Effects of Temperature and Sulfuric Acid and Iron (II) Concentrations on the Efficacy of Decontamination of Spent Ion-Exchange Resins Containing Hematite
Round 1
Reviewer 1 Report
Comments to authors are below:
- The title is long and should be modified.
- Authors should report the significant findings with numerical values in the abstract section.
- The applications and novelty should be justified clearly in the last paragraph of the introduction.
- The discussion of results is limited and not well organised and the data presented in this study is not enough to make scientific impact for publishing.
- Figure 11 shows no clear data plotting. Authors should re-draw the data and interpret all differences clearly.
- Conclusions should be reported significant findings of results presented.

1. The title is long and should be modified. «Study on the effect of the concentration of sulfuric acid and iron(II) and the temperature of a solution on the efficiency of decontamination of spent ion-exchange resin contaminated with hematite»
Answer The title was change« Effects of temperature and sulfuric acid and iron (II) concentrations on the efficacy of decontamination of spent ion-exchange resins containing hematite»
2. Authors should report the significant findings with numerical values in the abstract section.
Answer
Thanks to the Reviewer for the comment. We have rewritten the abstract.
3. The applications and novelty should be justified clearly in the last paragraph of the introduction.
Answer
Thanks to the Reviewer for the comment. We've adjusted the introduction and added some text. The relevance and novelty is due to the fact that information on the effect of iron(II) on the efficiency of SIER decontamination with sulfuric acid solutions upon heating is not presented in the literature. The use of iron(II) rather than organic complexones can simplify the recycling of secondary waste.
4. The discussion of results is limited and not well organised and the data presented in this study is not enough to make scientific impact for publishing.
Answer
We are grateful to the Reviewer for the comment. Figures 8, 9, 10 were compiled into one table 2. Only the DF values after the additional wash with NaNO3 were retained. Some changes have been made to the text.
5. Figure 11 shows no clear data plotting. Authors should re-draw the data and interpret all differences clearly.
Answer
We thank the Reviewer for a valuable comment. An error was made in the caption of the figure; in this experiment, a 0.1 M solution of H2SO4 was used. The figure has been replaced by Table 3. The results shown in Table 3 show that the use of 0.1 M H2SO4 solution is not effective even when iron(II) is added and heating.
6. Conclusions should be reported significant findings of results presented.
Answer
We are grateful to the Reviewer for the comment. The conclusion has been corrected.
Reviewer 2 Report
Study on the effect of the concentration of sulfuric acid and iron(II) and the temperature of a solution on the efficiency of decontamination of spent ion-exchange resin contaminated with hematite
I suggest to shorten the title and make it more concise:
Effects of temperature, sulfuric acid, and iron(II) concentration on decontamination efficacy of hematite contaminated spent ion-exchange resins.
Page 1 Line 31: Unfinished sentence.
Page 2 Line 48: I would suggest to put the name of the authors e.g. Leybros et al, not only the reference.
Page 7 Figure 6: The error bar is cut off.
English language is very good.
Structure of the manuscript es also very good.

Answer
We are grateful to the Reviewer for the comment. The figure has been corrected.
Reviewer 3 Report
Article was well presented.
Add the sensitivity of thermocouple used in the research.
Also add how repeatability of the experiments was maintained.
In Line 292, is it 50 degree or 70 degree?
Author Response
- Add the sensitivity of thermocouple used in the research.
Answer
We are grateful to the Reviewer for the suggestion, however, the manuscript already contains a mention of a temperature measurement error. Page 4 "The temperature measurement error was 1-3 oC".
- Also add how repeatability of the experiments was maintained.
Answer
We are grateful to the Reviewer for the comment. Additions were made to the text of the manuscript.
- In Line 292, is it 50 degree or 70 degree?
Answer
Text was corrected
