Resumo
São muitos os desafios associados às microplásticos (MPs), destacando-se a sua presença e os seus efeitos prejudiciais tanto para a saúde humana como para o ambiente.Este trabalho apresenta uma possível solução proposta pela Captoplastic, uma tecnologia de captura e controlo de MPs em qualquer meio aquoso baseia-se na aglomeração e separação magnética das partículas, alcançando uma elevada eficiência de remoção. Além disso, é descrito um método patenteado pela Captoplastic S.L. (Captoplastic) para o controlo de MPs em qualquer amostra de água, abordando as limitações actuais das técnicas analíticas existentes, tais como a análise em amostras complexas. O estudo tem como objetivo determinar a presença e a concentração de MPs numa estação de tratamento de águas (ETAR). A metodologia utilizada é detalhada, desde a preparação da amostra até aos resultados experimentais, demonstrando a eficácia do método na deteção e quantificação de MPs em amostras reais de águas residuais, validando a recuperação destes poluentes em 96 %. Este avanço tecnológico é apresentado como uma resposta eficaz e promissora ao desafio global da poluição por MPs.
