内容简介

　　本书凝聚了作者多年的科研成果，在理论和应用方面都进行了深入地论述和创新。第1章介绍了新兴污染物高氯酸根的生物毒性与相关处理技术，分析了有机改性蒙脱石在环境修复中的应用与研究现状。第2章概括了本书涉及的固相表征技术及吸附模型。第3章通过甄选六种不同分子结构的传统有机季铵盐为蒙脱石改性剂，探究了改性剂分子结构对高氯酸根吸附的影响机制。第4章研究了改性剂使用量与高氯酸根吸附特征之间的关系，考察了改性蒙脱石的吸附稳定性。第5章通过同位与异位改性对比，开展未干燥与干燥对高氯酸根吸附的影响试验，研究了季铵盐溶出的抑制机制，揭示了改性蒙脱石对高氯酸根吸附除离子交换之外的脱附/再吸附机理。第6章系统地研究了季铵盐改性蒙脱石对多种无机阴离子吸附选择性的决定因素，即吸附位点所处环境介电常数及目标阴离子吸附前后的水合半径。第7章深入研究了改性蒙脱石对典型阴/阳离子型放射性核素的同步吸附特征，揭示了脱附/再吸附是Sr（II）与Re（VI）协同吸附的主要原因。第8章利用了分子层面的物理包裹策略，在有效抑制季铵盐溶出的同时，实现了阴/阳无机离子的协同吸附，论述了海藻酸盐/有机蒙脱石复合材料在复杂污染水体修复中的应用前景。以上工作由江西理工大学罗武辉、黄祈栋、袁秀娟和任嗣利共同完成，罗武辉负责文字撰写、内容统筹与数据解译，黄祈栋和袁秀娟负责数据收集、图形制作与润色，任嗣利负责材料表征分析。
