Resumo
Introduction: Emerging contaminants refer to the extensive group of natural or synthetic substances that are frequently found in the ecosystem and that are not framed in any government monitoring program, presenting eminent risks to the health of humans and animals. Examples of emerging contaminants are pharmaceuticals, personal care products, and steroids, among others. The removal of these micropollutants can be achieved through adsorption resulting in improvements in water quality in terms of biodegradability and toxicity. Objective: Thus, the main objective of this work was to determine the best pyrolytic condition for the production of biochars from the Tingui barks for later, to be activated and applied in the adsorptive process of contaminants. Results: With this study it was possible to observe that the optimized pyrolysis condition for obtaining the best biochar from Tingui barks was at a temperature of 550ºC and with a retention time of 120 minutes. Under these conditions, the Tingui biochar presented the highest yield (32.0%) and fixed carbon content (75.0%). Conclusion: This makes it a promising biochar to be used in adsorption processes.
