The influence of thermal diffusion (Soret term) on heat and mass transfer flow over a vertical channel with magnetic field intensity was studied. The non-linear partial differential equations governing the flow are non-dimensionalised, transformed to a steady state and solved semi-analytically using perturbation method. Graphical results for velocity, temperature, concentration, skin friction, Nusselt number and Sherwood number have been obtained, to show the effects of different parameters entering into the problem. Results from these study shows that velocity and concentration increase with the increase in the thermal diffusion (Soret term). It is fascinating to note thatthe solution of the present work aligns with that of the anchor paper by silencing the thermal diffusion (Soret term) in the present work.
