Fluorescent ion-imprinted polymers for selective Cu(II) optosensing
(Springer HeidelbergHeidelbergAlemanha, 2012)
Study on soluble heavy metals with preconcentration by using a new modified oligosilsesquioxane sorbent
(Elsevier B.V., 2012-10-30)
In this work, a new modified oligosilsesquioxane was prepared, characterized and evaluated for its heavy metal adsorption characteristics from aqueous solution. The material was characterized using infrared spectroscopy, ...

Microbial nanocellulose adherent to human skin used in electrochemical sensors to detect metal ions and biomarkers in sweat
(2020-10-01)
The pursuit of biocompatible, breathable and skin-conformable wearable sensors has predominantly focused on synthetic stretchable hydrophobic polymers. Microbial nanocellulose (MNC) is an exceptional skin-substitute natural ...
Sensor arrays to detect humic substances and Cu(II) in waters
(ELSEVIER SCIENCE SA, 2009)
The interaction between poly(o-ethoxyaniline) (POEA) adsorbed onto solid substrates and humic substances (HS) and Cu(2+) ions has been investigated using UV-vis spectroscopy and atomic force microscopy (AFM). Both HS and ...
Nanocomposites based on LbL films of polyaniline and sodium montmorillonite clay
(Elsevier B.V., 2015)
Simultaneous determination of copper, mercury and zinc in water with a tailored fluorescent bipyridine ligand entrapped in silica sol-gel
(Springer HeidelbergHeidelbergAlemanha, 2010)
Automated two-dimensional separation flow system with electrochemical preconcentration, stripping, capillary electrophoresis and contactless conductivity detection for trace metal ion analysis
(WILEY-BLACKWELL, 2011)
This paper describes the automation of a fully electrochemical system for preconcentration, cleanup, separation and detection, comprising the hyphenation of a thin layer electrochemical flow cell with CE coupled with ...
Seleção de Enterococcus sp. resistente a cobre e a mercúrio com potencial aplicação na biorremediação
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia AmbientalUTFPR, 2016-11-21)
The presence of heavy metals can occur naturally or as a consequence of anthropogenic activities. Mercury is one of the most toxic elements, since copper is an essential micronutrient for all living things, but in large ...
