The kinetics study of the reduction of Fast Green dye with cetylpyridinum chloride as cationic surfactant

Abstract

The kinetics of the reaction of Fast Green dye (FG) with cetylpyridinum chloride was studied in alkaline medium by UV-Visible spectrophotometer. Reduction of Fast Green dye was carried out by varying the fast green dye concentration, cetylpyridinum chloride concentration and concentration of sodium hydroxide. In the present study the reduction of dye was carried out in order to reduce the color content. The interaction of dye was carried out with reducing analyte (cetylpyridinum chloride). The rate of the reaction was determined by varying the above parameters at different temperatures. It was observed that the reduction followed pseudo first-order kinetics with respect to dye, surfactant, OH^- ion concentration according to the following reaction pathway.Fig.1

The mechanism for the photo bleaching of the dye has beenproposed and well confirmed by the data simulation procedure. The activation parameters of the reaction like entropy of activation (ΔBoldItalic) and free energy of activation (ΔBoldItalic) showed the extremely solvated states of transient complex which was less disorderly arranged than the oxidized form of dye, whereas BoldItalic_BoldItalic values reflects a high amount of energy required for the reduction of dye with cetylpyridinum chloride.
