Reply to the 'Comment on "Unravelling the kinetics, isotherms, thermodynamics, and mass transfer behaviours of Zeolite Socony Mobil - 5 in removing hydrogen sulphide resulting from a dark fermentative biohydrogen production process"' by K. H. Chu, M. A. Hashim and M. Hafiz Zawawi, , 2025, , DOI: 10.1039/D4CP04682J.

In this reply, we address the concerns raised regarding the theoretical consistency of the modeling approaches used in our original study on hydrogen sulfide adsorption onto ZSM-5. Specifically, the issues relate to the application of the Temkin isotherm, the Weber-Morris intraparticle diffusion model, and the use of a dimensional distribution coefficient in the thermodynamic analysis. We acknowledge that the simplified Temkin model was misapplied and does not strictly conform to theoretical requirements; however, it was used to represent mid-range adsorption behavior consistent with our experimental conditions.

Adsorptive Elimination of Heavy Metals from Aqueous Solution Using Magnetic Chitosan/Cellulose-Fe(III) Composite as a Bio-Sorbent.

Magnetic chitosan/cellulose nanofiber-Fe(III) [M-Ch/CNF-Fe(III)] composites were isolated for the elimination of Cr(VI), Cu(II), and Pb(II) from aqueous solution. Various analytical methods, such as field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction analysis (XRD), and thermogravimetric analysis (TGA) were employed to determine the morphological, physicochemical, and thermal properties of the isolated M-Ch/CNF-Fe(III) composites. It was found that the M-Ch/CNF-Fe(III) composites were porous materials, and they have the potential to be implemented as an adsorbent for heavy metals removal.
