Abstract

The objective of this study was to measure the release of biologically available ions from microcapsules with ion permeable membranes as a function of counterion, concentration and temperature. A heterogeneous polymerization technique was utilized to prepare a series of microcapsules using an ethylene glycol based polyurethane containing different aqueous solutions of potassium phosphate dibasic, sodium phosphate dibasic, potassium phosphate monobasic, calcium nitrate, calcium chloride and calcium acetate. Ion release profiles were studied as a function of initial ion concentration within the microcapsule, ion type and counterion type, and temperature. The preparation of microcapsules with controlled release profiles appears promising based on counterion selection and concentration.
