Abstract

This work proposes a facile methodology for producing porous biochar material (ABC) from acai kernel residue, produced by chemical impregnation with ZnCl2 (1:1) and pyrolysis at 650.0 degrees C. The characterization was achieved using several techniques, and the biochar material was employed as an adsorbent to remove catechol. The results show that ABC carbon has hydrophilic properties. The specific surface area and total pore volume are 1315 m(2)center dot g(-1) and 0.7038 cm(3)center dot g(-1), respectively. FTIR revealed the presence of oxygenated groups, which can influence catechol adsorption. The TGA/DTG indicated that the sample is thermally stable even at 580 degrees C. Adsorption studies showed that equilibrium was achieved in
