“…Biochar destiny after adsorption represents another strong point for its use for water purification. As reported by several authors [124,125], contaminated biochar could be a source of fertilizers, catalysis, metal nanoparticle synthesis through pyrolytic conversions, feed additives, and biologically active compounds.…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

The coexistence of multiple toxic water pollutants (heavy metals, organic dyes, oils, and organic solvents) limits the sustainable supply of clean water worldwide and urges the development of advanced water purification technology that can remove these contaminants simultaneously. Since its discovery, graphene‐based materials have gained substantial attention toward development of new‐generation sorbents for water purification. Despite several recently published reviews on water purification technology using graphene and its derivatives, there is still a gap in the review considering multiple water‐pollutant remediation using advanced graphene materials. In this review, in the first instance, a comparative structure–function–performance relationship between graphene‐based sorbents and the multipollutants in water is established. A fundamental correlation is made between the sorption performance for diverse pollutants in water with the more specific adsorption properties (surface area, pore size, type of functional groups, C/O, C/N, and C/S atomic ratio) of advanced graphene sorbents. Second, the underlying interaction mechanisms are uncovered between different classes of water pollutants using single graphene‐based sorbents. Third, the rational design of advanced multipollutant sorbents based on graphene is elaborated. The reality, challenges, and opportunities of advanced graphene materials as emerging sorbents for sustainable water purification technology are finally presented in the last section.

“…Debe considerarse que el biocarbón utilizado queda cargado generalmente con contaminantes tóxicos (colorantes, metales pesados, fármacos, etc. ), los cuales pueden causar otros problemas al medio ambiente como la contaminación del suelo, fauna y flora, e inclusive los cuerpos hídricos superficiales y subsuperficiales podrían verse afectados por lixiviación [49]. De modo que estos compuestos tóxicos serían nuevamente reincorporados a los diferentes compartimentos ambientales, en caso de que no se le dé un tratamiento adecuado al biocarbón obtenido tras el proceso de tratamiento de aguas [49].…”

El biocarbón es el producto procedente de la descomposición de biomasa, cuyas características fisicoquímicas están asociadas al origen de ésta y al método de combustión utilizado. Entre estas propiedades, destacan el área superficial, la formación de macro y microporos, y la presencia de grupos funcionales. Debido a estas características, el biocarbón se convierte en un material alternativo con alta capacidad de adsorción de compuestos tóxicos presentes en las aguas residuales contaminadas. Este trabajo brinda información sobre los mecanismos de generación del biocarbón y cómo éstos interfieren en sus características fisicoquímicas. Asimismo, se describen los parámetros que intervienen en los procesos de remoción de contaminantes y se mencionan los tratamientos bajo los cuales el biocarbón se puede ver sometido para mejorar su capacidad de adsorción. Finalmente, se indican los posibles usos o la adecuada disposición final que debe tener el biocarbón en aras de contribuir a la estrategia de economía circular.
