The increasing consumption of antidepressants, aggravated by the coronavirus disease 2019 (COVID-19) pandemic, has resulted in the detection of compounds such as fluoxetine in drinking water. This substance is highly toxic to aquatic organisms and has the potential for bioaccumulation in aquatic environments. This study evaluated the effects of modifying natural zeolites through ion exchange to enhance their ad...
The combined approach of specific surface area (SSA), porosity, microprobe analysis (EMPA), transmission electron microscopy (TEM), scanning electron microscopy (SEM) equipped with EDX and infrared spectroscopy (FTIR) provided the mica mineral physico-chemical and morphological characterisation. The electrostatic surface properties were assessed through the determination of the Point of Zero Charge (pHPZC) by t...
A poluição das massas de águas superficiais e subterrâneas por fluoretos é uma questão ambiental preocupante. A qualidade da água para consumo humano pode ter efeitos adversos resultantes da ingestão de altas dosagens deste elemento, cujo excesso se deve às emissões por fontes naturais, industriais e até à implementação de políticas favoráveis à fluoretação artificial e sistémica das águas de abastecimento públ...
