Arenas, Manuel Undabeytia López, Tomás Ministerio de Ciencia e Innovación (España) European Commission Agencia Estatal de Investigación (España) Póster presentado en XXII Meeting of the Spanish Society of Chromatography and Related Techniques 16-18 oct, 2023, Mallorca (España) Pyrolysis, heating biomass in the absence of oxygen, enables the conversion of biomass residues into biochar [1]. It is an aromatic carbonaceous material with high porosity and adsorption capacity, which can be activated and used in the production of filters that function similarly to commercial activated carbon (AC) filters. This study evaluates the adsorption capacity of biochar produced from rice husk (RH) and almond shell (AS) for the removal of emerging organic contaminants (EOCs) in water. This application could reduce the concentration of EOCs derived from pharmaceuticals and pesticides present in water, avoiding the use of activated carbons (AC) derived from fossil coal or imported from long distances. Additionally, it would reduce the implementation of pyrolysis and activation processes that pose high environmental risks and promote the recycling and valorization of low-value residual biomass. Biocarbons (BCs) were produced from RH and AS at pyrolysis temperature of 750 °C and were activated with steam or KOH (for comparative purposes). The elemental composition, physical properties, and iodine index of the BCs were determined before and after activation. Subsequently, their adsorption capacity of Sulfamethoxazole, Atenolol, Carbamazepine, Diclofenac, Salicylic Acid, and Acetaminophen were measured (n=3). These organic compounds represent cationic, anionic, and neutral pharmaceuticals and pesticides, some of which are currently considered as EOCs due to their frequent presence in hospital and wastewater effluents. For this purpose, 100 mg of each BC sample were mixed with 20 mL of a 10 mg L-1 solution of each contaminant, shaken for 24 hours and centrifuged. The contaminant concentrations in the supernatant were measured using high-performance liquid chromatography with a diode array detector (HPLC-DAD). The chromatographic column used was a reverse-phase C18 (Novapack, Waters Co.) with specific mobile phases for each contaminant. All the activated BCs were rich in organic carbon (> 75%), and their physical properties were suitable for its use as a filter, although the iodine number was notably lower than that of commercial AC. AS biochars showed slightly lower performance in terms of EOC removal, while the BCs from RH activated with steam exhibited a nearly 100% adsorption capacity for all tested contaminants, with better yields than commercial AC.
