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

初步研究了阴离子对胶凝材料的选择性。结合实验结果和计算化学研究了不同阴离子对水铝钙石和钙矾石的选择性。水铝石中阴离子的固定主要取决于其阴离子半径和水化能力。然而，阴离子对钙矾石的选择性通常由阴离子的水合能力控制。这些氢氧化物的阴离子的性能进行评估，了解迁移行为，也适用于开发新的固定化材料。在此基础上，我们总结了一项工作，并将在国际期刊上发表。考虑到波特兰水泥存在的一些缺陷（相容性差、凝结时间长等），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。我们已用这种材料处理了一些工业废料。通过实验，我们发现该材料对污染物的固定化表现出了优异的性能。该材料可应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.
