N2 - In this study, two bioadsorbents were developed by the pyrolysis from orange peel waste at 500°C and 700°C, respectively. Both biochars were characterized and evaluated for the treatment of a real raw textile industry wastewater from Medellin-Colombia. Additionally, the pollutant removal efficiency of synthesized biochars was compared with a commercial activated carbon (CAC). Synthetized materials showed no important variations between them in terms of chemical composition, mor-phology, structure, and textural properties. The maximum removal percentages for color, chemical oxygen demand, biochemical oxygen demand and total organic carbon were found be 32%, 30%, 68% and 52%, respectively, for the biochar obtained at 700°C under optimal conditions (100 mg of biochar at 25°C and pH of 3.0). The removal percentages for the same parameters under similar adsorption conditions were 22%, 15%, 14% and 27%, respectively, using the CAC. It is noticed that all values are smaller than those achieved with the bioadsorbents produced in this study. Thus, bio-adsorbents from orange peel waste could be an alternative low-cost material for treatment of real raw textile industry wastewater.
