Controlled Release of Urea Through Mesoporous Methylcellulose Films Derived From N, N Dimethyl Formamide
TLDR
In this article, the controlled release of urea through mesoporous methylcellulose (MPMC) films with varying concentration of Urea (10, 20, 40, and 50 ) was studied.Abstract:
The controlled release of urea through mesoporous methylcellulose (MPMC) films with varying concentration of urea (10, 20, 40, and 50 wt%) was studied. It was found that the release of urea from methyl cellulose (MC) films take place through pores as well as through bulk of the MC matrix. The release of urea through MPMC film is independent of the initial concentration of urea. The mass of diffused urea is well fitted to the transport equations. The transport of urea is pseudo-Fickian. The optical study exhibits the compactness of the MC film at the high percentage of urea.read more
