Ionic liquids as additives for acid leaching of copper from sulfidic ores
(Elsevier, 2016-05)
Two acid imidazolium-based Ionic liquids (ILs) were evaluated for use in the leaching of a real non-concentrated chalcopyrite ore in an aerated system at different temperatures, monitoring copper recoveries in aqueous ...
Ionic medium effects on equilibrium constants .1. Proton, copper(II), cadmium(II), lead(II) and acetate activity coefficients in aqueous solution
(Elsevier B.V., 1996-10-01)
The molar single ion activity coefficients associated with hydrogen, copper(II), cadmium(II) and lead(II) ions were determined at 25 degrees C and ionic strengths between 0.100 and 3.00 M (NaClO4), whereas for acetate the ...
Improving the performance of a glucose biosensor using an ionic liquid for enzyme immobilization. On the chemical interaction between the biomolecule, the ionic liquid and the cross-linking agent
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The effect of the room temperature ionic liquid (1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([BMMI][BF4])) on the immobilization of glucose oxidase (GOx) was studied. The electrochemical performance of biosensors ...
Removal of copper ions using sodium hexadecanoate by ionic flocculation
(Elsevier, 2018-03-04)
Effects of Cu+2 and pH on the fitness of Ceriodaphnia dubia (Richard 1894) (Crustacea, Cladocera) in microcosm experiments
(2001)
An important disturbance of anthropogenic origin frequently occurring in freshwater ecosystems is a rise in the concentration of heavy metals in solution, among which copper stands out due to its known toxicity. However, ...
Study of the Hydrogen Evolution Reaction Using Ionic Liquid/Cobalt Porphyrin Systems as Electro and Photoelectrocatalysts
(MDPI, 2020)
In this work, the design and manufacture of graphite paste (Gr) electrodes is carried out, including N-octylpyridinium hexafluorophosphate (OPyPF6) ionic liquid (IL) as binder and modification with Co-octaethylporphyrin ...
Effect of soil copper content and ph on copper uptake of selected vegetables grown under controlled conditions
(SETAC, 2002)
A one-year greenhouse experiment was conducted to study the transfer of copper from contaminated agricultural soils to edible and nonedible structures of lettuce, tomato, and onion plants. Study soils Acre selected from ...
