Unformatted text preview: 1. Calculate C sat a and K H (Henrys constant) in dimensionless form. 2. Since you know the actual concentration in the water, calculate the actual concentration in the air using K H . 3. Using Karickhoffs formula, calculate K d (the water-solids partitioning coefficient) and then use it to calculate the actual concentration in the sediments. 4. You now know the concentration in all 3 phases. Use the mass balance to calculate the total mass of PCP in the sample. 5. Calculate the fraction of the mass that is in each phase (air, water, sediments). 6. If these sediments are representative of a contaminated zone containing 10 metric tons (10,000 kg) of sediments, how much PCP is present in the sediments? 2) Mass balance problem 4.5 in Watts (20 points) 3) Sorption problem 5.23 in Watts (10 points)...
