By analyzing 482 pb-1 of e+e- collision data collected at the center-of-mass energy √s = 4.009 GeV with the BESIII detector, we measure the branching fractions for the semi-leptonic decays , , and to be B( ) = (2.26 ±0.45 ±0.09)%, B( Φμ+νμ) = (1.94 ±0.53 ± 0.09)%, B( Φμ+ ημ+νμ) = (2.42 ± 0.46 ± 0.11)% and B( Φμ+ η'μ+νμ) = (1.06 ± 0.54 ± 0.07)%, where the first and second uncertainties are statistical and systematic, respectively. The branching fractions for the three semi-muonic decays Φμ+ Φμ+νμ, ημ+νμ and η'μ+νμ are determined for the first time and that of Φμ+ Φe+νe is consistent with the world average value within uncertainties.
