Abstract

Urea release from a scoop of coated beads in a given volume of a well stirred liquid has been investigated analytically and experimentally. A method for determining the fractional cumulative release and fractional release rate curves for the scoop without knowing particle number and radii is presented. The representative D/K_b for a scoop of urea beads spray coated with ethyl cellulose is near 3.5 × 10^-8 cm²/s, and that with cellulose acetate phthalate is near 7 × 10^-8 cm²/s. © 2007 Taiwan Institute of Chemical Engineers.
