摘要：

In this study, Kinetics of uptake of Ni2+ by Mg-Al layered double hydroxides (Mg-Al LDHs) intercalated with CO32- and NO3- in the interlayer were examined. At first Mg-Al NO3 LDHs and Mg-Al CO3 LDHs with a Mg/Al ratio of 2, 3 and 4 were synthesized, using a constant-pH co-precipitation method. According to XRD and FLIER, the solid products were found to have the layered structure. Mg-Al LDHs were found to have a capacity for rapid uptake of Ni2+ from an aqueous solution. Mg-Al CO3 LDHs have bigger area and preferable adsorptive capacity. The adsorption rate of Mg-Al CO3 LDHs is faster moreover. The sorption Kinetics can be successfully fitted by pseudo-second order equation.
