[ Method] FeCl3 solution with different concentrations was used to modify sepiolite. By static adsorption experiment, the adsorption capability of Fe modifying sepiolite on Cr（VI ） was studied. [Result] Under the condition of initial Cr（VI） concentration of 90 mg/L, 10.0% IMS dosage of 5 g/L, pH of 4.5, adsorption time of 90 min, and temperature of 25 ℃ the equilibrium adsorption quantity of Fe modifying sepiolite was 6.5 mg/g. [Conclusion] The research provided an effective pathway for the application of Fe modifying sepiolite in Cr（VI）-containing wastewater treatment.展开更多
