Adsorption of Dyes from Aqueous Solutions onto Multi-functional PPy/CS Exfoliated Nanohybrid for Fashionable Layered Polymer Nanocomposites

Autor: Hosny A. El-Daly, Rehab G. El Sharkawy, Beshoy T. Nasr, Nehal Salahuddin

Publikováno v: Recent Advances in Environmental Science from the Euro-Mediterranean and Surrounding Regions (2nd Edition) ISBN: 9783030512095

Wastewater treatment has become immensely challenging. Adsorption process has an obvious drawback since it does not lead to dyes degradation in the end. A novel Polypyrrole/Chitosan/exfoliated Grapheneoxide/Montmorillonite (PPy@CS/MMT/GO) nanohybrid

Kinetic investigation of the oxidative decolorization of Direct Green 28 and Direct Blue 78 by hydrogen peroxide

Autor: A. M. Habib, Mostafa A. Borhan El-Din, Hosny A. El-Daly

Publikováno v: Dyes and Pigments. 66:161-170

Environmentally, H 2 O 2 is a friendly oxidant. It is used in the current work to oxidize and decolorize two of the direct dyes that fulfill an outstanding demand. These dyes are C. I. Direct Green 28 (14155), I , and C. I. Direct Blue 78 (34200), II

Terbium–neodymium co-doping in Bi sites on the BPSCCO bismuth cuprate superconductor

Autor: Hosny A El-Daly, Morsy M.A. Sekkina, Khaled M. Elsabawy

Publikováno v: Superconductor Science and Technology. 17:93-97

The parent BiPbSr2Ca2Cu3O10 (BPSCCO) and samples of the general formula Bi1-(x+y)NdxTbyPbSr2Ca2Cu3O10, where x = y = 0.05, 0.1 and 0.2, were prepared using the conventional high-temperature solid-state reaction technique. The superconducting measurem

Kinetics and mechanism of the oxidative color removal from Durazol Blue 8 G with hydrogen peroxide

Autor: Mostafa A. Borhan El-Din, A. M. Habib, Hosny A. El-Daly

Publikováno v: Dyes and Pigments. 57:197-210

The kinetics of oxidation of the direct dye Durazol Blue 8G with H2O2 was studied spectrophotometrically in different media. An induction period was observed at the early stages of the reaction. The slowness of the oxidation reaction was a precursor

Kinetic Studies of the Oxidationof Coumarin-540 Laser Dye

Autor: Hosny A. El-Daly, Ali H. Gemeay, Tarek A. Fayed

Publikováno v: Monatshefte fuer Chemie/Chemical Monthly. 131:749-759

3-(2-Benzothiazolyl)-7-diethylaminocoumarin (C-540) has been irradiated at 254 nm in halomethane solvents, and the first order rate constant of the photo-oxidation reaction was determined. The hydrogen bond donation of the solvents plays a substantia
