Stability of Bromate Species Immobilized on Alumina Microcolumns

2 Stability of Bromate Species Immobilized on Alumina Microcolumns 

The previous section addressed the effect of water matrix on bromate stability. This section investigates the possibility of developing an alternative approach to sampling of bromate species in waters by employing columns of a selective packing material. This study was based on the development of an FI system with aluminamicrocolumns
