The procedure for obtaining integrable open spin chain Hamiltonians via reflection matrices explicitly carried out for some three-state vertex models. We have considered the 19-vertex models of Zamolodchikov-Fateev and Izergin-Korepin and the Z2 graded 19-vertex models with sl(2/1) and osp(1/2) invariances. In each case the eigenspectrum is determined by application of the coordinate Bethe ansatz.Financiadora de Estudos e ProjetosO procedimento para resolução de cadeias quânticas integráveis de spin 1 com termos de superfícies diagonais para os modelos de vértices de três estados é apresentado.
