TL;DR: In this article, a comprehensive overview of the actual knowledge on the atmospheric pollution sources, transport, transformation and levels in the East Mediterranean is provided, focusing both on the background atmosphere and on the similarities and differences between the urban areas that exhibited important urbanization the past years: the two megacities Istanbul, Cairo and the Athens extended area.
Journal ArticleDOI
Applications of CTAB modified magnetic nanoparticles for removal of chromium (VI) from contaminated water
TL;DR: In this paper, the authors investigated the elimination of Cr(VI) from aqueous solution utilizing a composite from magnetic nanoparticles (Fe3O4) capped with cetyltrimethylammonium bromide (CTAB), which was examined by Fourier Transform Infra Red Spectroscopy (FTIR), X-ray Diffractometry (XRD), and Transmission Electron Microscopy (TEM).
Journal ArticleDOI
Spectrophotometric determination of sildenafil citrate in pure form and in pharmaceutical formulation using some chromotropic acid azo dyes
TL;DR: Two simple and highly sensitive spectrophotometric methods were developed for the quantitative determination of the drug sildenafil citrate, Viagra and the recovery study reveals that there is no interference from the common excipients that are present in tablets.
