AB  - Water pollution caused by the release of organic pollutants is a major 
      environmental concern worldwide. These pollutants can have harmful effects on 
      aquatic ecosystems and the organisms living within them, as well as on human 
      health when contaminated water is consumed. It is essential to implement proper 
      treatment and management strategies to prevent and mitigate water pollution. 
      Moreover, the major untreated industrial effluents are synthetic organic 
      compounds especially 2,4,6-trichlorophenol (TCP) which cause several 
      environmental issues and heath related problems in humans. To cope with this 
      problem, an excellent 2D porous material based on p-DMAC4/GO composite has been 
      synthesized as adsorbent material for the effective removal of 
      2,4,6-trichlorophenol pollutant from wastewater. In this regard, the advanced 
      analytical tools such as Fourier-Transform infrared (FT-IR), X-ray Diffraction 
      (XRD), Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray 
      spectroscopy (EDS) were used for its characterization. The results justified the 
      chemical composition, excellent crystalline nature, surface morphology and 
      elemental composition of the synthesized composite material. The synthesized 
      adsorbent material showed 95% adsorption of TCP from wastewater system at optimal 
      conditions i.e., pH (6), adsorbent dosage (30 mg) and shaking time (60 min). The 
      mathematical models such as isotherms, thermodynamics and kinetics studies 
      validate the nature of adsorption process of TCP pollutant. The adsorption data 
      found to be best fitted with Langmuir isotherms (R(2) = 0.99); whereas kinetic 
      study suggested the pseudo-second-order nature of reaction with R(2) = 0.99. The 
      thermodynamics study confirmed the spontaneous and endothermic nature of the TCP 
      pollutant onto the surface of p-DMAC4/GO material. Moreover, the results of 
      current work were also compared with existing reported adsorbents and data 
      suggested the higher efficiency, feasibility, and reusability of p-DMAC4/GO 
      material to remove the TCP pollutant from the wastewater system.
