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”
24 &
65 The citation must be put before point such as “[1].” Instead of “ .[1]”
52 The citation jumped from [2] to [11] and the contain of reference no [11] is not maching with the statement. Please rearrange and refer them correctly.
53-55 There are no reference no 33-41. The total references are only 27.
58 There is no scheme 2. Please add it 65 There is no reference no 42.
66-72, 182,
429
The sentences are ambiguous.
79-80 The reference (No [4]) is no maching (wrong).
104 The reference (No [4]) is no maching (wrong). It does not deal with rice straw 104
The insulation of cellulose must state clearly especially how to remove lignin as well as hemicelluloce from the rice straw. Otherwise, the lignin will still be in the sample and many functional groups will be observed from FTIR.
109, 119, and so
on
Experimental method must be discribed using past tense.
117 An effort has been done to remove residual monomers by washing with distilled water, but no effort has been taken to remove the homopolymer may be produced. How did the author
consider the homopolymer from MBA or AA?
125 &
152 Please add the equation number.
191 There is no legend for copolymer B in Figure 1.
197 Which one is righ, with increasing the radiation doses, the grafting of copolymer A dan B increased linearly or 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.”
246 Give deferent mark/color in the figure 2 for cellulose and coplymer B.
266 It the peak at 550˚C for copolymer A endothermic? It is contradiciton with the figure and previous explanation.
270 It must be thermal properties instead of properties thermal.
299-
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.
422 Fig 6. The Y axis was double value???
478
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.
483 Where does the sulfur atom come from?
629 What is the “unsur” in Table 2?
666 -
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!!!
Use only the recent (up to date) references.
Final comments and recommendations:
Since rice straw is a lignocellulose, the author must clearly explane the purification and the purity of cellulose, otherwise, the role of lignin and hemicellulose sholud be explaned.
The author must also consider the existance of poly(acrilic acid) homopolymer which may not grafted in the cellulose but take a role in the Pb absorption.
The Author must rechek the references, since there are fatal errors in citation and listing.
Please consider to revise the highlighet part in the text.
