Application of Electrocoagulation Process for Reactive Red 198 Dye Removal from the Aqueous Solution

Abstract Background and purpose:The main objectives of this research were to evaluating the application of electrocoagulation process for 198 dye from the aqueous phase and determining the optimum operating conditions to the dye removal using aluminum and iron electrodes. Materials and Methods:The present study was conducted in bench-scale. The spectrophotometer DR 5000 was used to determine th...

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 ...

A Kinetic Study on Adsorption of Congo Red from Aqueous Solution by ZnO-ZnFe2O4-polypyrrole Magnetic Nanocomposite

In this work, magnetically separable ZnO-ZnFe2O4-PPy nanocomposite as an efficient adsorbent was synthesized by two steps. At first, zinc oxide (ZnO) and ZnFe2O4 nanoparticles were synthesized using simple and facile precipitation method. Then, ZnO-ZnFe2O4 mixed oxide was modified by polypyrrole (PPy). The adsorbent was character...

Synthesis, Characterization and Adsorption Capability of CdO Microstructure for Congo Red from Aqueous Solution

Cadmium oxide rhombus-shaped nanostructure was synthesized using hydrothermal process followed by heating treatment. Clearly, X-ray diffraction pattern demonstrated the formation of CdO crystalline phase. Scanning electron microscopy (SEM) showed that the obtained rhombus-like structure is composed of nanoparticles with the average size of 29 nm. In addition, we evaluated adsorption of org...
