文摘

Investigated are processes of sorption–desorption of Cr(IV) on model to the efficiency of desorption of Cr(VI) from the sorbent reagents are arrange in the series (NaOH: Na₂CO₃) > NaOH > Na₂CO₃ ≥ H₂CO₃ ≥ H₂SO₄. Calcined Zn/Al–hydrotalcite has been proposed for concentration of Cr(VI) and its spectrophotometric determination in natural waters.
