The important role of 499-40-1

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 499-40-1 is helpful to your research., Electric Literature of 499-40-1

Metal-binding affinity of a series of bis(2-pyridylalkyl) amines immobilized on silica

Four potentially tridentate bis(2-pyridylalkyl)amines, differing in the number of methylene groups in the alkyl chain, have been coupled to the epoxy-containing bifunctional spacer (3-glycidoxypropyl)trimethoxysilane (GLYMO) and subsequently grafted onto silica. These ion exchangers were characterized by solid-state CP-MAS 13C-NMR and elemental analyses. The obtained ligand concentrations varied from 0.29-0.63 mmol/g ion exchanger. With the only exception of Alfa-GLYMO-bis(2-pyridyl)amine, which showed a very low capacity for any of the metal ions tested, these ion-exchange materials selectively absorbed Cu2+, with a maximum capacity of 0.22-0.59 mmol/g ion exchanger at pH 5.6, from aqueous solutions containing a mixture of the divalent metal ions Cu2+, Ni2+, Co2+, Cd2+ and Zn2+. The metal-uptake capacities and distribution coefficients established at different pH, correlate with the length of the alkyl bridge in the chelating ligand. The longer the alkyl spacer the lower the capacity and the metal-ligand complex stability at lower pH. The use of strong chelating tridentate N-donor ligands greatly increases the ligand occupation by metal ions. The Cu2+ uptake varies strongly with pH in the case of Alfa-GLYMO-bis[2-(2-pyridyl) ethyl]amine.
