AB  - In the current study, polyaniline and polypyrrole with silicon dioxide 
      (PAni:PPy@SiO(2)) were combined to formulate a new adsorbent, which was examined 
      using XRD, TEM, SEM, FTIR, TGA, and BET, and the adsorption kinetics were 
      investigated by UV-vis spectroscopy. The optical band gap was also evaluated. The 
      electrochemical behavior was investigated using cyclic voltammograms. Moreover, 
      experimental conditions were used to evaluate the 2,4-dichlorophenol (2,4-DCP) 
      adsorption based on the pH, temperature, reaction time, and initial 
      concentration. The analytical isotherm data were determined by Langmuir, 
      Freundlich, Temkin, Sips, and Redlich-Peterson models. For the analysis of the 
      kinetic data, the pseudo-first- and -second-order models and the intraparticle 
      diffusion model were investigated. It was found that this new adsorbent possessed 
      the highest adsorption efficiency after several regeneration cycles. Furthermore, 
      the thermodynamic parameters of adsorption, such as entropy (DeltaS), enthalpy (DeltaH), 
      and standard Gibbs were measured. These results suggest that the PAni:PPy 
      backbone can generally be better applied for the elimination of 
      2,4-dichlorophenol by appropriately dispersing it over the surface of suitable 
      SiO(2). This search provides a novel way to develop separable, high-performance 
      adsorbents for adsorbing organic contamination from wastewater.
