The chemiluminescence (CL) reaction between lucigenin (Lu) and molybdenum (III) produced by a Jones rcductor was investigated using a flow injection system. On the basis of this, a novel method for the determination of trace amount of molybdenum has been established. The emission intensity was linear with molybdenum concentration in the range of 0.1-1000ng/mL; the detection limit was 0.02 ng/mL molybdenum, the relative standard deviation was less than 2% for the determination of 0.1 ng/mL molybdenum (n=11). The method has been applied successfully to the analysis of trace molybdenum in water and steel samples.
