AB  - The presence of dyes in water is undesirable due to the toxicological impact of 
      their entrance into the food chain. Owing to the recalcitrant nature of dyes to 
      biological oxidation, a tertiary treatment like adsorption is required. In the 
      present study, unsaturated polyester resin (UPR) has been used as a sorbent in 
      the treatment of dye-contaminated water. Different concentrations of Tropaeoline 
      000 containing water were treated with UPR. The preliminary investigations were 
      carried out by batch adsorption to examine the effects of pH, adsorbate 
      concentration, adsorbent dosage, contact time, and temperature. A plausible 
      mechanism for the ongoing adsorption process and thermodynamic parameters have 
      also been obtained from Langmuir and Freundlich adsorption isotherm models. 
      Thermodynamic parameter showed that the sorption process of Tropaeoline 000 onto 
      activated carbon (AC) and UPR were feasible, spontaneous, and endothermic under 
      studied conditions. The estimated values for (DeltaG) are -10.48 x 10(3) and 
      -6.098 x 10(3) kJ mol(-1) over AC and UPR at 303 K (30  degrees C), indicating towards a 
      spontaneous process. The adsorption process followed pseudo-first-order model. 
      The mass transfer property of the sorption process was studied using Lagergren 
      pseudo-first-order kinetic models. The values of % removal and k (ad) for dye 
      systems were calculated at different temperatures (303-323 K). The mechanism of 
      the adsorption process was determined from the intraparticle diffusion model.
