Photochemical surface decontamination

Photochemical Surface Decontamination Application to a Polychlorinated Biphenyl Spill Site... 

The field test consisted of decontaminating the PCB-tainted concrete surface. Before and after 21 hr of photochemical treatment a 1.2 m area was sampled extensively (n = 8) to quantify PCB residues. Treated and control samples were located on alternate positions of a grid to minimize sampling error. 

Photochemical treatments hold promise for on-site decontamination of hazardous substances on various surfaces including building walls and floors, machinery and electrical equipment (e.g., transformer cases). Further applications include cleaning equipment used in remedial activities at contaminated sites and in...
