摘要：
Mg3Fe-LDHs was synthesized by co-precipitation and characterized by XRD, DTA technologies. Then the calcined product of synthesized sample (Mg3Fe-LDO) was applied in adsorption of the simulative Cr(VI) waste water. The influence of adsorption time, solution initial pH value, Cr(VI) concentration and temperature have been tested. The optimal adsorption conditions are got as follows: adsorption time is 60 min, solution initial pH value is 6, temperature is 50 degrees C, and Cr(VI) concentration is 100 mg/L. Under the optimal condition, the maximum adsorption capacity of Mg3Fe-LDO reaches 71.12 mg/g, which is better than the traditional adsorption materials obviously.
