“…Following the carbonization (D), the surface became more irregular and smoother, but with the addition of cavities of varying sizes that are crucial for accommodating adsorbate molecules. The morphological structures of materials made from lignin and cellulose are typically irregular and disorganized, resembling the structure of fruit waste [ 34 , 44 , 45 ], forest seed species [ 46 , 47 , 48 ], and tree bark [ 49 , 50 , 51 ]. These irregularities are evenly distributed and contain cavities and voids that can significantly enhance adsorption [ 52 ].…”

This study explores the potential of the corozo fruit (Bactris guineensis) palm tree in the Colombian Caribbean as a source for porous carbon material. Its specific surface area, pore volume, and average pore size were obtained using N2 adsorption/desorption isotherms. The images of the precursor and adsorbent surface were obtained using scanning electron microscopy (SEM). Fourier transform infrared (FTIR) spectra were obtained to detect the main functional groups present and an X-ray diffraction analysis (XRD) was performed in order to analyze the structural organization of the materials. By carbonizing the fruit stone with zinc chloride, a porous carbon material was achieved with a substantial specific surface area (1125 m2 g⁻1) and pore volume (3.241 × 10−1 cm3 g⁻1). The material was tested for its adsorption capabilities of the drug propranolol. The optimal adsorption occurred under basic conditions and at a dosage of 0.7 g L⁻1. The Langmuir homogeneous surface model effectively described the equilibrium data and, as the temperature increased, the adsorption capacity improved, reaching a maximum of 134.7 mg g⁻1 at 328.15 K. The model constant was favorable to the temperature increase, increasing from 1.556 × 10−1 to 2.299 × 10−1 L mg−1. Thermodynamically, the adsorption of propranolol was found to be spontaneous and benefited from higher temperatures, indicating an endothermic nature (12.39 kJ mol⁻1). The negative ΔG0 values decreased from −26.28 to −29.99 kJ mol−1, with the more negative value occurring at 328 K. The adsorbent material exhibited rapid kinetics, with equilibrium times ranging from 30 to 120 min, depending on the initial concentration. The kinetics data were well-represented by the general order and linear driving force models. The rate constant of the general order model diminished from 1.124 × 10−3 to 9.458 × 10−14 with an increasing concentration. In summary, the leftover stone from the Bactris guineensis plant can be utilized to develop activated carbon, particularly when activated using zinc chloride. This material shows promise for efficiently adsorbing propranolol and potentially other emerging pollutants.

“…The most used in studies are the Langmuir [120] and Freundlich [121] equations; both are classified as isotherms, where their parameters are temperature dependent [122]. In the literature, it is possible to observe the successful application of these models to represent different adsorbents in removing pharmaceutical compounds [123][124][125].…”

Introduction: When using conventional methods to remove contaminants present in water, it generates limitations, such as low efficiency values, and the need for a large operating area added to a high operational cost. As a result, the scientific community has focused its efforts on improving existing removal methods, such as adsorption more focused on the use of biosorbents. These are generally zero-cost waste materials in nature that have a large volume, an example is those generated in agriculture, such as rice husks, peanut husks, cassava husks, and fruit husks, among others. Methodology: This study sought to carry out an extensive review through a broad database, providing biosorbents already produced and used to remove various contaminants. For certain contaminants such as dyes and some heavy metals, dead or live biomasses present promising removal results. The great advantage is that these materials generally present insufficient management, causing several environmental problems. Once used as biosorbents, they solve the problem of bioaccumulation and support the treatment of effluents, making the process sustainable. Results: The most satisfactory results were obtained in the removal of heavy metals, while the use of microbial biomass presented a lower performance, being more dependent on the control of nutrients and other parameters involving the process. The removal of other organic compounds presented greater complexity since they presented functional groups of varying ionic nature, which influence the interaction have the functional groups present on the surface of the biosorbent. Conclusions: Finally, Biosorption presents several advantages such as its cost-benefit, high effectiveness, easy implementation, and how fibrous residues are used, the active sites are freer to adsorb substances and chemicals. Added to this, it enables the use of waste which supports management, reducing environmental pollution resulting from incorrect disposal, making the process sustainable globally.
