A "soil absorption coefficient" study is to predict the mobility of a pesticide in the environment. If carried out over a range of pesticide concentrations the result can be fitted to an equation called the "Freundlich isotherm" that is used to describing adsorption. This equation is Q=k C 1/n, where Q is the amount of the sorbed pesticide in equilibrium, C is the concentration of the pesticide in solution, K and n are empirical constants, Kf is called the sorption coefficient. An n value of 1 denotes a linear sorption process.
