Title: Efficient removal of azlocillin sodium from water by polysty-2 rene anion exchange resin supported MIL-53

 

Recommendation: minor revisions noted.

 

 

In this manuscript, authors fabricated MIL-53/D201 composite material and used it for the sorption of azlocillin sodium in water. The preparation method of the composite was systematically studied by investigating the microstructure, surface properties and internal structure of the composite. The adsorption effect of the composite on azlocillin sodium in solution was studied. This study provides an idea for the fixation of MOF materials into stable carriers, and this composite adsorbent material can be used as a potential material for the degradation of target anionic pollutants in water.

The originality of this work is validated, presenting an up-to-date literature review in the Introduction section. The experimental design is adequate and the results provide significant contributions to this journal. The discussion is logically organized and no stretching of the interpretation is found. Specific comments are listed below.

 

 

Comments

 

  1. There are many figures in the main manuscript. I recommend merging to abbreviate the data, or send some as supporting data. For example, Figure 1 is not a new compound, so there is no need to put structural formulas here. And Figures 4 and 5 can be merged etc. Maximum 8~9 Figures are enough.
  2. Please add standard deviation with statistics in Figure 11
  3. In Figure 4 and 5, It would be helpful for readers to understand if the Legend's colors were unified. For example, D201-red, MIL-53 blue, MIL-53/D201-black
  4. Authors should include some recent articles about Metal organic frameworks for various applications in their Introduction part. For example, Lee and coworkers previously developed a series of robust MOFs with 3D frameworks and high surface area-to-volume ratios that exhibited superior antibacterial activity. The biomedical applicability of MOF has been demonstrated. [ACS Appl. Mater. Interfaces 12 (2020) 20234–20242. Nanomaterials 11 (2021) 719.]. This is highly relevant to the current work.

Reviewer 2 Report

Efficient removal of azlocillin sodium from water by polysty- 2 rene anion exchange resin supported MIL-53

  • In this article, the authors have declared the results are of adsorption capacity of the composite is 122.3 mg/g when the dosage of the composite is 1.0g/L,
  • Compared with pure MIL-53 material, the composite material exhibits more stable and efficient adsorption performance for target pollutants at different PH values. The adsorption process accords with the quasi-second order kinetic adsorption model and Langmuir adsorption isothermal model. After five times of adsorption and desorption, the removal rate of MIL-53/D201 to azlocillin sodium was still above 87%.
  • It an excellent result in the environmental chemistry to remove other impurities along with the Azlocillin sodium., I suggest authors remove other organic impurities using the same MIL-53/D201.

My Queries:

  1. The authors should explain why the XRD peaks have not shown at 2q of 27.32, 29.8, 30.28, and 36.18 for MIL-53/D201? Any special reason?
  2. When I compared the FT-IR data, some other important peaks have not been assigned, Why?
  1. The FE-SEM images are comparatively good, however, Figure 7 is not clear, authors should provide better elemental information for readers to best understand? Please assign the 2 KeV and 3 KeV for which metals they represent?

 

  1. Authors have not cited this paper in the literature, Appl. Sci. 2021, 11, 9856?
  2. There are several grammar errors and typos such as Azlocillin sometimes capital sometimes small? Which one is correct? plz update them.

Decision: If the above amendments are made, I hope it can be accepted with minor revision.
