Comparative study of binding strengths of heavy metals with humic acid [PDF]
Hemijska Industrija, 2013 The complexation of humic acid with certain heavy metal ions (Co(II), Ni(II), Cu(II), Zn(II) and Pb(II)) was investigated. The stability constants of humate complexes were determined by method which is based on distribution of metal ions between

On brane stabilization and the cosmological constant [PDF]
Physics Letters B, 2001 We address the problem of the cosmological constant within the Randall-Sundrum scenario with a brane stabilization mechanism. We consider brane tensions of general form. We examine the conditions under which a small change of the positive tension of the first brane can be absorbed in a small modification of the two-brane configuration, instead of ...

Stability of Poincar{é} constant
, 2021 We study stability of the sharp Poincar{é} constant of the invariant probability measure of a reversible diffusion process satisfying some natural conditions. The proof is based on the spectral interpretation of Poincar{é} inequalities and Stein's method.

Study on Coordination Chemistry of U(Ⅵ) with N,N-dimethyl-6-amide-pyridine-2-carboxylic Acid
Yuanzineng kexue jishu, 2023 The very strong complexing capacity of pyridine-2,6-dicarboxylic acid (DPA) with lanthanides/actinides of different oxidation states in aqueous solutions makes it a selective complexing agent or stripping agent in various separation systems. Besides DPA,

Determination of the side-reaction coefficient of desferrioxamine B in trace-metal-free seawater
Frontiers in Marine Science, 2016 Electrochemical techniques like adsorptive cathodic stripping voltammetry with competitive ligand equilibration (ACSV-CLE) can determine total concentrations of marine organic ligands and their conditional binding constants for specific metals, but ...
