| Abstract: | An analytical method for simultaneous determination of molybdenum and rhenium by reversed - phase high performance liquid chromatography with diethyldithiocarbamate as the pre - column derivative reagent has been established. Two metal ions were separated on a C18 reversed - phase column （4.6 × 150 mm） with methanol： water = 15：85 as the mobile phase and was detected at 254 nm. The detection limit for molybdenum and rhenium are 2.1 ng/mL and 1.3 ng/mL respectively. The linearity range and relation can meet the requirement of quantitative analysis for molybdenum and rhenium. |
