Wastewater treatment remains a critical issue globally, despite various technological advancements and breakthroughs. The study of different materials and technologies gained new valences in the last years, in order to obtain cheap and efficient processes, to obtain a cleaner environment for future generations. In this context, the present review paper presents the new achievements in the materials domain with highlights on apatitic materials used for decontamination of water loaded with heavy metals. The main goal of this review is to present the adsorptive removal of heavy metals using hydroxyapatite-based adsorbents, offering a general overview regarding the recent progress in this particular area. Developing the current review, an attempt has been made to give appropriate recognition to the most recent data regarding the synthesis methods and targeted pollutants, including important information regarding the synthesis methods and precursors, morphological characteristics of the adsorbent materials and effectiveness of processes.
尽管有各种技术进步和突破，但废水处理在全球范围内仍然是一个关键问题。在过去几年中，对不同材料和技术的研究有了新的意义，以便获得廉价且高效的工艺，为子孙后代创造更清洁的环境。在此背景下，本综述文章介绍了材料领域的新成就，重点介绍了用于去除重金属污染水的磷灰石材料。本综述的主要目的是介绍使用羟基磷灰石基吸附剂吸附去除重金属的情况，概述该特定领域的最新进展。在撰写本综述时，已尝试对有关合成方法和目标污染物的最新数据给予适当认可，包括有关合成方法和前驱体、吸附剂材料的形态特征以及工艺有效性的重要信息。
