Reviewer 2 Report

This manuscript (molecules-1174011) reported the preparation of limestone-chitosan-alginate nanocomposites for the removal of brilliant green and Congo red dyes in aqueous solutions. The effect of contact time, temperature, concentration, and pH on the adsorption performance of nanocomposites were investigated in detail. The preparation of limestone-chitosan-alginate nanocomposites with interconnected pores are novel, and this materials shows high adsorption capacity for brilliant green and Congo red. However, there are still some issues to be addressed. Therefore, a major revision is suggested before its acceptance.

  1. Macropore size distributions, nitrogen adsorption/desorption isotherms,BJH mesopore size distribution and BET specific surface area of limestone-chitosan-alginate nanocomposites should be added to characterize the pore structure of the nanocomposites.
  2. The persuasive explanation of adsorption mechanism for dyes should be added.
  3. “2.1.1 SEM stud”should be corrected into “2.1.2 SEM study”.
  4. The English (grammar and syntax) should be improved carefully.
