Abstract


The raw montmorillonite which was supplied by Shandong Shouguang Fine Montmorillonite Co.Ltd, A wet modification was used to calcium montmorillonite change Sodium montmorillonite by ion exchange. Ferrosilicon pillars agent with different concentration were preparaed by copolymerization method. Ion exchange method to take Na-montmorillonite ferrosilicon pillared montmorillonite. Simulated wastewater with 25mg/L in the Cr (VI) adsorption by ferrosilicon pillared montmorillonite at adsorbent concentration. and the effects of temperature, pH, adsorbent dosage, adsorption time and dosage of different columns of ferrosilicon pillared montmorillonite on Cr(VI) adsorption efficiency were-investigated.
