• 中文摘要： Determination of trace amount of vanadium in water was studied by flow injection analysis. Catalytic spectrophotometric detection was performed with bromate of o-phenylenediamine and by addition of tiron as an activator and also as a masking agent. Vanadium can be determined with sample rate of ca. 60-70 samples/hour with in a range of 0.01ppm to 0.5ppm V and with r.s.d. 0.55% for 0.1ppm V and 0.37% for 0.3ppm V. Interference by Fe(III) can be reduced by using 0.3% NH/sub 4/F as a carrier solution.
