Study the Effect of Magnetized Water on Some of the Chemical Parameters for EBT Complexes with Some of M2+ Ions

摘要

In this paper, the effect of magnetized water on the stability constant Kst, oscillation strength f, molar extinction coefficient epsilon(max )and Gibbs free energy Delta G for complexes was investigated. Complexes of Eriochrome black T (EBT) as a ligand with Ca2+, Mn2+, and Zn2+ ions were prepared for this purpos. The stability constant values of the complexes found to be decreased by using magnetic water in their preparation except for EBT-Ca complex. Both Ca2+ and Mn2+ ions showed deviation from Irving-Williams order. The oscillation strength shows the type of spectrum is absorption spectrum for all complexes and in both in magnetized and non-magnetized water. epsilon(max )found to be increased by using magnetized water over than non-magnetized water. The stability constants for the complexes calculate analytically by applying jobs method and Yoe and Jones method.
