“…The most commonly employed adsorbent utilized to remove pharmaceuticals from aqueous effluents is activated carbon (de Oliveira Carvalho et al, 2010;Thue et al, 2018;Hanafy et al, 2021, Sellaoui et al, 2017, 2019 and other carbon-based adsorbents such as biochar (Tomul et al, 2020). On the other hand, different composite materials (Arif et al, 2022;Caicedo et al, 2020;dos Reis et al, 2016;Guellati et al, 2022;Khan et al, 2020;Kovtun et al, 2020;Lawal et al, 2019;Magesh et al 2022;Thue et al, 2020;Wang, Q et al, 2021;Yadav et al, 2021;Yu et al, 2018, Sellaoui et al, 2022 are used as alternatives to activated carbons.…”

Two carbon composite materials were prepared by mixing avocado biochar and methyl polysiloxane (MK). Firstly MK was dissolved in ethanol, and then the biochar was added at different times. In sample 1 (R1), the time of adding biochar was immediately after dissolving MK in ethanol, and in sample 2 (R2), after 48 h of MK dissolved in ethanol. The samples were characterized by nitrogen adsorption/desorption measurements obtaining specific surface areas (SBET) of 115 m² g -1 (R1) and 580 m² g -1 (R2). The adsorbents were further characterized using scanning electron microscopy, FTIR and Raman spectroscopy, adsorption of vapors of n-heptane and water, thermal analysis, Bohem titration, pHpzc, C H N elemental analysis. R1 and R2 adsorbents were employed as adsorbents to remove the antibiotic ciprofloxacin from the waters. The t1/2 and t0.95 based on the interpolation of Avrami-fractional-order were 20.52 and 246.4 min (R1) and 14.00 and 157.6 min (R2), respectively. Maximum adsorption capacities (Qmax) based on the Liu isotherm were 10.77 (R1) and 63.80 mg g -1 (R2) for ciprofloxacin. The thermodynamic studies showed a spontaneous and exothermic process for both samples, and the value of H° is compatible with physical adsorption.
