A Nickel-Containing Polyoxomolybdate as an Efficient Antibacterial Agent for Water Treatment
Round 1
Reviewer 1 Report
Comments to the Author
In this study ‘’A nickel-containing polyoxomolybdate as an efficient antibac-2 terial agent for water treatment’’
The article is written well, however, before publication will need more work.
Major corrections:
1. Insufficient characterization techniques. The author should add EDX and TEM of prepared polyoxomolybdate before and after treatment/adsorption to verify the structural changes in the complex.
2. Explain in detail the specific mechanism of antibacterial action of polyoxomolybdate complex.
3. The author should measure the recyclability study of polyoxomolybdate complex for basic fuchsin dye adsorption.
Minor corrections:
1. There are few typographical and grammatical errors in the manuscript. Hence, the manuscript should be carefully checked and necessary corrections should be done. Like ‘’In addition, 1 presented effective adsorption for basic fuchsin (BF) dyes.’’ Dye or dyes?
2. The purpose and novelty of the research should be added in the Introduction section.
3. ‘’Following the preparation of the original concentration of 1 (1 mg/mL), different concentrations were obtained by two-fold dilution in this assay’’. Which solvent is used for the preparation of dilution?
4. The adsorption of BF dye after first 30 min is too high and then become almost constant. Why?
5. ‘’Distinct adsorption capacity of 0.2 mg/mL, 0.4 mg/mL and 0.8 mg/mL with the 199 removal ratio of 69.6 %, 79.9 %, and 67.2 % in the dark of 90 min.’’ Why the adsorption ability decreases with increasing adsorbent concentration from 0.4 mg/mL to 0.8 mg/mL?

Reviewer 2 Report
In my opinion the paper with title: “
“A nickel-containing polyoxomolybdate as an efficient antibacterial agent for water treatment” should be published in the International Journal of the Molecular Sciences if the authors will make the following corrections and specifications.
Please enter the meaning of all abbreviations used at their first mention in the text.
For example, MIC – Chapter-Introduction, LMCT (line 122), MB, GV, line 207, etc.
Please write the name of the microorganism species in the same way in the text (usually Italic).
Please enter the name of the parameter that varies in the legend, on the figures
For example, in figure 2 D., the meaning of the numbers that are mentioned in the Legend (pH) is not presented
In accordance with the Instructions for Authors in the paper at the Chapter Materials and Methods: “They should be described with sufficient detail to allow others to replicate and build on published results. New methods and protocols should be described in detail while well-established methods can be briefly described and appropriately cited. Present the name and version of any software used and make clear whether computer code used is available. Include any pre-registration codes”
The Materials and Methods chapter is very poorly represented in this article.
Please present a detailed description of the working method and working conditions for each type of experiment,
Please specify the mathematical equations used and the meaning of the parameters to describe the studied processes.
Please specify the type and manufacturer of the equipment and reagents used, etc.
Also, you should present the calculation relationships for different sizes whose variation was represented or mentioned in the text, for example for the degree of dye removal
Please mention the size range of the solid crystals used in the experiments.
Also, mention how to ensure a certain pH value.
What is the working method and the working conditions through which the stability of the crystals was highlighted in various conditions?
