Problem 1. Diffusion of 2,4,6-Trichlorophenol (TCP) Through a Capping Sediment Layer (50 pts) Begin this problem by calculating the steady-state flux (mg TCP / (m2 day)) for De = 2.5x10-6 cm2/s, Rf =100, a = 35 cm, and A* = 800 mg TCP/L. Then, use equation (11) from the Thoma et al. article to calculate the flux of TCP from the capping sediment to the overlying water (mg TCP / (m2 day)) as a function of time. Use only as many values of n in your series solution as needed for accuracy. Hand in a plot of this result and identify the time required for the flux of TCP to achieve 1% of its steady-state maximum value. This time represents the TCP flux delay time caused by the clean capping sediment. Now, double Rf and repeat the calculations, starting with the steady-state flux. What effect does Rf have on the steady-state TCP flux and the delay time? Repeat this calculation using the original Rf (100) and double the value of a. What effect does a have on the steady-state TCP flux and the delay time? Hand in the steady-state fluxes and the plots and explain in a few sentences your key results.
