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。用实验结果和计算化学相结合的方法研究了各种阴离子对水钙矾石和钙矾石的选择性。氢化钙石中固定的阴离子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由阴离子的水化能力控制。评价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材料的开发。在此基础上，我们总结了一项相关工作，并将在国际期刊上发表。鉴于波特兰水泥在固定污染物方面存在相容性低、凝结时间长等缺陷，我与国际上一些研究机构合作开发了基于选择性研究的新型固定材料。我们已将这种材料用于固定一些工业废料。通过实验，我们发现该材料在固定化污染物方面表现出优异的性能。这种材料可用于处理各种污染物。

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.
