Abstract
New spectrophotometer was designed for the simultaneous assay of copper and iron using flow injection analysis and moreover, new 50 mm light path cell s were equipped in the spectrophotometer to enhance the sensitivity. Both c opper and iron at 2-10 ppb level were determined simultaneously and rapidly using water soluble reagent, 5-Br-PSAA. Determination limits were 1 ppb fo r copper and 1 ppb for iron. Relative standard deviations were about 1%. (C ) 2000 Elsevier Science B.V. All rights reserved.
