Application of Fenton reagent and adsorption as advanced treatment processes for removal of Maxilon Red GRL

In this paper, the removal of Maxilon Red GRL by adsorption onto raw soil sample known as Niğde (Bor) grape molasses soil and Fe+2/H2O2 reagent as advanced treatment processes were investigated. The effects of various experimental parameters such as initial Fe+2 and H2O2 concentrations, pH, temperature, contact time, initial adsorbent dose, and initial dye concentration on adsorption and Fenton process efficiencies were studied in a batch reactor. The adsorption experimental data were modeled by Langmuir and Freundlich isotherm models. The data fitted well with the Langmuir isotherm (R2>0.99). The optimum conditions had been determined and found that efficiency of decolorization obtained after 20 min of reaction, was about 99.4% for Fenton process.
