In order to produce 1000 kg of leather, it is estimated of 85% of chemical input, used by European tanning plants, is discharged as contaminant. Among of them, Cr (VI), this is a toxic compound of easy adsorption. In that sense, the present work is focused on the removal of Cr (VI) in synthetic solution prepared from Cr (VI) estimated concentration found in wastewater sample discharged by tanning industries (Cr (VI): 32,6 mg/kg). Thus, five filters packed with orange (Citrus sinensis) and plantain (Musa AAB) peels were used in laboratory scale (Fa: 100% orange, Fb: 70% orange/30% plantain, Fc: 50% orange /50% plantain, Fd: 30% orange /70% plantain y Fe: 100% plantain). The main results show that among filters with the best performance in adsorption was Fd. Such filter had a removal efficiency of 93%, compare to Fa: 73%, Fb: 90%, Fc: 86% y Fe: 82%. Additionally, the adsorption constants found were between 96 and 132 mg Cr (VI)/gadsorb. Therefore, the combined bioadsorbents (plantain/orange peels) could be highly recommended for Cr (VI) removal in tanning effluents.
