ABSTRACT
Reducing the amount of mercury in fluorescent lamps has been studied during recent years. The main problem relates to the consumption of mercury during lamp operation [1]. In this respect, the fixation of mercury to metallic Ba and Sr is an issue. Ba and Sr are formed during electrode operation. In this study, the results of an investigation of Ba and Sr amalgams are presented. These amalgams have been prepared via adsorption of mercury vapour by metallic Ba and Sr films at room temperature. The various amalgam phases have been characterised by thermal desorption analysis (TDA).
