A nafion film cover to enhance the analytical performance of the CuO/Cu electrochemical sensor for determination of chemical oxygen demand
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-06)
Article
Open AccessWe modified and evaluated the performance of a CuO/Cu electrochemical electrode for chemical oxygen demand (COD) determination by covering it with a Nafion (Nf) film. The resulting modified CuONf/Cu electrode sensor was ... -
Antimony removal from water by a chitosan-Iron(III)[ChiFer(III)] biocomposite
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-01)
Article
Open AccessThe presence of antimony(III) in water represents a worldwide concern, mainly due to its high toxicity and carcinogenicity potential. It can be separated from water by the use of sustainable biopolymers such as chitosan ... -
Neodymium recovery by chitosan/iron(III) hydroxide [ChiFer(III)] sorbent material: Batch and column systems
(2018-02-19)
Article
Open AccessA low cost composite material was synthesized for neodymium recovery from dilute aqueous solutions. The in-situ production of the composite containing chitosan and iron(III) hydroxide (ChiFer(III)) was improved and the ... -
Sorption of Hg(II) and Pb(II) ions on chitosan-iron(III) from aqueous solutions: Single and binary systems
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-03-25)
Article
Open AccessThe present work describes the study of mercury Hg(II) and lead Pb(II) removal in single and binary component systems into easily prepared chitosan-iron(III) bio-composite beads. Scanning electron microscopy and energy-dispersive ...
