The oxidation of cellulose to dialdehyde (DAC) is a process that has received increased interest during recent years. Herein, kinetic modeling the reaction with sodium periodate as an oxidizing agent was performed quantify rate-limiting steps and overall kinetics reaction. Considering pseudo-first-order reaction, general rate expression derived elucidate impact pH, concentration, temperature on concurrent formation degradation products. Experimental concentration profiles were utilized determine constants for DAC (k1), constant (k2), (k3), confirming follows Notably, increase in more pronounced effect k1 compared influence IO4− concentration. In contrast, k2 k3 display minimal changes response but significantly increasing temperature. model developed may help understanding providing valuable information optimizing toward faster higher yield target product.

Abstract Heavy metals have attracted considerable attention lately because of their widespread occurrence in aquatic environments and potential biological toxicity to animals human. The current investigation focused on synthesizing the DAC@TCH nanobiosorbent by coupling dialdehyde cellulose with thiocarbohydrazide ligand. Subsequent characterization was carried out utilizing various analytical methods such as elemental analysis, scanning electron microscopy (SEM), transmission (TEM), Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA DTA). DFT calculations were utilized verify molecular structure, frontier orbitals (FMOs), electrostatic (MEP) reactivity descriptor for all phases. In vitro experiments conducted evaluate properties nanobiosorbent. These findings revealed that synthesized has been observed show effective antibacterial IZD value against E. Coli (28 mm) which is superior efficacy standard drug amoxicillin used (5 mm). Furthermore, silico activities (molecular docking) indicated this exhibit excellent docking score ( − 7.4237 kcal/mol) (−7.1325 S. aureus and, coli, respectively. Meanwhile binding energies (best scores) kcal/mol Amoxicillin are (−5.8090) (−6.7442) Drug-likeness rules like Lipinski’s, Veber’s Egan’s considered a more comprehensive evaluation. prepared investigated its adsorb metal ions (Ag + , Hg 2+ Cu ) from diverse water samples.
