and Objective: Mercaptan is used to add odor to natural gas. The current method utilized for deodorizing empty barrels by sodium hypochlorite has been carried out through chemical oxidation and reported with some problems. In this regard, the current study investigated the changes in the initial concentration parameters of sodium ferrate nanoparticles, initial temperature, and initial pH in the removal efficiency of the odorant. Materials and Methods: To evaluate sodium ferrate nanoparticles in

Results: The obtained results of the present study showed that by increasing the sodium ferrate concentrations, the removal efficiency of the odorant increased through decreasing the initial temperature and pH. Conclusion: The use of sodium ferrate nanoparticles was investigated in this study due to the reduction of the oxidation time and number of used chemicals, ease of operation by this material, safe operation, odorlessness, nontoxicity, and high performance.
