Description
Summary:Chemical oxidation is an effective method for treating wastewater that contains dyes. Ferrate is known as the strongest and environmentally friendly oxidizer in aqueous media. This study aims to degrade remazol black B dyes using ferrate synthesized by the wet chemical method from Ferrous ion of FeSO 4 .7H 2 O. This research studies the optimum conditions of degradation including pH, molar ratio and optimum time, degradation kinetics and the comparison of the effectiveness in degrading Remazol Black B dyes among ferrate to permanganate, peroxide and dichromate. The results show that ferrate can oxidize remazol black B effectively at an optimum pH 8, with a molar ratio of ferrates:dyes of 5:1 and the optimum time of degradation of 120 minutes, with the degradation percentage reaches up to 95%. The degradation kinetics of dyes follows first-order kinetics, and ferrate has the highest degradation effectiveness compared to permanganate, peroxide and dichromate.
