Abstract: A new color reaction of Sc with chlorophosphonago-pB (CPA-pB) has been studied. By normal operation of spectrophotometry, the molar absorptivity is 7.0 x 10^-4 L mol-1 cm-1, and Beer's law is obeyed in the range of 7-18 µg Sc2O3/25 ml at 740 nm. By flow injection analysis spectrophotometric method associated with micro-computer, the Linear range is expanded to 5-45 µg Sc2O3/25 ml. The FIA is rapid, automatic, good accuracy and high repeatability, This method can be used to determine the Sc in the rock.
