We investigate the Ds+ → K+ K- π+ decay theoretically with the final state interactions, which is based on the chiral unitary approach and takes into account the external and internal W-emission mechanisms at the quark level. Only considering three resonances contributions, the f0(980) in S-wave, the K*(892)0 and ϕ(1020) in P-wave, one can make a good description of the recent experimental data from BESIII Collaboration, where the contribution from S-wave is found to be small. Besides, we also make a calculation of the corresponding branching fractions, which are consistent with the results of BESIII Collaboration and Particle Data Group.
