Autor: Loubna Youssef, Ghassan Younes, Rami Al-Oweini
Publikováno v: Journal of Taibah University for Science, Vol 13, Iss 1, Pp 274-279 (2019)
An elegant and eco-friendly photocatalytic degradation approach for the most commonly used herbicide, Atrazine (ATZ); allowed a selective and partial degradation into atrazine-2-hydroxy (Hydroxyatrazine, HAT), which was the sole obtained metabolite.

Synthesis and Structure of Hexatungstochromate(III), [H3CrIIIW6O24]6–
Autor: Wenjing Liu, Zhengguo Lin, Bassem S. Bassil, Rami Al-Oweini, Ulrich Kortz
Publikováno v: CHIMIA, Vol 69, Iss 9 (2015)
The hexatungstochromate(III) [H3CrIIIW6O24]6- (1) was synthesized in aqueous, basic medium by simple reaction of chromium(III) nitrate nonahydrate and sodium tungstate dihydrate in a 1:6 ratio. Polyanion 1 represents the first Anderson-Evans type he

Vanadium-Substituted Polyoxomolybdates for Methylene Blue Adsorption from Aqueous Solutions
Autor: Mohammad H. El-Dakdouki, Ghassan Younes, Rami Al-Oweini, Roula Abi Saad
Publikováno v: Journal of Cluster Science. 33:2077-2083
The objective of this study is to assess the effectiveness of three vanadium-substituted polyoxomolybdates, [PMo11VO40]4−, [PMo10V2O40]5−, and [PMo9V3O40]6−, for the removal of methylene blue dye (MB) from aqueous solutions. The materials were
