Scope

This standard specifies the graphite furnace atomic absorption spectrometry for the determination of vanadium in wastewater. This standard applies to the determination of vanadium in wastewater. The measuring range is related to the characteristics of the instrument used. The measuring range of general instrument is 0.05～1.0mg/L. Coexisting ions and compounds in wastewater do not interfere with the determination at common concentrations, but when the concentration of vanadium is 1mg/L, while the concentration of lead and molybdenum exceeds 300mg/L, and the concentration of iron exceeds 200mg/L, the concentration of arsenic, antimony and bismuth When the concentration exceeds 100mg/L, when the concentration of nitric acid exceeds 6% (V/V), it will inhibit the absorption of vanadium and make the determination result of vanadium low.
