[Rapid method for preparing Ehrlich hematoxylin]

The new method consists of electrolysis for 48 hrs of haematoxylin template solution prepared by the standard method. The dye, after electrolysis, acquires the appearance and properties of hematoxylin prepared by the method of maturation at sunlight during several months. Spectral analysis of the dye and theoretical basis of the electrolytical acceleration of the dye maturation are presented.
