In this study, the photocatalytic degradation of methyl orange and Congo red dye was investigated inaqueous solution using C,N,S-tridoped SnO2 nanoparticles as a nano photocatalyst. The degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand pH of the solution. The results indicated that the degradation of methyl orange and Congo redwas...

In this work, polypyrrole/CeO2 nanocomposite (NC) was synthesized in the presence of methylorange as a reactive self-degraded soft template. The field emission scanning electron microscopy(FESEM) images indicate that the CeO2 NPs have a nucleus effect and cause a homogenous PPycore–shell type morphology with an encapsulation of the CeO2 core by the PPy shell. The effect ofNC on acrylic waterbor...

Using hybrid chitosan-montmorillonite materials as environmentally-friendly alternatives to metallic salts in water treatment, and especially for drinking production, is a new challenge. However, the coagulation-flocculation process requires minimization of polymer release reactivity optimization guarantee low Dissolved Organic Carbon content treated waters. To meet these requirements, were des...

Three sensitive spectrophotometric methods are presented for the determination of finasteride in bulk and in tablets. The methods rely on the use of bromate-bromide reagent and three dyes namely, methyl orange, indigocarmine and thymol blue as reagents. They involve the addition of a measured excess of bromate-bromide reagent to finasteride in acid medium, and after the bromination reaction is ...

Oleuropein (OLE) is a major constituent of the olive leaf and green olives (Olea europaea). It has antioxidant and therapeutic properties and is valued as a medicinal component. The molecule is a complex phenolic compound constituted by a heterosidic ester of the elenolic acid and dihydroxy ethanol. This work concerns the determination of the inclusion complex constants between OLE and cyclodex...
