The radiation in the visible and ultraviolet regions from submerged, transient electrical arcs was measured with a K(3)Fe(C(2)O(4))(3) chemical actinometer and was compared to the bactericidal effect obtained with the same electrical arrangements. Photon production and bactericidal effect were obtained at lower voltages with a smaller electrode separation than with a wider one. At higher voltages, both increased with wider electrode separations. The voltages at maximal photon production efficiency coincided with those of maximal bactericidal efficiency. However, the same photon radiation produced by different electrical arrangements did not always yield the same bactericidal effect in the small discharge vessel usually employed. In a larger discharge vessel, the bactericidal effect was closely correlated with the photon production. The efficiency of photon production by transient arcs was smaller than that of germicidal mercury lamps, particularly with respect to wavelengths of great bactericidal activity. The mechanisms of inactivation and their use for practical disinfection purposes are discussed.
使用K(3)Fe(C(2)O(4))(3)化学感光计测量了水下瞬态电弧在可见光和紫外线区域的辐射，并将其与相同电气装置产生的杀菌效果进行了比较。与较宽电极间距相比，在较低电压和较小电极间距下可获得光子产生和杀菌效果。在较高电压下，两者均随电极间距变宽而增加。最大光子产生效率时的电压与最大杀菌效率时的电压一致。然而，在通常使用的小型放电容器中，不同电气装置产生的相同光子辐射并不总是产生相同的杀菌效果。在较大的放电容器中，杀菌效果与光子产生密切相关。瞬态电弧产生光子的效率低于杀菌汞灯，特别是在具有高杀菌活性的波长方面。讨论了灭活机制及其在实际消毒中的应用。
