  • 摘要: 以季铵盐阳离子表面活性剂CTMAB及阴离子表面活性剂SDS对粉末状天然沸石进行复合改性,制备得到了CTMAB/SDS改性沸石。对改性沸石及天然沸石进行红外吸收光谱及XRD衍射表征,并研究了PAEs在天然沸石和CTMAB/SDS改性沸石上的吸附机制。结果表明,阴阳离子表面活性剂没有对层状结构的键型造成较大的影响;PAEs在天然沸石和CTMAB/SDS改性沸石上的吸附更符合表面吸附-分配作用复合模型;PAEs的表面吸附和分配作用对吸附作用的贡献主要受吸附剂中有机质含量及吸附物质大小、极性及溶解度的影响。
    Abstract: The cetyltrimethylammonium bromide (CTMAB) and sodium dodecyl sulfate (SDS) modified zeolite were prepared to investigate their adsorption capabilities in the removal of phthalic acid esters (PAEs) substances from aqueous systems. The natural and CTMAB/SDS modified zeolites were characterized with X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The mechanisms of PAEs sorption by the the natural zeolites and CTMAB/SDS modified zeolites were evaluated. Results show that bond type variation phenomenon of layer structure in the CTMAB/SDS modified zeolites was not significant compared with the natural zeolite. The experimental isotherm data fitted more well to Dual Adsorption-Partition model than Langmuir, Freundlich and Linear model. The relative contribution of adsorption and distribution in the sorption of PAEs on the zeolites is mainly influenced by two aspects: the level of the organic matter content in absorbent; the size, polarity and solubility of the adsorbate.
