Fixed bed adsorption column studies were carried out to assess the breakthrough performance of the polypyrrole-organically modified montmorillonite clay (PPy-OMMT NC) for removal of toxic Cr(VI) from water. The effects of bed mass, initial Cr(VI) concentration and flow rate on the bed performance were evaluated and a notable bed performance (3.2 L treated water) was achieved at high bed mass, low inlet Cr(VI) concentration and flow rate. Experimental data agreed well with the Thomas and Yoon-Nelson model. Based on performance data, it can be concluded that the PPy-OMMT NC is a competitive sorption media for Cr(VI) removal from aqueous environments.
