Abstract:	We derive and classify all solutions of the boundary Yang-Baxter equation (or the reflection equation) for the 19-vertex model associated with . An integrable XXZ spin-1 chain Hamiltonian with general boundary interactions is also obtained.

Keywords:	Reflection K-matrix Boundary Spin chain Yang-Baxter equation
