摘要

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.
