A New Electrode System With Efficient Mixing of Electrolyte

In the last decade, many authors have emphasized the exceptional possibilities of polarography and the related advanced techniques for the determination and physico-chemical characterization of dissolved trace metals in natural aquatic systems.In addition to the quantitative aspects, it is also possible to characterize the physicochemical state of ionic species in natural and polluted wate rs. This is oL particular importance for the inve stigation of basic biogeochemical processes. These methods could be used for the elucidation of mechanisms and pathways in the biogeochemical cycles of a particular metal in natural and polluted aquatic systems
