The study looked at how phosphorus sticks to sediment in Dishui Lake. They found that most phosphorus stuck to the sediment within 24 hours. The amount of phosphorus sticking depended on how much was in the water to start with. The sediment near South Isle could hold the most phosphorus, acting like a sponge to soak it up. This could help keep the water clean by storing excess phosphorus. The researchers used different equations to describe how phosphorus sticks to the sediment, and found that one called the Langmuir equation worked best.
