NOVELTY - Manufacturing persulfate-ferromanganese-graphene oxide particles involves mixing persulfate and EDCs i.e. endocrine disrupting compounds-contaminated water, and then stirring the obtained mixture at room temperature under 160-250 revolutions per minute for 20-25 minutes. The persulfate is selected from potassium persulfate, ammonium persulfate, sodium persulfate or calcium sulfate. The obtained EDCs-contaminated mixture is mixed with perchloric acid, followed by addition of sodium hydroxide solution to adjust pH between 6.5-7.5. USE - Method for manufacturing persulfate-ferromanganese-graphene oxide particles used for removing residual amount of secreted endocrine disruptors from waste water (claimed). ADVANTAGE - The manufactured persulfate-ferromanganese-graphene oxide particles are capable of removing 85-95% of residual amount of secreted endocrine disruptors from waste water, in an efficient manner. DETAILED DESCRIPTION - Manufacturing persulfate-ferromanganese-graphene oxide particles involves mixing persulfate and EDCs i.e. endocrine disrupting compounds-contaminated water, and then stirring the obtained mixture at room temperature under 160-250 revolutions per minute for 20-25 minutes. The persulfate is selected from potassium persulfate, ammonium persulfate, sodium persulfate or calcium sulfate. The obtained EDCs-contaminated mixture is mixed with perchloric acid, followed by addition of sodium hydroxide solution to adjust pH between 6.5-7.5. Ferromanganese deoxidizer and graphene oxide dispersion are mixed together and then transferred to 97-99 wt.% ethylene glycol solution. The obtained mixture is processed ultrasonically for 3-4 hours to obtain dispersion. The prepared dispersion is formulated with a solution of sodium citrate and ethylene glycol, and then heated at 60-75 degrees C for 20-45 minutes to obtain sodium citrate-ethylene glycol solution. Sodium citrate, ethylene glycol, added iron(III) chloride hexahydrate, urea and manganese(II) chloride hydrate. The mixture is stirred at room temperature on a magnetic stirrer at 100-250 revolutions per minute for 2-4 hours to obtain ferromanganese-sodium citrate-ethylene glycol complex solution. the prepared ferromanganese-sodium citrate-ethylene glycol complex solution is added to Teflon (RTM: Polytetrafluoroethylene-based product)-lined stainless steel for autoclaving at 200-230 degrees C for 12-48 hours, and then cooled at room temperature to obtain a black suspension. The obtained black suspended is centrifuged in a centrifuge at a speed of 6500-8000 revolutions per minute for 10-30 minutes to obtain precipitated material. Methanol and deionized water are added to the obtained precipitated material, where the mixture is centrifuged to obtain persulfate-ferromanganese-graphene oxide particles, which are then freeze-dried for 24-48 hours. The obtained persulfate-ferromanganese-graphene oxide particles are dried at 50-75 degrees C for 12-48 hours to obtain the finished product.
