摘要：

The first protonation constant for VO3-4 has been determined spectrophotometrically at 25° in 1M sodium chloride and found to have the value log K = 13.29 ± 0.01. Individual absorption spectra for VO3-4 and HVO2-4 have been calculated (for the range 218-350 nm) from experimental absorbance measurements. © 1990.
