Plasmas Damping solitary wave in dusty plasma is studied by considering the collision effect between dust grains and ions. It can be described by a KdV type equation in which a damping term of u 2 exist. It is found that both the amplitude and propagation velocity of the solitary wave decrease with time exponentially. Our results are compared with another KdV type equation with the damping term of u. It is noted that the damping rate of the KdV type equation with the damping term of u 2 is larger than that with the term of u. It is found that the damping rate is proportional to the collision frequency between dust grains and ions. V C 2012 American Institute of Physics.
