The Freundlich equation, X/m = K CeN, is frequently used to express the partitioning of pesticides between solid (soil, sediment) and aqueous phases. When designing adsorption-desorption experiments, it would be useful to be able to estimate the equilibrium concentration, Ce, in terms of the initial concentration, Co, if reasonable estimates of K and N can be made. Because of the usual non-integer nature of N, only a numerical solution of the Freundlich equation is possible for Ce in terms of Co. A simple computer program is presented which produces almost an exact solution for the value of Ce.
