Abstract
A t - J model for correlated electrons with impurities is proposed. The imp urities are introduced in such a way that integrability of the model in one dimension is not violated. The algebraic Bethe ansatz solution of the mode l is also given and it is shown that the Bethe states are highest weight st ates with respect to the supersymmetry algebra gl(2/1).
