Abstract

The discharge of wastewater containing reactive dyes into water sources leads to health hazards. Colors can adversely affect the natural environment due largely to some qualities like carcinogenicity, being mutagenic, toxicity, and Coloration of water. Environmental degradation can be attributed to the destruction of living organisms and the increased biological oxygen demand (BOD). The aim of this study was to evaluate the removal of Color:#ff0078">Reactive Blue 19 dye using the Fenton process from aqueous solution. This research was an experimental study, in which the effectiveness of Fenton in Color removal was investigated. The factors influencing this process were: pH, Color concentration, the ratio of Fenton reagent (H2O2/Fe2+), and contact time. Finally, after determining the optimum concentration of Color, pH, the ratio of Fenton reagent, and contact time, the residual adsorption rates in the samples were measured using direct photometry by spectrophotometer in a wavelength of 594 nm. The results showed that the highest removal efficiency was obtained under the conditions of pH =3, the Color concentration of 2 mg/L, the ratio of Fenton reagent = 1: 5, and the contact time equal to 10 minutes. The Fenton process is able to remove the Color:#ff0078">Reactive Blue 19 under different concentrations. This process achieved the best removal efficiency in acidic pH.
