  We propose a unified description of transport in graphene with adsorbates
that fully takes into account localization effects and loss of electronic
coherence due to inelastic processes. We focus in particular on the role of the
scattering properties of the adsorbates and analyze in detail cases with
resonant or non resonant scattering. For both models we identify several
regimes of conduction depending on the value of the Fermi energy. Sufficiently
far from the Dirac energy and at sufficiently small concentrations the
semi-classical theory can be a good approximation. Near the Dirac energy we
identify different quantum regimes, where the conductivity presents universal
behaviors.
