A persistência, a toxicidade e a baixa biodegradabilidade dos corantes sintéticos em sistemas aquáticos constituem um desafio ambiental relevante. Este estudo avaliou a adsorção do violeta cristal (CV) utilizando biomassa do tronco de Moringa oleifera no estado bruto (Tr) e após ativação química como carvão (CAT). As propriedades superficiais foram caracterizadas por meio do ponto de carga zero e da microscopia eletrônica de varredura. O desempenho de adsorção foi analisado com isotermas de Langmuir e Freundlich e modelos cinéticos de pseudo-primeira e pseudo-segunda ordem. Os resultados evidenciaram maior capacidade e eficiência no CAT. A cinética do Tr se ajustou ao modelo de pseudo-segunda ordem, enquanto que, para o CAT, não se obteve um ajuste conclusivo. A Moringa oleifera ativada é proposta como um adsorvente sustentável e eficiente para a remoção de corantes catiônicos da água.
