In this work, authors performed an extensive analysis of the effect of preparation conditions on the adsorption characteristics of activated carbon obtained from two types of organic wastes. The methodology, experimental results and interpretation look convincing, and the paper can be recommended for publication after minor corrections.

Minor corrections

line 608 check the units

line 669 instead of adsorption capacity, adsorbed amount can be used.

line 669 it is not very clear, what is the meaning of the threshold.

line 681-683 this is a natural phenomenon, related to the definition and calculation of the adsorption capacity.
