Round 1

Reviewer 1 Report

The paper investigated the adsorption of two heavy metals from synthetic solutions using different porous nanomaterials. The adsorbents materials were characterized and the artificial neural network was used to propose predictive models based on the experimental results.

 Authors have used absorption throughout the paper to describe the removal process of heavy metals into the porous materials. However, adsorption is the appropriate process.

The originality of this pape ris not well described.

Please provide in the material and methods section the methods for the characterisation of the pours materials.

Please provide in the material and methods section the  artificial neural network architecture and the used algorithm.

Figure 1. Please provide the four XRD patterns in the same scale and in one figure.

Authors should characterise the adsorbent materials after adsorption to provide more information about the adsorption mechanisms involved to remove heavy metals. In addition, isotherms and kinetics should be also investigated to determine the type of adsorption.

Minor editing of English language required.

Reviewer 2 Report

The manuscript was well written and designed, and the authors got interesting results. However the work needs some enhancements before it can be published. I recommend minor revision of the manuscript based on the following comments:

- Due to the scope of the journal, the authors should discuss the durability of the nanomaterials used, the possibility of their reuse and the final management together with the retained lead and cadmium ions.

-  The methodology should include the parameters of the reagents used (purity, manufacturer) and the laboratory equipment used (producer, country of production).
