Corrigendum to “Environmentally benign and novel management route for radioactive corrosion products by hydroxyapatite” [J. Nucl. Mater. 507 (2018) 218–225]

Efficient immobilization of ionic corrosion products by a silica-hydroxyapatite composite via a cold sintering route

“…36 HAp is a well-known sorbent for trapping monovalent and divalent metal ions from aqueous media. 3,37,38 A detailed sorption study on the optimization of the HAp powder dose to remove a maximum amount of metal ions from a mixture may be found in our previous study. 3 Briey, 40 g L À1 HAp powder was found sufficient to remove more than 95% of the metal ions (Co, Cr, Cu, Fe, Mn, Ni, and Zn) with a total concentration of 7 mM at pH 6.…”

“…The smart use of a variety of natural and anthropogenic wastes to capture and immobilize radioactive wastes could be an innovative technology to solve the gigantic environmental problems in an efficient and effective manner. [1][2][3] The nuclear power industry has grown strongly in the past 50 years to meet global energy needs. According to the report from International Atomic Energy Agency (IAEA) 2018, about 448 nuclear power reactors with a total installed capacity of 391.721 GWe are in operation worldwide.…”

“…Both constituents of the composite (EDTA-Si and HAp) are readily available and possess ion exchange properties. 3,[18][19][20][21] HAp is the most important bioactive material with many natural sources in the form of minerals, phosphate-based rocks, and animal and sh bones. 22 It can easily be synthesized by co-precipitation, sonochemical and hydrothermal methods and is commercially available as well.…”

“…HAp was also studied and reported for its crystal structure exibilities to incorporate and hold a number of cationic and anionic species. 3,24 Silica has been used as a thickening agent to reinforce and improve the mechanical properties of nanomaterials. 25 Silica-reinforced calcium hydroxyapatite has been synthesized for dentistry and biomedical applications.…”

“…[28][29][30][31] The immobilization of radioactive wastes by HAp has also been suggested elsewhere. 3,32 Nevertheless, the sorption, solid-state mixing, and solidication properties of two spent wastes (metal ion captured silica and HAp) are the least investigated. Additionally, high-temperature sintering has certain disadvantages, such as the volatilization of sorbed volatile radionuclides, the dehydroxylation of hydroxyapatite to form unwanted apatite phases (b-TCP), and the high processing cost.…”
