The concentration effect of ionic surfactants was investigated on the Briggs-Rauscher oscillatory reaction in a stirred batch reactor at 25 °C in both the absence and presence of an ionic surfactant. In the presence of the anionic surfactant, the in

The effect of cationic (CTAN), anionic (SDS) and nonionic surfactants (Brij-30 and Triton X-100) as well as of tert-butanol (t-BuOH) on the uncatalyzed bromate oscillator with phenol as substrate was investigated at 25 ± 0.1oC in non-stirred batch c

The response of an uncatalyzed bromate oscillator with phenol as substrate to the increasing concentrations of cationic (CTAN), anionic (SDS) and nonionic surfactants (Brij-30 and Triton X-100) was monitored at (25±0.1) °C under stirred batch condi

The oxidation of iodine with hydrogen peroxide was studied spectrophotometrically and potentiometrically. At low concentrations of HClO4, after induction period (IP), the iodine concentration decreases sigmoidally and IP decreases with decreasing sur

The reduction of ferriin ([Fe(phen)3]3+, phen = 1,10-phenanthroline) by malonic acid (MA) differs from the reduction of Ce(IV) or Mn(III) ions by MA in its autocatalytic character and in a pregnant influence of oxygen, which behaves obviously as a ca

The kinetics of the oxidation of iodine by hydrogen peroxide catalyzed by MoO2−4 ions with a ‘clock’ behaviour is described and the corresponding reaction scheme is proposed. The ‘clock’ behaviour is explained by the assumption that the oxi

A new transition metal oscillator based on the oxidation of Mn2+ ions by Fe(CN)3−6 ions in a CSTR has been found. As well as the oscillations of the absorbance of the Mn(IV) species, pH-oscillations have been observed. In the reduction of manganese
