Development of new immobilization technique through investigation on the immobilization selectivity between cement related materials and anionic pollutants

初步考察了阴离子对胶凝材料的选择性。将实验结果与计算化学相结合，研究了各种阴离子对水方解石和钙矾石的选择性。负离子在水合方解石中的固定主要由阴离子半径和水化能力决定。然而，阴离子对钙矾石的选择性一般受阴离子水化能力的控制。评价了阴离子对这些氢氧化物的迁移行为，并将其应用于新型固定化材料的开发。在此基础上，我们总结了一项工作，并将在国际期刊上发表。考虑到硅酸盐水泥存在配伍性差、凝结时间较长等缺陷。在污染物的固定化方面，我与一些国际研究机构合作，开发基于选择性研究的新型固定化材料。我们已经用这种材料固定了一些工业废物。通过实验发现，该材料在固定污染物方面表现出了优异的性能。该材料可用于各种污染物的处理。

The selectivity of the anions to cementitious materials is initially investigated. The selectivity of various anions to hydrocalumite and ettringite is studied by a combination of experimental results and computational chemistry. The anions immobilized in hydrocalumite are mainly determined by the anionic radius and hydration abilities. However, the selectivity of anions to ettringite is generally controlled by the anions' hydration ability. The performance of anions to these hydroxides are evaluated for understanding the migration behavior and also applied for development of new immobilization materials. Based on these, we have summarized one work on this and will be published in international journals. Considering the Portland cement have some defects (low compatibility, longer setting time, etc.) on the immobilization of pollutants, I have collaborated with some international research institutes on developing novel immobilization materials based on selectivity research. We have applied this material to immobilize some industrial wastes. Based on the experiments, we found this material exhibits outstanding performance on the immobilization of pollutants. This material could be applied for the treatment of various pollutants.
