natural water monitoringThe catalytic effect of copper(II) on the chemiluminescence reaction of luminol oxidation in the presence of some modeling organic substances of natural waters, i.e., EDTA and citric and glutamic acids, is studied. A comparison of the data obtained with the calculated ...

Copper (Cu) is a widely studied trace metal due to its importance for various biological functions1. It also plays a role as a toxicant when present in high concentrations of the unbound ion, Cu2+ 2,3,4. The cycling of dissolved Cu (Cu) in the oceans, estuaries and rivers has been...
We have separated two groups of copper-complexing ligands (the weak and strong ligands) from streamwaters in the Lake Biwa watershed by modified immobilized metal ion affinity chromatography (IMAC). The weak ligands were about 0.54-1.21% of the total dissolved organic matter (DOM), as determined...
The presented data clarifies that the metals exhibited clear differences in their distribution between particulate and dissolved forms. The concentrations of particulate metals viz: Zn, Pb, Cd, Fe and Mn were high as compared to the dissolved form. Dissolved copper showed the highest percentage of ...
What is distillation and why is tap water a conductor of electricity and distilled water is not? What mechanisms occur when K+ ions are added so there is a high concentration of extracellular K+ ions? If your hand is in water, why would copper (ion in water...

Dissolved organic matter(DOM) is the dominant form of organic matter in the water column of inland waters. It consists of dissolved molecules as well as aggregates of molecules. These aggregates can be viewed as colloids, i.e., particles small enough to remain in suspension rather than sinkin...
