Abstract

The rapid expansion of nuclear energy has led to increased uranium contamination in wastewater, necessitating the development of efficient, cost-effective, and recyclable materials for uranium removal. Hydroxyapatite (HAP) has emerged as a promising candidate due to its exceptional surface properties, structural tunability, and environmental compatibility. This review systematically evaluates recent progress in HAP-based materials for uranium remediation, focusing on advanced synthesis techniques and modification strategies that enhance adsorption capacity and ion selectivity. We analyze the underlying mechanisms, particularly the roles of material morphology and solution pH in optimizing uranium removal efficiency. Current limitations in practical applications are critically discussed, along with future research priorities for developing next-generation HAP composites. By establishing structure-performance relationships and addressing current challenges, this review provides fundamental insights to guide the design of high-performance radioactive wastewater treatment materials.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
