Copper in infant nutrition: Safety of World Health Organization provisional guideline value for copper content of drinking water
(1998)
Background: Copper is an essential nutrient for humans. Recently, a limit of 31.48 μmol/l (2 mg/l) was proposed by the World Health Organization as the provisional guideline value for copper content of drinking water. The ...
Simultaneous determination of copper and iron by solvent extraction and first derivative spectrophotometry
(1995)
A simple, sensitive and selective first derivative spectrophotometric method has been developed for the determination of copper and iron in mixtures. The method is based on the recovery of the analytes, by liquid-liquid ...
Relationship between copper doses in parenteral nutrition mixtures, serum copper, erythrocyte copper levels, ceruloplasmin and C-reactive protein, in critically ill patients
(Universidad de Belgrano - Facultad de Ciencias Exactas y Naturales - Proyectos de Investigación, 2014)
Background and aims: There is no consensus on the recommended amounts of copper to be administered
to critically ill patients on parenteral nutrition, as requirements are variable and very difficult to
determine in ...
Copper determination in ethanol fuel samples by anodic stripping voltammetry at a gold microelectrode
(Springer Wien, 2009-01-01)
A linear sweep anodic stripping voltammetric method was developed for copper determination in commercial ethanol fuel samples by using a gold microelectrode. Under the optimized conditions, a linear range from 0.05 to 1.0 ...

Levels of copper in Nile tilapia from Brazil
(Taylor & Francis Ltd, 2011-01-01)
The purpose of this work was to determine the concentration of copper in samples of farmed Nile tilapia (Oreochromis niloticus L.) fillets purchased in the city of Botucatu (São Paulo, Brazil) and in fillet and liver samples ...
Impact of copper ligand mutations on a cupredoxin with a green copper center
(Elsevier Science, 2017-05)
Mononuclear cupredoxins contain a type 1 copper center with a trigonal or tetragonal geometry usually maintained by four ligands, a cystein, two histidines and a methionine. The recent discovery of new members of this ...
Dataset of copper pipes corrosion after exposure to chlorine
(2018)
This article presents data on corrosion and dissolved copper in copper tubes that transport drinking water in domiciles of the Azogues city, Ecuador. Corrosion tests were performed using copper coupons exposed to water ...
