In this paper a method of direct derivation for the universal R matrix of quantum group Uq(SU(11)) is given. It is simple and efficient for quantum groups of low rank at least. By the application of the R matrix obtained, the explicit expression for Casimir invariant of the above guantum group is given. As an application, the second order Casimir operator is rederived as well.
