Round 1

Reviewer 1 Report

The authors have described a very important study on removing boron from geothermal sources and this is indeed a topic of significant interest.  The use of a liquid membrane system, specifically a polymer inclusion membrane is also interesting. 

1.The data are presented clearly but no possible explanations or mechanisms have been provided. Without these, the paper only boils down to a "trial-and-error" study without any major scientific insight. In my view, this is the biggest flaw of this paper. 

For example, the authors have identified some optimum conditions for the donor phase and acceptor phase without ever trying to analyze why such conditions work well. Moreover, the results from an actual geothermal water are very important and it is interesting to note that competitive adsorption did not affect the boron uptake significantly. But once again, the authors did not provide any explanation or mechanistic insight into this. 

2.Lastly, the authors should provide the relevant references to support some of their statements - please see the attached pdf.
