Abstract :
Background: Recently, there has been a great concern about
the consumption of dyes because of their toxicity, mutagenicity,
carcinogenicity, and persistence in the aquatic environment.
Reactive dyes are widely used in textile industry. Advanced
oxidation processes are one of the cost-effective methods for
the removal of these dyes. The main aims of this study were
determining the feasibility of using Fenton process in removing
Reactive Red 198 (RR-198) dye from aqueous solution and
determining the optimal conditions.
Methods: This is a cross-sectional study conducted at a
laboratory scale. A total of 69 samples were considered and the
effect of pH, Fe (II) concentration, H2O2 concentration, initial
dye concentration and reaction time were investigated.
Results: According to the results, a maximum removal efficiency
of 92% was obtained at pH of 3 and the reaction time of 90 min;
also, the concentration of Fe (II), H2O2, initial dye concentration
were 100 mg/L, 50 mg/L, and 100 mg/L, respectively. The results
revealed that by increasing the concentration of Fe (II), H2O2 and
initial dye, the removal efficiency was increased.
Conclusions: The results showed that Fenton process could be
used as a cost-effective method for removing RR-198 dye from
textile wastewater efficiently.
