Evaluation of the Microsoft Excel Solver Spreadsheet-Based Program for Nonlinear Expressions of Adsorption Isotherm Models onto Magnetic Nanosorbent

Round 1

Reviewer 1 Report

The manuscript is devoted to interesting and most often used adsorption isotherms for pollutant removal in water and wastewater treatment. From the title of the article, it is clear that this article considers only the initial step of solving the different expressions of various two and three parameters equations. The work is well written and structured, contains a large number of tables and illustrative material, and is certainly of interest to a wide range of readers.

Reviewer 2 Report

The manuscript entitled Evaluation of Microsoft Excel Solver Spreadsheet-Based Program for Nonlinear Expressions of Adsorption Isotherm Models onto Magnetic Nanosorbent demonstrated magnetic nonasorbent was conducted isotherm adsorption studies. I think this is a useful article and I think it makes a potent scientific contribution. Aside from major edits, I'd want to see improved manuscript. I would recommend the manuscript for major revision. 

Here are general comments for the authors:

Introduction must be improved by incorporating more recent references and findings on the topic and by doing a comparison.

Importantly, it would be nice, if authors would show a schematic representation of the topics covered to improve the impact of this manuscript. Please address concise and clear scheme in a figure.

Please address chemical-physical properties of magnetic adsorbents used like TEM, DLS, magnetic property, and so on.

Introduction must be improved by incorporating more recent references and findings on the topic and by doing a comparison. 

Additional detail and references were addressed, please see in lines 63-65, 353-357. 

Importantly, it would be nice, if authors would show a schematic representation of the topics covered to improve the impact of this manuscript. Please address concise and clear scheme in a figure.

Figure 1 provides  the steps of operating, calculating, analysing and comparing in lines 164-165

Please address chemical-physical properties of magnetic adsorbents used like TEM, DLS, magnetic property, and so on.

Characteristics of magnetic nanosorbent and mechanism adsorption were explained in dept in the literature of Ref. [11] and mentioned in section 2 of materials and methods in Lines 62-63, 116-117.
