Abstract
The release of urea from a coated urea bead in water and in aqueous gl ycerol solutions is investigated experimentally. Experimental data of 19 release systems are analyzed and correlated using the dimensionless equations that have been discussed in part 1 of this work. The ratio of partition constants and the ratio of diffusivity to partition const ant are determined.
