本文研究格（ＶＩ）吸收光谱，提出在碱性介质中，直接光度法测定钢渣、钒渣及钒钛磁铁矿中铬，准确度高、精密度好、简单、实用。 In this paper, the absorption spectra of the lattice (VI) were studied. It was proposed that the determination of chromium, vanadium slag and vanadium-titanium magnetite in the alkaline medium by direct photometric method is of high accuracy and precision, simple and practical.
