摘要
这是一篇陶瓷及复合材料领域的论文。羟基磷灰石(HAP)具有优良的离子交换性能,对废水中的重金属离子、有害阴离子及有机物表现出良好的吸附能力,在处理废水过程中不会造成二次污染,有望成为新型的绿色吸附材料。纳米羟基磷灰石(nHAP)由于尺寸小、比表面积大,暴露出更多的吸附位点,表现出优异的吸附能力。制备吸附能力强,易固液分离和再生,成本低的nHAP复合材料成为未来发展趋势。文章综述了近年来nHAP及其复合材料作为废水水处理吸附剂的研究进展,展望了其应用前景。
This is an article in the field of ceramics and composites.Hydroxyapatite(HAP)has excellent ion exchange performance,shows good adsorption capacity for heavy metal ions,harmful anions,and organics in wastewater,and will not cause secondary pollution in the process of wastewater treatment.Thus,it is a promising green adsorbent.Due to its small size and large specific surface area,nano-hydroxyapatite(nHAP)exposes more adsorption sites,showing supreme adsorption capacity.It is a tendency to produce nHAP composites of strong adsorption capacity,easy for solid-liquid separation and regeneration,and lowcost.This article reviews the recent research progress of nano-HAP and its composites as adsorbents for wastewater treatment,and prospects the application of them as adsorbents.
