Degradation of 2,4-D by Nano-scale Fe_3O_4

FANG Guo-dong,SI You-bin(School of Resource and Environment,Anhui Agricultural University,Hefei 230036,China)  
Nano-scale Fe3O4 was used to degrade 2,4-D in aqueous solution.Results showed that initial concentration of 2,4-D,pH and nano-scale Fe3O4 dosage were important factors for the degradation of 2,4-D.It was found that the decomposition efficiency of 2,4-D by nano-scale Fe3O4 was higher than micro-scale Fe3O4,and the concentration of chlorine ion increased with degradation of 2,4-D.It suggested that the degradation mechanism of 2,4-D was reductive dechlorination.Degradation of 2,4-D increased with increase of initial concentration of 2,4-D of 0~10mg/L and nano-scale Fe3O4 dosage of 0~300mg/L.40% of 2,4-D could be degraded after 48h with 300mg.L-1 nano-scale Fe3O4,at pH of 3 and initial concentration of 2,4-D 10mg/L.
