Disappearance of basic yellow 28 from aqueous solution by Fenton's reagent

The disappearance of basic yellow 28 from aqueous solution has been investigated using fenton's reagent (fe2+ and h2o2). the effects of different reaction parameters such as initial ph,the initial hydrogen peroxide concentration ([h2o2]0),the initial ferrous concentration ([fe2+]0),the initial basic yellow 28 concentration ([dye]0) and the temperature on the disappearance of basic yellow 28 have been assessed. the optimal reacting conditions were experimentally determined and it was found to be initial ph = 3.00,[h2o2]0 = 0.20 mm,[fe2+]0 = 0.14 mm for [dye]0 = 13 μm at temperature = 25°c. under optimal conditions,90 % disappearance efficiency of dye from aqueous solution was achieved after 2 min of reaction.
