Release of weak and strong copper-complexing agents by algae1
By means of potentiometric titrations, the copper-complcxing properties of organic compounds released by 21 algal species are characterized. Most eucaryotic species relcascd measurablc amounts (lo-” M) of copper-complexing agents that could be modeled as weak organic acids with log{*&.,,,} = 0.5. Of seven blue-green algal species studied, four produced about 5 x lo+ M concentrations of strong c...
متن کاملStrong Topological Regularity and Weak Regularity of Banach Algebras
In this article we study two different generalizations of von Neumann regularity, namely strong topological regularity and weak regularity, in the Banach algebra context. We show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. Then we consider strong topological regularity of certain concrete algebras. Moreover we obtain ...
متن کاملKinetics of copper(II) uptake by apoazurin in complexing media.
We have studied the kinetics of copper uptake by apoazurin in imidazole and 1-methylimidazole buffers in the pH range of 7-9 with mu = 0.5 M and copper(II) in large excess. The reaction has been monitored by measuring the visible absorbance and circular dichroism as a function of time. The uptake occurs in a stepwise fashion, and at least two intermediates are implicated. Overall, the rate of u...
متن کاملPhotodegradation of strong copper-complexing ligands in organic-rich estuarine waters
Exposure to solar radiation substantially decreased the strong copper-complexing capacity of samples collected from the organic-rich Cape Fear estuary, North Carolina. Samples exposed to natural sunlight for 1–2 d experienced a loss of strong Cu ligand (modeled at fixed K9CuL 5 1013.5) ranging from 15–33%, and .90% using long-term exposures under controlled conditions with a Xe arc solar simula...
