Introdução: Os contaminantes emergentes referem-se ao extenso grupo de substâncias naturais ou sintéticas que são encontradas frequentemente no ecossistema e que não estão enquadrados em nenhum programa governamental de monitoramento, apresentando riscos eminentes à saúde dos seres humanos e animais. São exemplos de contaminantes emergentes os produtos farmacêuticos, de higiene pessoal e esteroides, dentre outros. A remoção desses micropoluentes pode ser obtida por meio da adsorção resultando em melhorias na qualidade da água em termos de biodegradabilidade e de toxidade. Objetivo: Desta forma, o objetivo principal desse trabalho foi determinar a melhor condição pirolítica para produção de biochars proveniente das cascas de Tingui para posteriormente, serem ativados e aplicados no processo adsortivo de contaminantes. Resultados: Com esse estudo foi possível observar que a condição otimizada de pirólise para obtenção do melhor biochar de cascas de Tingui foi em temperatura de 550ºC e com tempo de retenção de 120 minutos. Nestas condições, o biochar de Tingui apresentou o maior rendimento (32,0%) e o maior teor de carbono fixo (75,0%). Conclusão: O que consequentemente, o torna em um biochar promissor para ser empregado nos processos de adsorção.
