A microanalyzer prototype for copper(II) ion monitoring in mining industrial processes is presented. The microanalyzer is designed as an assembly of different modules, each module being responsible for a unit operation. In order to optimize the industrial processes, the microanalyzer can automate all sample management, signal processing, and mathematical calculations and wirelessly transfer data to a control room. The determination of copper(II) ion is done using a colorimetric reaction and the microanalyser performs autocalibration by in situ dilution of a stock solution, matching the higher

Abstract Under alkaline conditions, copper-nickel alloys are covered by passive oxide films containing Cu and Ni oxides. In chloride ion containing environments, they are therefore susceptible to localized corrosion. In this paper, the susceptibility of selected Cu-Ni alloys (UNS C70600, UNS C71500 and UNS N04400) to localized corrosion was investigated by measuring the crevice stabilization and repassivation potentials (Ecrev and Ercrev, respectively) in alkaline sodium chloride solutions. Correlations between environmental variables, such as chloride ion concentration, pH and temperature and

Abstract:
A model has been developed to predict the corrosion behaviour of copper nuclear waste containers in a Canadian disposal vault. The model is based on a finite-difference solution of a series of mass-balance equations that describe the effects of mass transport and various chemical and electrochemical reactions between the container material and the surrounding environment. Each of these reactions is discussed briefly. The corrosion behaviour of the containers is expected to change over time as the environmental conditions within the disposal vault evolve. For copper, the most important environm

Abstract:
Abstract The data on scale inhibition mechanisms are critically analyzed with the emphasis on the published data disparity and controversy. On the grounds of three independent approaches it is demonstrated that foreign background “nanodust” particles have a dramatic impact on antiscalant efficacy. These approaches include: (i) a direct nanoparticle counter application in stock solutions; (ii) a novel DLS special technique, based on the standard nanoparticles injection into the supersaturated inorganic salt solution during the induction period; and (iii) an application of fluorescent-tagged ant

Abstract:
In this research, a series of copper complexes containing polypyridyl ligands were designed to study the influence from ligands, nuclearity, solvents and secondary coordination on reactivity toward small-molecule activation. This structure-reactivity relationship was used in investigation for oxygen reduction reactions (ORR), and applied in detection of ascorbic acid (AsH₂). Firstly, copper (II) complexes containing polypyridyl derivatives ligands (i.e., Cu(dpa), Cu(adpa) and Cu₂ (addpa)) were synthesized and fully characterized by elemental analysis, mass spectrometry and X-ray crystallograph
