A system of nonlinear differential equations, namely, the Belousov-Zhabotinskii reaction model has been investigated for nonlinear self-adjointness using the recent work of Professor N.H.Ibragimov. It is shown that the model is not nonlinearly self-adjoint. The symmetries of the system and nonlinear conservation laws are calculated. The modified system, which is nonlinearly self-adjoint, is also analysed. Its symmetries and conservation laws are presented.
