In this work, utilizing perturbation theory we theoretically calculate the magneto-optical absorption coefficient in monolayer graphene, subjected to a perpendicular magnetic field and an intense electromagnetic wave. The electron-impurity interaction is taken into account at low temperatures. We found the cyclotron-impurity resonant effect in the absorption spectra. The half width at half maximum (HWHM) of cyclotron resonant peaks is obtained by computational method and shown as functions of the magnetic field and temperature. Our results are in good agreement with available experiments for specific parameters of the material.
