Nano-PAA-CuCl2 Composite as Fenton-Like Reusable Catalyst to Enhanced Degrade Organic Pollutant MB/MO
Round 1
Reviewer 1 Report
1. In the text of the Abstract and page 2, line 76, the authors use the abbreviation without explanation. According to the rules for the article's preparation of any journal, it is necessary to explain the abbreviations used before their first mention in the text.
2. Page 3 line 120: Please check the country of the pH-meter manufacturer.
3. Page 5: How can the authors explain the absence of any peaks on XRD patterns?
4. Page 5 line 191: Why did the authors choose an initial acidity value of 3? The authors could explain the choice of the acidity value of the solution earlier than on pages 9-10.
5. Page 5: Did the authors record the weight loss of the catalyst upon reuse?

Reviewer 2 Report
The authors developed a novel catalyst using a nano-PAA-CuCl2 nanostructure for the removal of dyes (MO and MB) from the textile industry by a Fenton process. The manuscript stands out for its high level of characterization of the novel material. In addition, the authors evaluated the reuse of the material, offering satisfactory results. It was a good read, I liked the article, and I recommend it for publication after some minor corrections:
-In Section 2.2, attach a figure to help the reader to reproduce the synthesis procedure of novel catalyst.
-In Figure 3, indicate to which crystalline phase each diffraction peak corresponds. Can you indicate the dispersion (%) of the metallic phase in the substrate?
-Delete the paragraph from lines 182-186. It is not necessary for the understanding of the study.
-In Figure 4, combine figures a and b, as well as c with d, so that readers can easily compare the different configurations.
-In Eq. 1, indicate above the arrow pH=12.0
-Correct the typographical error (line 418), Figure 14?
-Correct this typographical error "·OH" throughout the manuscript and figures, according to the IUPAC standard (HO·).
