The word of “Simultaneous method”in the title, seems has no meaning either in the introduction or in the discussion, and considering the journal scope it is better to be changed such as “using gamma irradiation method”

Please add the equation number. Revised 191 There is no legend for copolymer B in Figure 1. Revised

Which one is righ, with increasing the radiation doses, the grafting of copolymer A dan B
increased linearly or logarithmic? increased logarithmic
211- 214
What the evident (data or references) for the statement of:
“Increased percentage of grafting copolymer A and B obtained is different because amount of radicals formed, radical position, availability and diffusion of monomer and gel formation.”

cellulose and coplymer B. Original data from DSC cannot be changed

It the peak at 550˚C for copolymer A
endothermic? It is contradiciton with the figure
and previous explanation. revised
270 It must be thermal properties instead of properties
thermal. Thermal stability

It is said that “FTIR spectra cellulose-MBA-AA indicates the occurrence of crosslinking
N,N'-methylenebisacrylamide (MBA) and grafting from acrylic acid because it appears that there are no peaks in the FTIR spectra pure cellulose.”
How did the crosslinking and grafting reactions happen? As consequnecy of the reaction, some functional groups may disappear and make a new chemical bond (new functional
group).
How about the existance of polyacrilic acid homopolymer which have not been removed.
polyacrilic acid homopolymer completely removed

It is said that “The fig.8 indicates that the optimum adsorption of Pb is 90.28% at neutral (pH ± 7). ..”
However, tt is contradiction with Fig. 6 where the adsorption of Pb could reach more than
98%. How it can be explaned.
90, 28% on 3 ppm 99,87% on 10 ppm Miss explanation

Please recheck all references. Some references were not used, some others were not listed and some others also were cited incorrectly. It is fatal error!!!
