Correction to: Scientific Reports https://doi.org/10.1038/s41598-023-42058-5, published online 13 September 2023

The original version of this Article contained errors. The represented data for the surface area and pore size of the resultant nano-magnetite were incorrect.

In the Abstract,

“Accordingly, HCl-based agitation leaching followed by co-precipitation was carried out, resulting in ultrafine mesoporous nano-magnetite (2.47–4.27 nm particle size, 120 m²g⁻¹ surface area, 0.55 cm³g⁻¹ pore volume, and 4.88 nm pore diameter) expected to serve in water treatment as an effective adsorbent for heavy metals.”

now reads:

In the Methodology, under the subheading ‘Chemical treatment and synthesis of nano-magnetite,

“For particle size, transmission electron microscope “TEM-JEOL” was implemented. Also, the total surface area and the distribution of pore size were studied by N₂-adsorption BET method that performed using Micromeritics ASAP 2020 at the National Research Center, Egypt.”

now reads:

“For particle size, transmission electron microscope “TEM-JEOL” was implemented.”

In the Results and discussion, under the subheading ‘Characterization of nano-magnetite’, “Surface area and pore size distribution” subsection was removed. Subsequently, Figures 14 and 15 and References 44 and 45 were removed.

Finally, in the Conclusion,

“Furthermore, it is distinguished by ultrafine particle size varying between 2.47 and 4.27 nm, pore volume of 0.55 cm³ g⁻¹, uniform pore diameter measured at 4.88 nm, and 120 m² g⁻¹ total surface area. Accordingly, the obtained nano-magnetite can be classified as mesoporous nano-particles that can be used as an effective adsorbent for water treatment applications.”

now reads:

"Furthermore, it is distinguished by ultrafine particle size varying between 2.47 and 4.27 nm. The obtained nano-magnetite can be used as an effective adsorbent for water treatment applications."
