Abstract
The procedure for obtaining integrable open spin chain Hamiltonians via reflection matrices is explicitly carried out for some three-state vertex models. We have considered the 19-vertex models of Zamolodchikov-Fateev and Izergin-Korepin, and the -graded 19-vertex models with and invariances. In each case the eigenspectrum is determined by application of the coordinate Bethe Ansatz.
