Article's abstract:

In this study, the oxidation of dye from colored wastewater by H2O2/ MWCNT’s multi walls carbon nano tubes solution assisted with UV radiation was investigated. Disperse Blue 56 DB 56 was used as a model dye. Adsorption behavior of DB56 from aqueous solution onto MWCNT’s was investigated under various conditions such as initial pH value, dye concentration, H2O2 and MWCNT’s dosage. Maximum adsorption capacity for DB 56, at pH 7.0, 5.0 and 3.0 was found to be 0.53, 0.56 and 0.97 mmol/g, respectively. Obtained result of isotherm displayed that the linear correlation coefficients and standard deviations of Nernest and Freundlich isotherms were specified and the results revealed that Freundlich isotherm fitted the experimental results better than Nernest. The adsorption kinetics was more precisely denoted by a pseudo second-order model revealed by regression grades. Furthermore, results displayed that the UV/H2O2/MWCNTs process could be used as eco-friendly method to degrade dyes from colored wastewater.
