In this paper the removal of chromium from Cr/Ca/Mg/K and Cr/Ca/Mg/K/Na solutions was investigated in NaX and NaY packed beds. The breakthrough curves presented some overshooting phenomena where chromium ions displaced the previous exchanged cations. Len...

Neste trabalho foi investigada a remoção de íons Cr3+ pelas zeólitas NaA e NaX, em condições de equilíbrio e em sistemas dinâmicos, a 30oC. Os fatores de separação, obtidos a partir dos dados em equilíbrio, mostraram-se muito próximos para as isotermas C...

In this paper, the chromium uptake in zeolites NaA and NaX was investigated in equilibrium condition and in dynamic systems at 30oC. The separation factors, obtained from the equilibrium data, were very similar to the isotherms Cr-NaA e Cr-NaX, which ind...
