AB  - The release of textile effluent into the natural waters poses a serious threat to 
      the aquatic ecosystem. Here, SnO(2)/GO nanocomposites were synthesized with 
      tunable morphology by the addition of GO with a sonochemical method. The material 
      was characterized using X-ray Diffraction (XRD), scanning electronic microscopy 
      (SEM), Ultraviolet-visible spectroscopy (UV-vis), and infrared spectrometry (IR). 
      The photocatalytic degradation of Rhodamine B (RhB) and textile dye wastewater 
      (TDW) using SnO(2)/GO nanocomposites was studied under sunlight irradiation. The 
      SnO(2)/GO nanocomposites exhibited high photocatalytic activity towards the 
      degradation of RhB and TDW with up to 95% removal efficiency. The catalyst 
      dosage, concentration variation, and reusability of the catalyst were also 
      examined to optimize the reaction conditions for the degradation of dye. 
      Bioassays were used to investigate the survival growth rate of simple food webs 
      such as Chlorella pyrenoidosa (CP), Artemia salina (AS) and Danio rerio (DR) in 
      the treated and untreated solution. These simple food web model animals showed 
      good reliability for analyzing the toxicity of the treated and untreated 
      wastewater. Further, histology was analyzed to find out the influence of the dye 
      solution in the animal model. These results suggest that the SnO(2)/GO 
      nanocomposite shows promising efficiency in the wastewater treatment, which is 
      further confirmed in the toxicity analysis.
