However, most nitrogen fertilizers are substances with high solubility of ions and are very susceptible to leaching and volatilization. To minimize these losses, an alternative is the creation of a physical barrier around granules. One way is to coat granules with polymers. In the present work urea granules were coated with polyhydroxybutyrate and ethyl cellulose in various conditions in the presence of emulsifiers. The original granules and the final products were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and thermogravimetry, to evaluate the surface morphology, the interaction between the granules and the coating, and the rates of mass change. The rates of urea release in distilled water were measured with a commercial enzyme kit. It is shown that those polymers are effective for coating of granules, leading to reduction of rates of urea dissolution in water.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-04-15T14:12:42Z No. of bitstreams: 1 jf401185y.pdf: 1278639 bytes, checksum: 177484a8161527544db4eecf3a06c912 (MD5)Approved for entry into archive by LIVIA FREITAS (livia.freitas@ufba.br) on 2014-07-09T13:59:13Z (GMT) No. of bitstreams: 1 jf401185y.pdf: 1278639 bytes, checksum: 177484a8161527544db4eecf3a06c912 (MD5)Made available in DSpace on 2014-07-09T13:59:13Z (GMT).
