Reviewer 2 Report
1. Figure 4 – The FTIR analysis should be merged into 1 diagram.
2. Figure 5 is divided into 3 different figures – why? the differences between peak shifts can be shown in one figure. Additionally, numbers on figures 1, 2, 3 are not mentioned in the caption.
3. Authors should add the SEM-EDS microphotographs for better imaging of the adsorption process.
4. Please cite the article below as it contains many information concerning the adsorption process: DOI: 10.1007/s13762-019-02446-9
5. Authors could add a figure in the supplement showing the influence of the adsorbent dosage on the adsorption process.

Comments to the Author
Title: Effect of oxycations in clay mineral on adsorption – vanadyl exchange bentonites and their ability for amiloride removal.
The authors should apply the following comments. So, the manuscript can be accepted after major revision.
- Introduction
Application of vanadium ion containing bentonite for the adsorption process is not sufficiently substantiated. All references cited relate to the use of vanidium oxide. So this part should be rewritten (page 2-3, line 81-86).
- In subsection 2.1.2.
The structure of the bentonite after modification will be changed such parameters, as the interlayer distances (can be calculated using Bragg’s law), the thickness of the bentonite (can be calculated through Debye-Scherer equation) and the number of layers of the bentonite. And these change play important role during the adsorption prosesses. So, mentioned parameters must be calculated acoording XRD results (page 3-4, line 115-136).
- In subsection 2.3.2.
Page 7, line 222. Should be Table 2.

Comment 1: Application of vanadium ion containing bentonite for the adsorption process is not sufficiently substantiated. All references cited relate to the use of vanidium oxide. So this part should be rewritten (page 2-3, line 81-86).
Response: In fact, we observed two studies in the literature and they are included in the revised version of the manuscript. Please, see Introduction lines 103-109
Comment 2: In subsection 2.1.2. The structure of the bentonite after modification will be changed such parameters, as the interlayer distances (can be calculated using Bragg’s law), the thickness of the bentonite (can be calculated through Debye-Scherer equation) and the number of layers of the bentonite. And these change play important role during the adsorption prosesses. So, mentioned parameters must be calculated acoording XRD results (page 3-4, line 115-136).
Response: We modified text as suggested. We consider that the information improved text. Experimental please see lines 169-176. In results and discussion, we included a new Table with 2teta values, d001, thickness of the bentonite and interlayer distance. Please new Table 2 and new comments in Lines 263-267
Comment 3: In subsection 2.3.2. Page 7, line 222. Should be Table 2.
Response: It was a mistake. Text was modified please see line 393. Table 3.
