Review Reports - Sustainable Recovery of Valuable Nanoporous Materials from High-Chlorine MSWI Fly Ash by Ultrasound with Organic Acids

Round 1

Reviewer 1 Report

In this manuscript, authors used a acid with assisted ultrasound to eliminate Cl from fly ash.The method has the engineering value, and it could help improve the Municipal solid waste. But, there was some problems to be solved.

1 the ultrasound power should be given in paper, the power was very important for the removal efficiency of Cl.

2 in section 2.4.3, it mentioned the ratio were 1:2.5, 1:5, 1:7.5, and 1:10, but the good result was 1:10, the result of 1:15 or 1:20 need to add, or else the ‘The S/L ratios ranged between 1:1 and 1:20 and the results indicated that 1:10 was the optimal ratio for Cl leaching’ was not supported by the manuscript investigation.

3 in fig.7, the noise was obvious, it was suggested data denoising.

4 in table.4, the ultrasound power should be given, it was important data. If power was different, the results may be varied.

1) Title: Sustainable recovery of valuable nanoporous materials from high-chlorine MSWI fly ash by ultrasound with organic acids

Comment: Please include the statements about "valuable nanoporous" in the manuscript.

2) Line 136. surface area provided in the text does not match with the one you mentioned in Table 1.

3) please cite the paper from where you received the information that you provided in Table 1

4) Line 163. Please mention in the text what delta values stands for

5) Line 167. Why did you cite a reference there [37].

6) Table 2 What are those A, B, C, and D

7) Line 223 Please include a reference

8) Figure 5. why the scale is different for the raw fly ash?

9) Figure 6. Why the scales are different sometimes 5 or 10

10) Line 423. Delete "analytical methods"

11) section 3.4 You need elaborate on this part. Please provide more information

12) On what basis do you choose those ranges (levels) for each factor in table 5. if you chose those ranges from some studies, please cite those papers.
