III.Study of Complexation of Cu~(2+) Ions with Humic Acids in Sols:Study of Structure and Properties of Humic and Fulvic Acids.

摘要

Complexation of Cu~(2+) ions with humic acids (HA) in sols has been studied.Binding capacity of HA was determined on the basis of conductometric and potentiometric titrations.Equilibrium and rate constants of dissociation of HA and CuCl_2 and hydrolysis of cu~(2+) ions were detemined and used for description of mechanism ans kinetics of Complexation process in sols.Mathematical description of process kinetics was derived and discussed.
