[ 1 ] - Removal of Congo Red Anionic Dye from Aqueous Solution Using Polyaniline/TiO2 and Polypyrrole/TiO2 Nanocomposites: Isotherm, Kinetic, and Thermodynamic Studies
The present study seeks to investigate the capacity of polyaniline/titanium dioxide (PAn/TiO2) and Polypyrrole/titanium dioxide (PPy/TiO2) nano-adsorbents to adsorb Congo red anionic dye (CR) from aqueous solution. The variables effective in CR adsorption, including adsorbent dose, pH of the solution, contact time, initial dye concentration, and temperature were examined. The study yielded the ...
[ 2 ] - Characterization of Polypyrrole-hydroxyethylcellulose/TiO2 Nanocomposite: Thermal Properties and AFM Analysis
Polypyrrole–hydroxyethylcellulose/TitaniumDioxide (PPy-HEC/TiO2) nanocomposite was synthesized via in situ chemical oxidative polymerization method at room temperature in water and water/ethyl acetate solution in the presence of ferric chloride (FeCl3). The effect of TiO2 nanoparticles and HEC on the characteristics of products such as thermal stability and morphology was investigated. The fabr...
[ 3 ] - Modification of Polyaniline/Polystyrene and Polyaniline/Metal Oxide Structure by Surfactant
Polyaniline/polystyrene (PAni/PS) composites were prepared in aqueous solution by polymerization of styrene and aniline in two-stages. Firstly styrene polymerize by using Ammonium persulfate (APS) as an oxidant in the presence of various surfactants such as poly(vinyl pyrrolidone) (PVP), hydroxypropylcellulose (HPC), poly(vinyl alcohol) (PVA) and surfactive dopant sodium dodecylbenzenesulfonate...
