Endotoxin inactivation in water by using medium-pressure UV lamps.
Deionized water was spiked with various concentrations of endotoxin and exposed to UV irradiation from medium-pressure UV lamps to assess endotoxin inactivation. It was found that endotoxin inactivation was proportional to the UV dose under the conditions examined. The inactivation rate was determined to be approximately 0.55 endotoxin unit/ml per mJ/cm(2) of irradiation delivered.
