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 5-45ΠC, pH between 4.0 and 6.5, and ionic strength 0.4 M. The equilibrium constants, stoichiometry, and pK a of the ligand a

Data and a consistent physical and mathematical model for the kinetic and equilibrium sorptive behavior of cesium with a particulate, nuclear-grade graphite (H-451) is given. The most important conclusions are: (1) The kinetics of absorption and desorption of cesium by H-451 graphite in particulate
The equilibrium and kinetics of the complexation of Co n by folic acid have been studied at 25 ~ the ionic strength being regulated with KNO 3 in the 5.6-7.3 pH range. Kinetic studies were performed using the stopped-flow method. Under our experimental conditions one process was observed; a reaction
The kinetics of oxidation of sulfanilic acid (p-aminobenzenesulfonic acid) by hexacyanoferrate(III) in alkaline medium was studied spectrophotometrically. The reaction showed first order kinetics in hexacyanoferrate(III) and alkali concentrations and an order of less than unity in sulfanilic acid co
