“…The band at approximately 3000-3700 cm −1 is attributed to the stretching of O-H bonds (phenols, alcohols, and carboxylic acids) and the stretching of the -NH amine groups of the lignin [55]. The two bands at 2913-2923 and 2849 cm −1 are related to the symmetric and asymmetric stretching of the -CH 3 and -CH 2 groups or the -C-OH group [56,57]. In both activated carbons, there was a decrease in the intensity of these peaks, suggesting a lower amount of these groups on the surface compared to the treated samples.…”

In this study, ryegrass straw agricultural residue (Lolium multiflorum L.) was employed as an adsorbent material to remove methylene blue (MB) dye from aqueous solutions. Four adsorbents were produced using phosphoric acid and pyrolysis as activating agents. The samples were analyzed with TGA, FTIR, SEM, and XRD techniques. A rapid adsorption of the MB was obtained with the ryegrass treated with 40% H3PO4, reaching equilibrium in 2 min. Moreover, a maximum adsorption capacity of 80.79 mg g−1 and a removal efficiency of 99% were achieved. The results demonstrate a good performance of adsorbents from ryegrass for removing dye contaminants, such as methylene blue, from the aqueous solutions.

Pharmaceutical compounds present in liquid effluents have great environmental impact. Thus, the development of alternative adsorbent materials from agro‐industrial activities has received attention. This work aimed to adsorb ibuprofen onto activated carbon from olive pomace and evaluate the parameters of the adsorption system. The experiments were performed in batch and continuous flow. The mathematical models that best described the experimental data were the pseudo‐second‐order and Langmuir models for kinetic and isothermal studies. The fixed bed experiments showed a good fit for the Thomas model.
