Abstract
Photochemical reactions are carried out by passing the fluid to be irradiated through a plurality of capillaries, each of which is surrounded by an actinic-radiation emitting plasma; the capillaries being transparent to the radiation. By banding the capillaries with a radiation-opaque material, the fluid being treated can repeatedly be subjected to brief periods of irradiation, alternating with periods of non-irradiation, during each pass through the capillaries.
