Reviewer 2 Report
-The abstract requires inclusion of quantitative results to better illustrate the study's findings.
-The introduction would benefit from further elaboration to provide a more comprehensive overview of the study's background, objectives, and significance.
-The quality of images depicting TG (Thermogravimetric Analysis) and DTR (Dynamic Thermal Analysis) is insufficient. Please enhance the clarity and resolution of these images for better interpretation.
-Kindly include the distribution of pore size data to provide insights into the porous structure of the material studied.
- It is essential to include fitting curves of kinetic and isotherm data, aligned with appropriate models, to enhance the understanding of adsorption behavior.
- The inclusion of the Vant Hoff curve is necessary to provide additional insights into the thermodynamic aspects of the adsorption process.
- It is crucial to include the mechanism of adsorption and comprehensive characterization of the adsorbent post-adsorption to elucidate the various interactions between the adsorbate and adsorbent.
- The assessment of reusability and regeneration of the adsorbent is essential and must be included to evaluate its practical applicability.

Reviewer 3 Report
The manuscript introduces a magnetic bioadsorbent created through simple physical and chemical processes for the adsorption of acetaminophen (ACE) from aqueous solutions. Notably, this material exhibited exceptional performance in ACE adsorption. Additionally, the study delves into various adsorption kinetic models, namely the Elovich model, yielding highly favorable fitting results. These promising outcomes establish a sturdy theoretical basis for the exploration of such substrates in line with green chemistry principles. The manuscript's thoroughness and depth render it suitable for publication in C. However, some revisions are necessary for acceptance. Specific suggestions are outlined below:
1. 199 Line: The clarity of Figure 2 is inadequate. Please replace it with a clearer version.
2. 251 Line: “After activation, no broad peak associated with the presence of graphite disappears completely as a consequence of the disorder of the graphene layer which results in the development of porosity”, the sentence fails to convince me. Please provide corresponding reference support.
3. 379 Line: The legends in Figure 9 and the corresponding figure overlap. Please rearrange them.
4. 31 Line: The introduction information provided is insufficient. It is recommended to incorporate more articles to enrich the context.
