TI  - Degradation of chlorophenols in aqueous media using UV XeBr excilamp in a 
      flow-through reactor.
PG  - 1124-7
AB  - 2-Chlorophenol (2-CP), 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) at 
      initial concentrations of 10, 20, 50 and 100mg l(-1) were degraded in aqueous 
      media by direct UV photolysis using dielectric barrier discharge XeBr( *) 
      excilamp (283nm) in a flow-through photoreactor. The pseudo-first order rate 
      constants were highest and half-life times were lowest for 4-CP. The rates of 
      photolysis under the experimental conditions increased in the order: 
      2-CP<2,4-DCP<4-CP. The intermediates of photolysis were identified by GC-MS and 
      HPLC. The evolution of hydroquinone and p-benzoquinone as major intermediates of 
      4-CP photolysis was monitored.
