ABSTRACT
A catalytic spectrophotometric method for determination of trace molybdenum by flow injection analysis has been established, based on the catalytic oxidation of potassium iodide by hydrogen peroxide in the presence of molybedenum (VI) and the iodine produced is coloured with starch. The linear range and detection limit for molybdenum (VI) were 0 to 0.4 ppm and 3.2 ppb. The method has been successfully applied to determine molybdenum in the grain, soil and hair.
