The kinetics of complexation of Ni(II) by pterin was studied in aqueous solutions with a stopped-flow apparatus under conditions of pseudo-first order in the temperature range 5-45ЊC, pH between 4.0 and 6.5, and ionic strength 0.4 M. The equilibrium constants, stoichiometry, and pK a of the ligand a
The ratio of citric acid to D-isocitric acid can be used to distinguish authentic and adulterated fruit juices. To separate DL-isocitric acid enantiomers, we used ligand exchange CE. D-Quinic acid was used as a chiral selector ligand and Mn(II), Fe(III), Co(II), Ni(II), Cu(II), and Zn(II) ions were
The kinetics of complexation of nickel(II) with some penicillins and related compounds show that the zwitterionic form of the ligand has very low reactivity compared to the anionic form. The resolved rate constants are interpreted in terms of binding to the ring nitrogen and carboxyl group and not t
