N2 - A simple and precise method for batch sorption with soot was developed. This method was applied to determine of full-range isotherms with selected hydrophobic organic chemical and reference diesel soot material (SRM 2975). The equilibration time with solute was 3, 7, 13, 19, 32, 59, and 88 days. Kd values were observed to increase over the course of equilibration time between 3 and 13 days, but decreased as equilibration time approach 59 days. The Kd values appeared to stabilized after 59 days with statistical student t-tests showing that Kd values for the 59 and 88 day samples were from two populations with the same mean. Sixty day equilibration was required for soot particles to become the equilibration with solute and water molecules.
