MICROSECOND PULSE RADIOLYSIS OF BENZOPHENONE TRIBUTYL PHOSPHATE SYSTEM

摘要

It was found that an absorption peak with λ_(max) = 560 nm in the pulse radiolysis of benzophe-none-TBP system, which was assigned to the ketyl radical of benzophenone. The yields for the ketyl radical on benzophenone concentrations have been measured, which were well fitted with the Stern-Volmer equation. Analysis of the data, combining with the previous study, an energy transfer mechanism was proposed, the obtained G_(TBP~*)~0, was 2.54 and the ratio of rate constants for TBP~* dissociation to energy transfer was 840.
