摘要
A new nano composite matertal of EDTACo-MgAl layered double hydroxides (EDTACo-MgAl-LDHs) was synthesized in the ways of coprecipitation. Then, X-ray diffraction(XRD) and inductively coupled plasma(ICP) were used to characterize the properties of the material. The azo dye reactive black 5 was chosen as a target pollutant to study the effects of initial pH, concentration of target pollutant and temperature on adsorption. Finally, the properties of EDTACo-MgAl-LDHs as catalyst for Fenton reaction were discussed preliminarily. It is found that the maximum equilibrium adsorption was 330 mg·g-1 under the conditions of normal temperature and neutral pH. The catalytic oxidation and adsorption efficiency was complementary with increasing pollutant concentration. The total removal efficiency reaches up to 90% with the initial pollution concentration range of 120~360 mg·L-1. © 2017, Editorial Department of Journal of Tongji University. All right reserved.
