Biodegradation of chitosan
WebThe biodegradation test was left on for ten (10) weeks. Changes in mass, which is considered as the progress of biodegradation (Azevedo et al., 2004), were measured after the first four (4) weeks and at the end of the tenth week. The percentage change in mass after weeks of immersion, M Δ, was calculated for every sample using Equation (1).
