Influence of estrogens on copper indicators: In vivo and in vitro studies
(2010)
Classic copper indicators are not sensitive and specific for detecting excess copper exposure when this is higher than customary but not markedly elevated. Serum copper and ceruloplasmin (Cp) are the most commonly used ...
Searching for specific responses to copper exposure: An in vitro copper challenge in peripheral mononuclear cells
(2011)
Acute and chronic cellular responses to changes in copper availability are not clear when these changes are mild to moderate, as what often occur in human daily life. The aims of the study were to develop an in vitro copper ...
Sulfate removal rate and metal recovery as settling precipitates in bioreactors: Influence of electron donors
(Elsevier B.V., 2021-02-05)
Four down-flow structured bed bioreactors were operated targeting biological sulfate-reduction and metal recovery. Three different electron donors were tested: glycerol (R1), lactate (R2), sucrose (R3), and a blend of the ...
Enhancement of copper toxicity in cultures of Dictyosphaerium pulchellum (Chlorophyceae) by mucilage removal
(Schweizerbart Science Publishers, 2005-04)
Extracellular mucilage from cells of Dictyosphaerium pulchellum Wood 1872 was removed by controlled ultrasonication. Batches of exponentially growing cells, with and without mucilaginous capsules, were incubated during 48 ...
Copper Electrodeposition Kinetics Measured by Alternating Current Voltammetry and the Role of Ferrous Species
(Electrochemical Soc, 2016)
Impurities and additives play a key role in copper electrodeposition, in particular in upstream processes such as electrowinning or electrorefining. One common impurity is iron, mostly present as iron species Fe(II) in ...
Removal of copper in a sulfate reducing bioreactor with a limestone pre-column system

Synthesis and spectroscopic characterization of new metal(II) complexes with methionine sulfoxide
(2004-09-20)
Methionine sulfoxide complexes of iron(II) and copper(II) were synthesized and characterized by chemical and spectroscopic techniques. Elemental and atomic absorption analyses fit the compositions K2[Fe(metSO) 2]SO4 · H2O ...

Study of chitosans interaction with Cu(II) from the corresponding sulfate and chloride salts
(Springer, 2015-08-01)
The interaction of copper ions with chitosan and three synthesized derivatives with different chelating centers, N-benzylidene chitosan, N-benzyl chitosan and poly-N-(4-(4-R-methoxyphenyl) diazenyl)benzyl-chitosan using ...
