“…An adsorption capacity of 141.82 µg g -1 was observed at 10° C (283K) and which decreased along with an increase in temperature to 75.34 µg g -1 at 50° C (323K) under equilibrium conditions. Previously, similar results were observed for diclofenac adsorption on Isabel grape bagasse (Antunes et al, 2012) and for the removal of other pharmaceuticals on carbon black (Cuerda-Correa et al, 2010). In these studies, authors explained this phenomenon based on two processes: the energy exchange between sorbate, sorbent and the solvent and the solubility of pharmaceuticals.…”

Biochars were prepared from feedstocks pinewood and pig manure. Biochar microparticles obtained through grinding were evaluated for the removal of emerging contaminant diclofenac (DCF) and the underlying mechanism were thoroughly studied. Characterization of biochar was carried out using particle size analyzer, SEM, BET, FT-IR, XRD, XPS and zeta potential instrument. Pig manure biochar (BC-PM) exhibited excellent removal efficiency (99.6%) over pine wood biochar (BC-PW) at 500 µg L of DCF (environmentally significant concentration). Intraparticle diffusion was found to be the major process facilitated the adsorption. BC-PW followed pseudo first-order kinetics whereas BC-PM followed pseudo second-order kinetics. Pine wood biochar was largely affected by pH variations whereas for pig manure biochar, pH effects were minimal owing to its surface functional groups and DCF hydrophobicity. Thermodynamics, presence of co-existing ions, initial adsorbate concentration and particles size played substantial role in adsorption. Various isotherms models were also studied and results are presented.

“…However, its relatively high cost and difficult regeneration processes have to be faced with. Activated carbon prepared from agricultural by-products (biochar) is being investigated [10,17] for this purpose. One alternative to activated carbon focuses around natural and modified clays that have been considered for the removal of organic compounds from water systems [13].…”

The adsorption of fluoxetine onto activated carbons (ACs) prepared from almond tree pruning by steam and CO 2 activation under different temperature conditions (650-9508C), was studied. In both series increasing the temperature caused an increase in the BET apparent surface area, yielding ACs with S BET up to 870 and 710 m 2 g À1 after steam and CO 2 activation, respectively. Also, a slight widening of the porosity was found in both cases. In order to modify the functionality of the ACs, two of them were impregnated with triethylenediamine (TEDA) prior to the adsorption process, which caused a decrease in the AC apparent surface mainly due to micropore blockage. The fluoxetine adsorption isotherms at 258C showed maximum adsorption capacities between 110 and 224 mg g À1 . The adsorption isotherms were analyzed using Langmuir and Freundlich models. Although the impregnation reduced the pore volume, it did not cause a decrease in the fluoxetine maximum adsorption capacity, but a modification in the adsorption mechanism was observed.
