摘要：
Adsorption of Cr(VI) from aqueous solution by natural sepiolite was studied. Experiments were carried out at continuously operating packed beds. Adsorption yields were determined by distribution curves plotted as chromium removal concentrations versus time. Effects of factors, such as pH, temperature, concentration and flow rate on adsorption yield were investigated. It was conclusively observed that the yield decreased with increasing liquid flow rate. Effects of pH, temperature and concentration on yield did not show a steady tendency.
