General description

Ferroin serves as an indicator of oxidation reduction reactions in titrimetric analysis. Ferroin is the complex of 1,10-phenanthroline and Fe(II). It is also used as a catalyst for Belousov−Zhabotinsky reaction.

Application

Ferroin indicator solution is suitable for wastewater analysis of the parameters like chemical oxygen demand (COD) and total organic carbon (TOC).

We describe an improved Taylor dispersion method for four-component systems, which we apply to measure the main- and cross-diffusion coefficients in an Aerosol OT water-in-oil microemulsion loaded with one of the reactants of the Belousov-Zhabotinsky (BZ) reaction, water(1)/AOT(2)/R(3)/octane(4) system, where

In the present mechanistic schemes of the ferroin-catalyzed oscillatory Belousov-Zhabotinsky (BZ) reaction the oxidation of the organic substrates (bromomalonic or malonic acid) by ferriin (the oxidized form of the catalyst) plays an important role. As the organic products of these
