Abstract

Composites of hydroxyapatite, recognized by its peculiar crystal architecture and distinctive attributes showcased the potential in adsorbing heavy metal ions and radioactive elements as well as selected organic substances. In this paper, the intrinsic mechanism of adsorption by composites hydroxyapatite was proved for the first time. Subsequently, selectivity and competitiveness of composites of hydroxyapatite for a variety of environments containing various interferences from cations, anions, and organic molecules are elucidated. Next, composites of hydroxyapatite were further categorized according to their morphological dimensions. Adsorption properties and intrinsic mechanisms were investigated based on different morphologies. It was shown that although composites of hydroxyapatite were characterized by excellent adsorption capacity and cost-effectiveness, their application is often challenging due to inherent fragility and agglomeration, technical problems required for their handling as well as difficulty in recycling. Finally, to address these issues, the paper discusses the tendency of hydroxyapatite composites to adsorb heavy metal ions and radioactive elements as well as the limitations of their applications. Summarizing the limitations and future directions of modification of HAP in the field of heavy metal ions and different substances contamination abatement, the paper provides insightful perspectives for its gradual improvement and rational application.

羟基磷灰石复合材料及其在吸附、医药和催化剂方面的应用

羟基磷灰石复合材料因其奇特的晶体结构和独特的属性，在吸附重金属离子、放射性元素和特定有机物方面具有巨大潜力。本文首次证明了羟基磷灰石复合材料的内在吸附机理。随后，阐明了羟基磷灰石复合材料对各种含有阳离子、阴离子和有机分子干扰的环境的选择性和竞争性。接下来，根据羟基磷灰石复合材料的形态尺寸对其进行了进一步分类。根据不同的形态研究了吸附特性和内在机制。研究表明，尽管羟基磷灰石复合材料具有出色的吸附能力和成本效益，但由于其固有的脆弱性和团聚性、处理所需的技术问题以及回收困难，其应用往往具有挑战性。最后，针对这些问题，本文讨论了羟基磷灰石复合材料吸附重金属离子和放射性元素的趋势及其应用的局限性。本文总结了羟基磷灰石复合材料在重金属离子和不同物质污染消减领域的局限性和未来改性方向，为其逐步完善和合理应用提供了深刻的视角。
