Synergistic Degradation of Acid Scarlet Dyeing Wastewater by the Ultrasound/Fenton Method

Abstract:

Degradation of simulated acid scarlet (GR) wastewater by ultrasonic technology , Fenton reagentoxidation , and a combination of the two processes was studied. It was found that extent of degradation by ultrasonic technology or Fenton reagent oxidation alone was poor , with values of 4 % and 40 % respectively. The extent of degradation was significantly enhanced when the two processes were combined , with a value of up to 90 % , which shows that these two processes have a good synergistic effect and can shorten the reaction time.Also discussed the initial concentration, initial pH, Fe²⁺ and H₂O₂ dosage and other factors on the degradation of acid scarlet. The results show that the degradation rate of pH significant effect on the low pH is conducive to degradation. Degradation rate with the dosage of H₂O₂ and FeSO₄ temperature increased, but when acid scarlet with H₂O₂ and Fe²⁺ the mass ratio of 100:15:41, the degradation rate reached 96.6%.
