In this paper, the Gauss-Seidel and successive over-relaxation iteration methods for quaternion linear systems Ax = b are studied and the structure-preserving algorithms of these methods are obtained. The convergence and computational cost of these iteration methods are discussed and numerical examples are given to demonstrate their efficiency. As an application, two kinds of structure-preserving iterative algorithms are applied to solve elliptic biquaternion linear systems Ax = b.
