Photocatalytic degradation of an organophosphorus pesticide using a ZnO/rGO composite

PHOTOCATALYTIC DEGRADATION OF THE ORGANOPHOSPHORUS PESTICIDE FENTHION IN AQUEOUS SUSPENSIONS OF TiO2 UNDER UV IRRADIATION

In present study the photocatalytic degradation of the organophosphorus pesticide fenthion, under UV irradiation in the presence of titanium dioxide (TiO2) photocatalyst, in aqueous suspensions has been investigated and compared with the photodegradation by hydrogen peroxide (H2O2) solution as an oxidant agent. The experiments were carried out in a 250mL pyrex UV laboratory-constructed photorea...

Photocatalytic degradation of an organophosphorus compound by porous Au- and WO3- modified TiO2

Photocatalytic degradation of methyl orange using TiO2:Mg2+/zeolite composite under visible light irradiation

Photodegradation of methyl orange was investigated using synthesized TiO2:Mg2+/zeolite as the photocatalyst. The photocatalyst was characterized by X-ray, XRF, FT-IR, and SEM. The photocatalytic activities of TiO2:Mg2+/zeolite samples were evaluated in the degradation of methyl orange under visible light irradiation. The appropriate content of Mg in the composite was obtained as 4.711 wt% with ...

High efficient degradation of Cefixime using UV/TiO2 photocatalytic process: A comparison between photocatalytic and photolytic

Introduction: The existence of pharmaceuticals in aquatic ecosystem, their persistence and possible effects on living organisms and inefficient systems in removal of these compounds from water and wastewater are a growing concern. In this research, the UV/TiO2 photocatalytic degradation of Cefixime was investigated so as to identify if this method was efficient for removal of Cefixime or not. ...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
