Corrigendum to “Green Synthesis of S- and N-Codoped Carbon Nanospheres and Application as Adsorbent of Pb (II) from Aqueous Solution”

---

In the article titled “Green Synthesis of S- and N-Codoped Carbon Nanospheres and Application as Adsorbent of Pb (II) from Aqueous Solution” [1], the following issues were identified:(1)The description for the Langmuir model was incorrect and instead should state “The Langmuir model describes monolayer adsorption”(2)The description for the Freundlich model was incorrect and instead should state “The Freundlich model describes multilayer adsorption”(3)In Table 4, the value for q_m was incorrect and the value should instead be 101.1

The authors state the incorrect descriptions and value were introduced by error and confirm the descriptions and value given above are correct.
