Abstract
Integrable Kondo impurities in two cases of one-dimensional q-deformed t-J models are studied by means of the boundary Z(2)-graded quantum inverse sca ttering method. The boundary K matrices depending on the local magnetic mom ents of the impurities are presented as nontrivial realizations of the refl ection equation algebras in an impurity Hilbert space. Furthermore, these m odels are solved by using the algebraic Bethe ansatz method and the Bethe a nsatz equations are obtained.
