| Abstract: | A chemical-physical method for treatment of aniline containing waste water was developed. At the chemical stage aniline is polymerized by Fenton's reagent. Thus insoluble polyaniline precipitates. The best reaction conditions are: pH-value of 2–3, stepwise dosing of 60 mL H2O2 (30%) and 12 mL saturated FeSO4-solution per litre waste water. The molar ratio Fe(II): H2O2 amounts to 0.3:10. The concentration of aniline is reduced by this chemical treatment from about 20 g/L to 30–40 mg/L. By adsorption at activated charcoal the concentration of aniline can be reduced further to 0.2 mg/L. The resulting sludge can easily be dewatered in a chamber filter press. |
