The modified Kordeweg-de Vries (mKdV) equation is derived in this study for dust acoustic (DA) solitary waves in an unmagnetized dusty plasma consisting of q-nonextensive electrons, vortex-like (trapped) distributed ions. The reductive perturbation technique has been employed to derive the modified KdV equation. A non-linear pseudo-potential technique is also used to investigate the arbitrary amplitude DA solitary waves. The numerical results show the variation of amplitude, phase velocity and width of the nonlinear waves for different parameters.
