Polycyclic aromatic hydrocarbons (PAH) are a type of molecule created during incomplete combustion of coal, tar, gas, and other similar material. These molecules are very stable which makes them persistent in the environment. As time goes on, PAHs also become increasingly more difficult to remove. Using ultrasound, we aim to activate persulfate to try and oxidize the PAHs to make them easier to remove from sediment.
