Various concentrations of copper are embedded into silica matrix to xerogels form using copper source—Cu(NO3)2·3H2O. The xerogel samples are prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) with determination of new molar ratio of components by the sol–gel method....
The dosage of a collector is an important factor that determines the efficiency of a froth flotation process. The representative sample of the carbonatitic Palabora copper ore ground 45 % passing 75 µm was froth-floated with sodium isobutyl xanthate (SIBX) collector at 60, 70, 80, 90 and 100 g/t...
In the present study, different process intensification options in batch mode are considered for a class of reactions, and are evaluated with respect to enhancement in conversion and product purity considering methyl acetate formation reaction as an experimental case study. The options explored...
Corrosion inhibitive behavior of newly synthesized water soluble semiconducting polymer composite poly(vinyl alcohol–proline) (PVAP) is focused in this article. The polymer was characterized by FTIR, SEM-EDX, and XRD techniques. Thermogravimetry and differential thermal analysis proved the...
This paper deals with the synthesis of Sal oil methyl ester (SOME) biodiesel using Sal oil (Shorea robusta) and acidic ion-exchange resin catalyst (INDION-225 H). An experimental set-up was proposed for the synthesis of SOME biodiesel where esterification of free fatty acids and...
The zero-valent iron (ZVI) impregnated MCM-48 (Fe-MCM-48) as a new reagent was used to dechloronation of 2,4-dichlorophenol (2,4-DCP) pollutant. The Fe-MCM-48 was prepared by a grinding method as a solvent-free procedure. The X-ray diffraction patterns, SEM images and EDX spectra were applied to...
In this report, Dy2O3 (dysprosia) nanoparticles were prepared by using the combustion method. The innovative aspect of this method is preparation of dysprosium oxide nanoparticles without applying calcination temperature. To study the effect of the heating and annealing on the structure of...
