TI  - Degradation of azo dye Acid black 1 using low concentration iron of Fenton 
      process facilitated by ultrasonic irradiation.
PG  - 761-6
AB  - A combination of ultrasonic and low concentration iron (<3 mgL(-1)) of Fenton 
      process (US/Fenton) has been used to treat wastewater containing Acid black 1 
      (AB1). The results show that the oxidation power of low concentration iron of 
      Fenton could be significantly enhanced by ultrasonic irradiation. The degradation 
      of AB1 in aqueous solution by US/Fenton can receive better results compared with 
      either Fenton oxidation or ultrasonic alone. Many operational parameters, such as 
      ultrasonic power density, the pH value, the Fe(2+) dosage, the H(2)O(2) dosage, 
      AB1 concentration and the temperature, affecting the degradation efficiency were 
      investigated. Also, the effects of various inorganic anions (such as Cl(-), 
      NO(3)(-), CO(3)(2-), etc.) on the oxidation efficiency of US/Fenton were studied. 
      Under the given test conditions, 98.83% degradation efficiency was achieved after 
      30 min reaction by US/Fenton. The effect of various inorganic anions was in the 
      following decreasing order: 
      SO(3)(2-)>CH(3)COO(-)>Cl(-)>CO(3)(2-)>HCO(3)(-)>SO(4)(2-)>NO(3)(-). The results 
      show that the US/Fenton can be an effective technology for the treatment of 
      organic dyes in wastewater.
