Sorption behavior of vanadium on silica gel modified with tetrakis(4-carboxyphenyl)porphyrin.
Tetrakis(4-carboxyphenyl)porphyrin (TCPP) has been loaded on aminopropyl-silica gel by physical adsorption and by direct immobilization through formation of an amide bond to obtain chelating sorbents. These sorbents have been studied for preconcentration and separation of vanadium prior to its determination by atomic absorption spectrometry. Several parameters, such as sorption capacity of the ...
متن کاملReverse phase partition chromatographic separation of vanadium with N-n-octylaniline on silica gel
A selective, sensitive, less expensive and more precise method was developed for the separation of vanadium [VO] using Nn-octylaniline (liquid anion exchanger) coated silica gel as stationary phase. The quantitative extraction of vanadium was found with 0.065 mol/L N-n-octylaniline and 0.009 to 0.02 mol/L of sodium malonate at pH 10.5. The extracted vanadium ion was eluted from the column with ...
متن کاملSynthesis and photocatalytic activity of nanosized modified mesocellulous silica foams (MCFs) with PW12 and vanadium oxide
A series of tungestophosphoric acid and vanadium oxide supported on Mesocellulous Silica Foams (MCFs) featuring a well-defined three-dimensional (3D) mesoporosity were studied with regard to their performance in the photocatalytic activity to degrade Oezine Y (OY). This nanosized mesoporous catalyst (PW12@V-MCF) was characterized by FTIR, XRD, BET and TEM. XRD shows that the structure of MCF re...

متن کاملMechanisms and Kinetics for Sorption of CO2 on Bicontinuous Mesoporous Silica Modified with n-Propylamine
We studied equilibrium adsorption and uptake kinetics and identified molecular species that formed during sorption of carbon dioxide on amine-modified silica. Bicontinuous silicas (AMS-6 and MCM-48) were postsynthetically modified with (3-aminopropyl)triethoxysilane or (3-aminopropyl)methyldiethoxysilane, and amine-modified AMS-6 adsorbed more CO(2) than did amine-modified MCM-48. By in situ FT...
