Removal of amoxicillin from simulated hospital effluents by adsorption using activated carbons prepared from capsules of cashew of Para

摘要: High-surface-area activated carbons were prepared from an agroindustrial residue, Bertholletia excelsa capsules known as of Para cashew (CCP), that utilized for removing amoxicillin aqueous effluents. The with the proportion CCP:ZnCl2 1:1, and this mixture was pyrolyzed at 600 (CCP-600) 700 °C (CCP700). CCP.600 CCP.700 characterized by CHN/O elemental analysis, hydrophobic/hydrophilic ratio, FTIR, TGA, Boehm titration, total pore volume, surface area. These analyses show adsorbents have different polar groups, which confers a hydrophilic surface. presented area volume 1457 m2 g−1 0.275 cm3 g−1 (CCP.600) 1419 m2 g−1 0.285 cm3 g−1 (CCP.700). chemical physical properties very close, indicating pyrolysis temperature does not bring relevant differences in these adsorbents. adsorption data kinetics equilibrium successfully adjusted to Avrami fractional-order Liu isotherm model. use treatment simulated hospital effluents, containing organic inorganic compounds, showed excellent removals (up 98.04% 98.60% CCP.700).
