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, morphology, 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, bioadsorbents from orange peel waste could be an alternative low-cost material for treatment of real raw textile industry wastewater.
