The rate of droplet settling and mass transfer are known to be quite sensitive to small quantities of surface active impurity present in the interface. The purpose of this paper is to examine critically several of the models used for predicting the rate of inhibited Stokesian settling and to compute the rate of mass transfer from the surface of a slowly settling droplet in the presence of surface active impurities which are distributed over the surface.
