Reviewer 2 Report

This work experimentally investigates the new method that motivating the flow within the concentration boundary layer. An elaborate design has been demonstrated in the present work. The experimental results could help readers to understand the flow pattern under the effect of the applied current and magnetic field. It is to recommend introducing the velocity measurement approach in the manuscript rather than cite your previous work, since it is important to your experiment.

1. This work experimentally investigates the new method that motivating the flow within the concentration boundary layer. An elaborate design has been demonstrated in the present work.

It is to recommend introducing the velocity measurement approach in the manuscript rather than cite your previous work, since it is important to your experiment.

Response: Thank you very much for your useful suggestion. We revised the manuscript under your suggestion on page 4 from line 151 to line 153 as follows:

The liquid velocity was measured by using polystyrene particles with a diameter of 80 μm and the video recorder. The velocity measuring range was from -4 mm to 4 mm in the x-direction and 120 μm to 280 μm in the y-direction.

Reviewer 3 Report

 

Generally work is write well done and results are very interesting. The mass transfer between solids and liquids are important especially in the micro-scale. Because micro-scale mechanism of mass transport determine process in the macro-scale. Stimulating a boundary layer by convection is fundamental and of course effective local stirring successfully improve yield of process. Before work acceptance Authors should add some additional explanations.

1. Authors should add to view of experimental apparatus thickness of the cathode, anode and insulator (dimension in the y-direction).

2. Position of magnetic stirrer with respect to vessel is essential for readers.

3. Table 1, last column, should be write cathode.

4. Please explain in the paper where was zone of determine velocity under DC+MF condition (figure 3).

5. Why experiments was conducted only by 20 seconds or why Authors presented results only to 20 seconds. Please explain in the section 2.
