摘要：
Chrome ions removal from aqueous solutions by adsorption onto an activated carbon (Aquacarb 207EA(TM) by Sutcliffe Carbon) and a South African coal char is illustrated. Different chrome concentrations, pH and salinity levels are tested. Experimental data are interpreted by means of a Langmuir approach-based model. Results show that a Permeable Adsorbing Barrier (PAB) made of Aquacarb 207EATM can protect a shallow aquifer from topsoil Cr(VI) leaching even during heavy rainfalls and that Cr(VI) is desorbed in dry periods, when clean water crosses the PAB, without any dangerous release in the aquifer.
