[en] Physical processes in near-wall plasma of a tokamak with poloidal magnetic divertor is investigated. In the frames of one-dimensional hydrodynamic equations of longitudinal energy and particle transfer are stationary distributions of plasma parameters in a divertor layer and in divertor volume with the presence of impurity atoms flux from divertor plate surfaces due to ion sputtering. Self-matched plasma and impurity model consideration permits to determine impurity real level in considered divertor regimes, to investigate their spatial effect on the value of plasma parameters in divertor. Numerical calculations are compared with the data obtained at ASDEX device
