AB  - In this work, pristine graphene oxide and its thermally reduced derivatives, rGO, 
      were tested for the removal of triazines (atraton, prometryn, and atrazine) from 
      water. The reduction process was optimized by means of design of experiments 
      (DOE) coupled with response surface methodology (RSM), relying on the adsorption 
      efficiency of the material. The optimal reduction conditions were calculated at a 
      temperature of 110  degrees C maintained for 24 h; the mildest and simplest reduction 
      protocol was chosen, as it allows in-air heat treatment with a common laboratory 
      oven. The rGO samples were characterized before use, confirming a partial 
      reduction process that, leaving intact most of the oxygenated functionalities on 
      the graphene skeleton, may still allow favorable adsorption of pollutants through 
      both hydrogen bonds and pi-pi interactions, which result from a large conjugated 
      polyaromatic system. Triazine analyses were performed by high-performance liquid 
      chromatography (HPLC); the data obtained from the adsorption isotherms were 
      fitted with the Langmuir and Freundlich models, highlighting a slightly different 
      adsorption behavior of atraton and prometryn compared with atrazine. Model 
      outcomes were also used to support the hypotheses about the adsorption process.
