improvement

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.

Efficient Fenton like degradation of Methylene blue in aqueous solution by using Fe3O4 nanoparticles as catalyst

Fe3O4 nanoparticles were prepared hydrothermally and characterized by X-Ray diffraction spectroscopy (XRD), and scanning electron microscopy (SEM). It was found that these nanoparticles can act as an efficient catalyst in the degradation of Methylene blue dye in aqueous solution in a Fenton like system in presence of 30% perhydrol. Uv-Vis spectroscopy was used to determine the concentration of ...

Biochar from Orange (citrus sinensis) Peels by Acid Activation for Methylene Blue Adsorption

In this work, orange (Citrus sinensis) peels biochar (OPBC) were prepared by one-step H2SO4 activation for Methylene Blue (MB) adsorption from aqueous solution. The physicochemical properties of OPBC were characterized using instrumental analyses such as CHNS-O analyzer, Fourier Transform InfraRed (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), X-Ray Diffract...
