                         worldwide, indicating the need of alternative wastewater 
                         treatments. Activated hydrochar (AHC) is efficient for 
                         pharmaceuticals removal. Powdered AHC presents challenges that 
                         hamper its expansion. However, these issues can be overcome by 
                         adding polymers, such as alginate, in composite beads. Therefore, 
                         the present study aimed to develop and characterize 
                         alginate/brewer's spent grain AHC beads, applying them to 
                         acetaminophen adsorption in batch and fixed-bed experiments. The 
                         adsorbent presented a high surface area (533.42 m2 g1) and 
                         Fourier-transform infrared spectroscopy (FTIR) showed that 
                         alginate assigned new functional groups to the composite. Batch 
                         studies revealed an endothermic behavior and maximum adsorption 
                         capacity of 165.94 mg g\−1, with an equilibrium time of 240 
                         min. The fixed-bed maximum adsorption capacity was 127.01 mg 
                         g\−1, with a mass transfer zone of 5.89 cm. The importance 
                         of alginate for the adsorbent development has been successfully 
                         proven.",
