Descrizione:
In this study, chitosans was deacetylated with 45% sodium hydroxide under air atmosphere at 80 C for up to 3 hour, to obtain deacetylated chitosan DDA measure by potentiometer titration method. Deacylated chitosan polymerizing methacrylic acid (DDCSPMAA) nanoparticle is an interesting material for use in controlled release for K fertilizers. In this work chitosan nanoparticles were obtained by polymerizing methacrylic acid for the incorporation of potassium chloride for potassium(K) fertilizers. The interaction and stability of chitosan nanoparticle suspensions containing K was evaluated by SEM. The SEM results indicated the existence of electrostatic interactions between chitosan nanoparticles and the elements K. The stability of the DDCSPMAA colloidal suspension was higher with the addition of potassium due to the higher anion charge of potassium chloride. The use of slow release fertilizer has become a new trend to save fertilizer consumption and to minimize environmental pollution. Due to its polymeric cationic, biodegradable, bioabsorbable, and bactericidal characteristics.
