Electrokinetic and adsorption properties of sepiolite modified by 3-aminopropyltriethoxysilane.
Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. An investigation was carried out on the surface modification of sepiolite with aminopropylsilyl groups in 3-aminopropyltriethoxysilane (3-APT). The zeta potential of the modified sepiolite suspensions was measured as a function of initial elec...
متن کاملSpectrophotometric determination of ceterizine hydrochloride with Alizarin Red S.
A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer. The chromogen being extractable with chloroform, could be measured quantitatively at 440 nm. All variables were st...
متن کاملElectrochemical Sensor for the Determination of Alizarin Red-S at Non-ionic Surfactant Modified Carbon Nanotube Paste Electrode
The Cyclic Voltammetric (CV) behavior of Alizarin Red-S (ARS), which is an Anthraquinone dye was examined by utilizing TX-100 modified carbon nanotube paste electrode (TX-100MCNTPE). The surfactant utilized is TX-100, and it has been found that it has good electrocatalytic activity towards ARS. Distinctive parameters like pH, scan rate, detection limit have been studied in the potential range o...
متن کاملSynthesis and application of Amberlite xad-4 functionalized with alizarin red-s for preconcentration and adsorption of rhodium (III)
A new chelating resin was prepared by coupling Amberlite XAD-4 with alizarin red-s through an azo spacer, characterized by infra-red spectroscopy and thermal analysis and studied for Rh(III) preconcentration using inductively coupled plasma atomic emission spectroscopy (ICP-AES) for rhodium monitoring in the environment. The optimum pH for sorption of the metal ion was 6.5. The sorption capacit...
متن کاملPerformance Evaluation of Nano-silica Modified Bitumen
In this study, different contents of Nano-silica, 2 wt.%, 4 wt.% and 6 wt.%, have been added to bitumen to modify the physical, mechanical and rheological properties of warm mix asphalt (WMA). WMA is containing 2 wt.% of Sasobit (mixture of long-chain hydrocarbons). Various quality control tests have been carried out to characterize the modified bitumen and WMA. The rheo...
