AB  - In this study, we have attempted to reveal the physical or mechanistic features 
      of the sonochemical degradation of 2,4-dichlorophenol (2,4-DCP). The principal 
      physical phenomenon underlying sonochemical effects is radial motion of 
      cavitation bubbles and production of radicals from transient collapse of these 
      bubbles. We reveal some important physical facets of sonochemical degradation of 
      2,4-DCP by adopting dual approach of coupling experimental results with 
      simulations of radial motion of cavitation bubble. First, the location of the 
      degradation is predominantly the interfacial region between bubble and bulk 
      medium, and secondly, the extent of degradation is controlled by 
      conservation--and not the production--of oxidizing radicals that affects the 
      probability of radical-pollutant interaction.
