We present Suzaku observations of three iron low-ionization broad absorption line quasars (FeLoBALs). We detect J1723+5553 (3σ) in the observed 2-10 keV band, and constrain its intrinsic N H column density to N H > 6 × 1023 cm–2 by modeling its X-ray hardness ratio. We study the broadband spectral index, αox, between the X-ray and UV bands by combining the X-ray measurements and the UV flux extrapolated from Two Micron All Sky Survey magnitudes, assuming a range of intrinsic column densities, and then comparing the αox values for the three FeLoBALs with those from a large sample of normal quasars. We find that the FeLoBALs are consistent with the spectral energy distribution of normal quasars if the intrinsic N H column densities are N H > 7 × 1023 cm–2 for J0943+5417, N H>2 × 1024 cm–2 for J1352+4293, and 6 × 1023 cm–2 < N H < 3 × 1024 cm–2 for J1723+5553. At these large intrinsic column densities, the optical depth from Thomson scattering can reach ~6, which will significantly modulate the UV flux. Our results suggest that the X-ray absorbing material could be located at a different place from the UV absorbing wind, likely between the X-ray and UV emitting regions. We find a significant kinetic feedback efficiency for FeLoBALs, indicating that the outflows are an important feedback mechanism in quasars.
