Combination of SPE and pH adjustment for the simultaneous spectrophotometric de...
Ferreira, Francisca; Ribas, Tânia; Mesquita, Raquel; Rangel, AntónioCopper, zinc, and manganese are commonly found in both natural and treated water sources. Although these metals are essential micronutrients, their accumulation, even at low concentrations, can lead to serious health issues. Therefore, continuous and accurate monitoring of these elements in environmental and drinking water is crucial to ensure public safety. Solid Phase Extraction (SPE) is a widely used sample ...
Innovative water sampling strategy for the simultaneous sampling and sample pre...
Ribas, Tânia; Rodrigues, Francisco; Mesquita, Raquel; Rangel, AntónioThe content of certain metal ions in aquatic ecosystems has emerged as an environmental concern, posing significant risks to both aquatic life and human health. Some metal ions, including cadmium, are usually present at a trace level in environmental waters. Nevertheless, even at low exposure levels, cadmium can lead to serious health problems. Its increasing presence in natural waters is largely attributed to ...
Packed ionic resins to perform solid phase extraction (SPE) and solid phase spe...
Mesquita, Raquel; Pereira, Mafalda; Melo, Maria; Ribas, Tânia; Rangel, AntónioThe adverse effects in the environment of metal ions are well documented, notably for those displaying toxic effects for living organisms according to their concentration. Novel sampling and real-time monitoring methods will have a significant impact on understanding the spatial-temporal distribution of the metal ions and will contribute to act on-time to detect and mitigate sources of contamination of aquatic ...
Amostragem inteligente como abordagem expedita para monitorização de iões de me...
Pereira, Mafalda G.; Melo, Maria M. P.; Mesquita, Raquel B. R.; Ribas, Tânia; Machado, Ana; Rangel, António O. S. S.O projeto Aqua_Smart (FCT ref. 2022.08713.PTDC) foi concebido com o objetivo de desenvolver um conceito de amostragem inteligente integrada numa monitorização automática do teor de iões potencialmente tóxicos em águas, permitindo monitorizar alterações ambientais que podem ter impacto na saúde pública, promovendo uma abordagem “One Health”. Neste trabalho reporta-se a utilização de uma PIM como suporte de troca...
Bromelain-assisted bioactive peptide extraction from fish by-products
Borges, Sandra; Ribas, Tânia; Campos, Débora; Rosa, Ana; Almeida, André; Pintado, ManuelaMarine fisheries and aquaculture play a fundamental role in global food security, specifically with the rise in fish production and the United Nations' Sustainable Development Plan for 2030. However, fish processing generates significant by-products, including viscera, carcasses, heads, skin, and bones. Annually, over 20 million tons of fish tissue are discarded worldwide, accounting for about 70% of the total ...
O impacto intrafamiliar do diagnóstico da síndrome de Down: uma revisão integra...
Lima Filho, João; Guarinello, Ana Cristina; Ribas, Tânia; Paisca, Adriele Barbosa; Gonçalves, Flávio; Santos, Rosane SampaioO objetivo deste estudo é analisar, por meio de uma revisão de literatura, o que tem sido abordado acerca do impacto do diagnóstico de SD em famílias, por pesquisadores da área da saúde. Trata-se de um estudo de revisão integrativa de artigos publicados em periódicos, que apresentaram como conteúdo principal o impacto do diagnóstico de Síndrome de Down em famílias. Foram incluídos artigos publicados entre janei...
Greener and wide applicability range flow-based spectrophotometric method for i...
Ribas, Tânia; Mesquita, Raquel; Moniz, Tânia; Rangel, Maria; Rangel, António O. S. S.A flow-based method for the spectrophotometric determination of iron in recreational waters, both fresh and marine (variable salinity content), was developed. For that purpose, 3-hydroxy-4-pyrydinone ligand functionalized with an ether function was synthetized and used as chromogenic chelator (1-(3′-methoxypropyl)-2-methyl-3-benzyloxy-4-(1H)pyridinone - MRB13) for iron quantification. This water-soluble reagent...
