Application of the Synthesized Activated Carbon-4A Zeolite Composite from Elutrilithe in Wastewater Treatment.

The quartz abundant elutrilithe with several other elements from Pan zhihua, was taken as the main material to synthesize activated carbon-4A zeolite composite by hydrothermal crystallization after alkali fusion at 750 °C for 1 h under a flowing N2 atmosphere. Then the effect of alkali content and molar ratio of H2O versus Na2O on product was investigated, respectively. Finally, the activated carbon-4A zeolite composite was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetry-differential scanning calorimetry (TG-DSC). The results showed that the crystallization product was activated carbon-4A zeolite composite with complete crystal form and the average particle size was about 1 μm. Moreover, the composite materials had well adsorption capacities to water, hexane and metal ions such as Cu2+, Ni2+, Zn2+ and Pb2+ analyzing by inductively coupled plasma atomic emission spectrometry (ICP).
