A cellulose-based hydrogel was synthesized using a physical method from sodium salt of carboxymethyl cellulose (Na-CMC) and tannic acid (TA). The structure, morphology, swelling studies, biodegradability and antibacterial activity of hydrogel were deduced. The hydrogel characteristics revealed an amorphous nature with a pore size of 4.7 µm. The results showed that the hydrogel had a high swelling capacity at different pH solutions, and the maximum swelling percentage was 200% at pH 10. The kinetic studies showed that its adsorption property was non-Fickian. The antibacterial activity against four pathogens was analyzed, and inhibition zones were observed against all the pathogens. The degradation studies of the hydrogel in water and soil were obtained after nine weeks as 89.20 ± 1.15% and 81.49 ± 0.23%, respectively. The fungus generated during the degradation was Aspergillus species. Thus this study provided a feasible strategy that the hydrogel shows the application in the field of wastewater treatment, medical, agriculture etc. |
