The new opinion and mechanism that the simultaneously adsorption of complex pollution of both organic and heavy metals will be achieved on soil modified with amphoteric surface modifying agent, which have both charged group and organophilic group on one ASMA molecule, were proposed at first time, and its rationality was testified at the same time; The 50% was the critical CTMAB modifying ratio of soil CEC at which the organophilic bond modifying mechanism was emerged; The thermodynamic characteristics of adsorption of OPT and HMP on OMS were discovered ; The study revealed the surface peculiarity of OMS that the modifying agent were distributed at uneven scatter mode and multi-characters surface were coexisted on surface of OMS, revealed the adsorption peculiarity of OMS that multi-mechanisms were coexisted, confirmed the unequal charge amount modifying mode of OMS in which dual-modifying mechanism of both ion exchange and OPB were processed at the same time, and confirmed that the adsorption hobby to CTMAB was higher than that to Ca2+ on Lou soil.
首次提出了用两性表面修饰剂对土壤进行修饰改性,利用两性表面修饰剂所具有的荷电基团和疏水基团达到对土壤中有机、重金属污染物同时吸附的思路和机理,并通过实验证实了所提设想的合理性;发现了土壤CEC值的50%修饰比例是CTMAB开始显现以疏水键机制对土土样表面进行修饰的临界点;揭示了有机修饰改性土对有机物、重金属吸附过程的热力学特征,填补了该项研究工作的空白;阐明了修饰剂在改性土表面呈分散态的非均匀分布,改性土表面具有不同性质表面共存的表面特征和对污染物多机制共存的吸附特征,确定了阳离子表面修饰剂在土表面的修饰是一种离子交换和疏水键结合两种机制相伴并行且为非等电荷量交换的修饰反应模式,以及土具有对CTMAB的吸附偏好性远大于对钙离子吸附偏好性的特征。

Pillared montmorillonite, as a representative of Sandwich like pillared interlayered clays ,caught many scientist"s attention not only because of its special structure of two-dimensional sheets but also its excellent activity of catalysis and adsorption. It is well documented that the method to prepare PILM, ion-exchanging, needed a long periods and was affected by many factors, and that the product had low thermal stability especially hydro-thermal stability which was the primary obstruction of its using in large-scale production. At the same time, PILM was well documented prepared with Na-montmorillonite, while there were a few documents about PILM prepared with Ca-montmorillonite. The large cost of remodel of Ca-montmorillonite to Na-montmorillonite was another obstacle of the application of PILM, while Ca-montmorillonite was widely distributed in nature, as a result, to prepare PILM with Ca-montmorillonite has practical significance. What"s more, PILM was mainly studied as a catalyst in oil refining process till now, but rarely documented in other catalysis reactions, especially in coal liquification filed which also needed high activity catalyst.
以柱撑蒙脱石为代表的具有&三明治&结构的柱撑粘土矿物因其特殊的二维孔道结构和优良的催化和吸附性能近年来成为国内外广泛关注和研究的热点,但是目前国内外大量报道的PILM制备大多采用离子交换法,生产周期很长,影响因素很多,并且产物热稳定性不够高,特别是水热稳定性较差,这是其不能在实际中大规模生产和应用的主要障碍,因此制备一种高稳定性的PILM意义非常;文献中大量报道的都是钠基蒙脱石合成的柱撑粘土矿物,传统的离子交换法必须将钙基蒙脱石钠化改型,其成本相当高,而自然界中大量存在的却是钙基蒙脱石,直接用钙基蒙脱石合成柱撑粘土矿物有很现实的意义,但目前这方面的报道却很少见;另外,迄今为止,PILM作为催化剂的研究领域主要在石油的炼制中应用,而在煤炭的液化中却鲜有报道,如果能在煤炭转化领域应用这一成果,其影响也将是相当大的。
