Fast Removal of Chromium from Industrial Effluents Using a Natural Mineral Mixture

The use of a naturally available mineral mixture (MM) for the removal of chromium from industrial effluents has been investigated. Adsorption of chromium on MM from aqueous solutions is reported, and the effect of equilibration time, temperature, hydrogen ions, adsorbent and adsorbate concentration...

Zusammenfassung:	The use of a naturally available mineral mixture (MM) for the removal of chromium from industrial effluents has been investigated. Adsorption of chromium on MM from aqueous solutions is reported, and the effect of equilibration time, temperature, hydrogen ions, adsorbent and adsorbate concentration and foreign ions is discussed. The contact time required is less than 10 min and the adsorption capacity is 45 g/kg of sorbent.
