Abstract
New spectrophotometer was designed for the simultaneous assay of copper and iron using flow injection analysis and moreover, new 50 mm light path cells were equipped in the spectrophotometer to enhance the sensitivity. Both copper and iron at 2–10 ppb level were determined simultaneously and rapidly using water soluble reagent, 5-Br-PSAA. Determination limits were 1 ppb for copper and 1 ppb for iron. Relative standard deviations were about 1%.
