  Because the properties of the QCD phase transition and the chiral magnetic
effect (CME) depend on the number of quark flavors ($N_{f}$) and quark mass,
relativistic heavy-ion collisions provide a natural environment to investigate
the flavor features if quark deconfinement occurs. We introduce an initial
two-flavor or three-flavor dipole charge separation into a multiphase transport
(AMPT) model to investigate the flavor dependence of the CME. By taking
advantage of the recent ALICE data of charge azimuthal correlations with
identified hadrons, we attempt to disentangle two-flavor and three-flavor CME
scenarios in Pb+Pb collisions at 2.76 TeV. We find that the experimental data
show a certain potential to distinguish the two scenarios, therefore we further
suggest to collect more data to clarify the possible flavor dependence in
future experiments.
